DES NAMIDDAGS TE DRIE UUR

Aan het einde van mijn academische studie gekomen, wil ik
op deze plaats mijn grooten dank betuigen aan allen, die aan
mijn wetenschappelijke opleiding hebben medegewerkt en wel in
het bijzonder aan mijn prpmotor. Prof. Dr. A. Pulle, bij wien ik
het voorrecht heb zoo vele jaren reeds assistent te zijn, en onder
wiens leiding dit werk tot stand is gekomen. Voorts breng ik
mijn dank aan het bestuur van het Miquel-fonds, dat mij in staat
stelde eenige weken te werken in de herbaria te Kew, Londen
en Parijs, en ten slotte aan allen, die mij op eenigerlei wijze
behulpzaam zijn geweest bij het gereedmaken van dit proefschrift.

The great difficulties arising in the identification of a number
of plants belonging to the genus Evolvulus, which plants were
found in several recent collections of Convolvulaceae and were
kindly entrusted to me for study, induced me to submit this
genus to a further examination. It soon proved how great the
prevailing confusion was, both in literature and in the herbaria.
Various species were again and again wrongly interpreted and
this especially concerns those which had been described by the
older authors. Thanks to the invaluable help of a great number
of herbaria I was in a position to bring about some order in the
genus. Still numerous questions remain unsolved. A close study
of living material, preferably on the habitat itself, will often be
of great value here. I had a great quantity of material at my
disposal, kindly lent me by the following herbaria. (These her-
baria are indicated in the taxonomical part by the abbreviations
in parentheses.)

universiteit, Utrecht.nbsp;(U)

Here I wish to express my best thanks to the directors of these
herbaria for their great assistance and especially to the directors
and staff of the herbaria and libraries I have personally visited,
viz. the quot;Jardin Botanique de I'Etatquot;, Brussels, the Royal Bo-
tanic Gardens, Kew, the Linnean Society of London, the British
Museum of Natural History, London, the quot;Muséum national
d'Histoire naturelle quot;, Paris and the quot;Musée du Congo Beigequot;,
Tervueren. Further my gratitude to the director and staff of the

quot;Rijks Herbariumquot; at Leyden, the collections and library of which
I have so often consulted, and finally my most sincere thanks
to Professor Dr. A. Pulle, Director of the quot;Botanisch Museum en
Herbarium van de Rijks Universiteitquot; at Utrecht, under whose
direction this work was completed. His great assistance, his
continual interest in the work and his advice in the composition
thereof have been of inestimable value to me.

The genus Evolvulus i ) was first described by Linnaeus
in the second edition of his Species Plantarum. 2) Linnaeus
distinguished 5 species here; three of the five species also occur
in the first edition of the Species Plantarum ( 1753 ), but under the
name of Convolvulus. They are C. nummularius, C. atsinoides
and C. tndentatus.

The description which Linnaeus gave of the genus in
1762 was rather incomplete, and the important characteristic,
that of the two 2-cleft styles, is not mentioned in it. A better
diagnosis follows in the Genera Plantarum, ed. 6 (1764). Here
there is a fairly exact description of the styles: quot;styli 4, capillares,
divergentes, longit. staminum. Stigmata simpliciaquot;.

To the species Linnaeus described from India, B u r m a n s )
added in 1768 two others, neither of which, however, belonged
to the genus. Lamarck's Encyclopédie ^ ) gives a summary
of the species known in 1789, 8 in number, 3 of these, however,
do not belong to the genus. PersoonS) gives 9 species, two
of which were described by Ruiz and P a v o n in their Flora
Peruviana. A general view of the Australian forms was given
by Robert Brown 6) in 1810, of the Asiatic forms by
Roxburgh'^) in 1832. Poiret«) in the Supplement to
Lamarck's Encyclopédie gives a summary of the species known
in 1813. These are indeed all Evolvulus species. After P o i r e t

the number of species described gradually increases. The sum-
mary Choisyi) gave in his Convolvulaceae Rariores followed
by his monograph in De Candolles Prodromus is of great interest
here. C h o i s y mentions 60 species, six of which are but little
known. The most important and extensive work on the genus
is Meissner's2) in the Flora Brasiliensis. Meissner
gives a general view of the Brazilian species, but also adds a
few others, but not Brazilian. The total number he mentions
amounts to 62, several new ones being among them. A number
of new species have still been described after Meissner,
justly or unjustly as new, the greater part from South America,
but also from Mexico and the West Indian Islands. However
a general revision of the genus did not see the hght after
C h o i s y's Monograph.

Roots. Roots annual or mostly perennial, in the former
case thin, vertical with slender lateral branches, in the latter
thin or mostly thicker and then often a perpendicular tap-root,
also oblique or almost horizontal. Towards the top the root
generally becomes gradually thicker and lignescent and bears
at the crown one or mostly more stems. In E. pusillus Choisy
adventitious roots often occur at the nodes, in E. nummularius L.,
this is usual.

Stems. In the frutescent and suffrutescent species the
stems are mostly erect, are either branched or not, the branches
often erecto-patent; the height is generally but small, the largest
forms attain a height of about 1.20 metre. In the perennial species
the stem or the stems are erect or ascending or also they are
often prostrate, branched in more or less degree, often lignescent
at the base; in the few annual species the stems are mostly
upright; this is often the case in annual specimens of perennial
species, at least, in so far as they are known.

Leaves. The leaves are small to fairly large; very large
leaves do not occur. Species with large leaves are for example
E. cardiophyllus and E. lati[olius; also in E. glaber and E. num-
mularius rather large leaves may occur, when growing in a
fertile habitat. They are very small to almost scale-like in E.
squamosus. The leaves are always alternate, with entire margin,
their form varies from subulate to linear, lanceolate, oblong, ovate
and orbicular with every intermediate transition. They are sess-
ile or short-petiolate; long petioles do not occur. In general the
leaves are membranaceous, in some cases they are somewhat
thicker. The indumentum is very variable; the kind of pubescence
most prevailing consists of appressed, loosely appressed or
spreading to patent villose hairs, often long and mostly soft.
Sericeous hairs also occur very frequently; these are always
strongly appressed, generally more or less shining, straight, all
pointing in the same direction. Now and then a woolly indumen-
tum is found, also a short tomentum, the latter often mixed with
longer hairs. All kinds of transitions appear in the pubescence
and also the density of the hairs is very variable.

The nervation consists of a midrib and one to several pairs
of lateral nerves. Often the nervation becomes indistinct owing
to the dense hairiness. Generally it is most distinctly to be seen
underneath. The lateral nerves arise at different heights in the
leaf or they arise quite near the base. This is especially the
case in leaves with a broad subcordate or cordate leaf-base.
But also it occurs in narrower leaves. Here I refer to E. sericeus
Sw. in which 1 or more pairs of lateral nerves always arise at
the base and are long-ascending.

Inflorescence. The inflorescences are of dichasial
character. This is distinctly expressed in the species with
developed peduncles and with more-flowered inflorescences, the
flowers of which are distinctly pedicellate. At the base of the
pedicel of the terminal flower occur 2 bracteoles, each with a
lateral branch in their axil. In their turn these branches also bear
terminal flowers and bracteoles, with or without developed flow-
ers. The lateral branch or the lateral flower in the axil of

bracteole ß is often more strongly developed than that in the
axil of bracteole a (quot;Förderung aus ßquot;. Eich 1er). If the lateral
branches of the dichasium are not developed, then we get a
peduncle, which is one-flowered. This has given rise to the fact
we sometimes find in descriptions that the pedicel should bear
2 bracteoles in the middle. What is considered here as a pedicel
consists indeed of a peduncle and the pedicel of the terminal
flower as a continuation thereof. Should the peduncle be missing,
then the flowers are situated immediately in the leaf-axils, with
or without pedicels. In the case only one axillary flower develops
the undeveloped lateral axes of the dichasium are to be seen in
the axils of the bracteoles. The species with developed peduncle
generally bear inflorescences along a great part of the stem;
this is also often the case in a great part of the species lacking
peduncles (Alsinoidei—Epedunculati, Passerinoidei). In the
Phyllostachyi, Involucrati and Lagopodini the flowers are aggre-
gate in spike-like inflorescences at the end of stem and branches.
Then they are situated either in the axils of normal leaves or
in the axils of narrower bracts.

Calyx. The calyx consists of 5 equal or slightly unequal
sepals, with quincuncial aestivation. In the majority of the species
they are lanceolate or narrow-lanceolate, sometimes, however,
they are broader, then the inner ones often have a scarious
margin. In general the hairiness corresponds approximately with
that of the stems and leaves, but is often somewhat more spread-
ing. The calyx is generally persistent in fruit and not or very
slightly enlarging.

Corolla. The 5-merous corolla is rotate, funnel-shaped or
salver-shaped; the hmb i ) is subentire, superficially lobed or
deeply lobed; on the outside 5 distinct, hairy, midpetaline areas
are always to be perceived, on the inside the corolla remains
glabrous. The corolla is generally small, in most cases longer than
the calyx, sometimes as long or somewhat shorter (E. simplex.

It is quite possible, that the margin of the corolla might be of importance
with living material in distinguishing the species; the delicacy of the corolla
in dried material frequently admits of no close examination.

E. ovatus); the greatest occurs in E. speciosus, where the dia-
meter amounts to 30 mm. The colour of the corolla is as a rule
pale- or dark-blue or pale-violet or white, according to the col-
lectors the colour is yellow in E. paniculatus. In E. sericeus fading
sometimes takes place in drying, the corolla then becomes bright
yellow.

Stamens. There are 5 stamens and they are alternate
with the corolla-lobes; the filaments are developed, they are
situated at the mouth of the generally very short, sometimes
longer corolla-tube, they are glabrous, filiform and not enlarged
at the base or very little so. In some species a small tooth occurs
on each side of their bases. The anthers are ovate to oblong or
linear, 2-celled, introrse, each cell dehiscing by a longitudinal
slit. Pollen globular, dodecaedrical (according to H a Hi er).

Pistil. The ovary is globular, ovoid or occasionally
cylindrical in species with salver-shaped corolla, glabrous or
seldom pilose, 2-celled, each cell with 2-ovules, occasionally
1-celled, 4-ovuled. There are two styles, these are totally free
or slightly united at the base, each style is divided into 2 branch-
es; the stigmas are long, terete, filiform or slightly clavate.
The ovules are erect, anatropous, apotropous and spring from
the inner angle of each cell or from the base of the ovary.

Fruit. The fruit is a capsule, globose or ovoid, and
generally opens with 4 valves. It is 4-seeded or by abortion less
to 1-seeded; in the latter case it is sometimes more or less oblique
and only 3 or 2-valved. The seeds are small, smooth or minutely
verrucose, generally of brown or black colour; the cotyledons
are almost flat, the radicle is incurved, the endosperm is cartila-
ginous and surrounds the embryo.

H a 11 i e r 1 ) in his quot;Versuch einer natürlichen Gliederung
der Convolvulaceen etc.quot; places the genus Evolvulus in the
Dicranostyleae just as Meissner did. As to the limits in respect
to the other genera of this group they are very distinct. The two

styles, both 2-cleft, make an interchange with other genera
practically impossible. H a 11 i e r justly speaks of quot;die grosse,
schon von der Natur vorzüglich abgegrenzte, leicht an ihren 2
gabelspaltigen Griffeln kenntliche Gattung Evolvulus.quot;

According to H a 11 i e r there exists a distinct relationship to
various other genera, to Stylisma, to which the pollen shows a
resemblance; further to Seddera. Cressa, Cladostigma and Hilde-
brandtia, all of which have the small flowers in common with
Evolvulus and, moreover, possess the same glabrous filaments,
scarcely enlarged at the base, and seldom provided with a tooth
on either side. Anatomical resemblance to Stylisma and Bonamia
also exists.

If we compare the representatives of the genus Evolvulus,
as to the inflorescence, with the average type of the family
Convolvulaceae, that is the type with dichasial pedunculate in-
florescences in the leafaxils, spread over the stem, then it appears
that the species of the subsection Pedunculati of the Alsinoidei
show the greatest resemblance hereto. The development of the
peduncles may differ very much; they are often longer, but often
also shorter than the leaves. In a few species, possessing mostly
a peduncle, this may completely disappear by way of exception.
In the subsection Epedunculati immediately connected with the
Pedunculati this absence of the peduncle is the rule. Here too
the flowers appear spread over the stem, they are direct axillary,
and usually provided with a short pedicel. If we consider the
corolla of the Pedunculati, then it appears that this is rotate in
most cases and provided with a very short tube. In the majority
of the Epedunculati too the rotate corolla is found, but in a few
species the tube is longer and a funnel-shaped or even a hypo-
crateriform corolla appears; the former in E. frankenioides and
two closely allied species, viz. E. Riedeln and E. villosissimus,
the latter in E. audgenius and a number of species closely related
to it, viz. E. macroblepharis, barbatus, cressoides, ranflorus and
cardiophyllus. The two subsections of the Alsinoidei show a
great similarity in habit.

doubtedly closely related to each other. The distinction of the
species causes great difficulties. The greater part group them-
selves immediately round E. alsinoides and the South American
E. tenuis.

Next to the Pedunculati is the section Linoidei, but the majority
of the species differ in the stiff, erect habit. This group, which
undoubtedly contains a number of very closely allied species,
was already distinguished by Meissner next to the Alsinoidei,
and he was certainly right in doing so. This section is well
defined by a group of characteristics some of which are the
habit, the frequent deeply-lobed rotate corolla, the frequent
obtuse sepals.

The section Paniculati might be united with the Linoidei, but
it is better to keep them separate in order not to disturb the unity
of the latter to much.

Next to the Epedunculati there is a section, that of the Pas-
serinoidei, which is also characterized by the axillary flowers
with rotate corolla, but the habit is generally different here too.
The Brazilian representatives of this section we may divide into
two groups, the one with plants possessing a not or slightly
lobed corolla, viz. E. Maximiliani, passerinoides, jacobinus,
Luetzelburgii, scoparioides and thymiflorus, the other with a
distinctly 5-lobed corolla, E. genistoides, diosmoides, daphnoides,
phyllanthoides and latifolius. Each group possesses a number of
closely related species. There are two species connected with the
former viz. E. Weberbaueri and E. peruvianus, both of which
are limited to Peru. Besides these inhabitants of Continental
South America three species appear on the West Indian Islands,
E. arbuscula, bahamensis and squamosus, which are undoubtedly
closely allied to each other, also however showing a great degree
of similarity with the Brazilian forms. They are low shrubs with
an erect habit and generally small leaves.

Meissner combines the groups treated thus far, under the
name of Sparsiflori, in contradistinction to the Spicati, which
show a strong specialization in the inflorescence. We may
distinguish three sections here, all characterized by the fact that

the flowers are approximate and sessile at the end of the stems
and the branches, whilst moreover the corolla is salver- to funnel-
shaped, which characteristic is also found in some species of the
Epedunculati.

The section nearest to the Sparsiflori is that of the Phyl-
lostachyi, with flowers all of which are situated in the axils of
normal leaves, closely approximate at the end of stems and
branches. Among the representatives of this group there is one
showing a funnel-shaped corolla with a rather short tube, viz.
E. Glaziovii: the others mostly show more distinctly developed
tubes. The species are rather easily distinguished from one
another.

In the Involucrati the undermost bracts in the inflorescence
are still leafy, but towards the top appear smaller and narrower
ones.

Finally in the well defined section of Lagopodini all bracts
have become small and narrow, the inflorescence is more
distinctly separated than in the two preceding ones, the corolla
is distinctly salver-shaped, whilst, as a further specialization, the
leaf-bases are decurrent on the stems. This characteristic
especially is very singular and unique in the family.

All species of the genus Evolvulus are found in America, only
two of these extend their area over the Old World. One, the
polymorphous E. alsinoides, covers the greatest area and is also
found in Africa, in South and South-East Asia, on the islands
between Asia and Australia as well as in the latter continent.
In America the species reaches its northerly limits in the South
of the United States and is further found in Central America,
on the West Indian Islands and in the north-western states of
South America, in Colombia, Venezuela, Guiana and the northern
part of the Brazilian state of Amazonas; the most northern
localities in West Africa are the Cape Verde Islands and
Senegal, and Nubia in East Africa. In the south the area extends
■to the Transvaal and Natal, further the species is found on

Madagascar and neighbouring islands, and on Socotra. The
African area is continued to Jemen in Arabia. Further it occurs
in the whole of British India to the Himalayas, in Ceylon, in
Further India, the Malay Peninsula, in Indo-China and reaches
its northern limit in China at 31° N. L. (Hupeh). The Philip-
pines and Formosa, besides the islands of the Netherlands Indies
connect the area in Asia with that of Australia. In West
Australia the species is known only in Kimberley and the N. W.
Division, in the east it even reaches New South Wales. In
Oceania it is found on New Caledonia and the Fiji Islands.

The second species, E. nummularius, also found in the Old
World, seems to have been introduced into British India in
recent times; I am not sure whether its appearance in Africa is
also due to a similar recent introduction. In the southern U. S.
and Argentina we find E. arizonicus closely allied to E. alsinoides,
whilst the closely related E. tenuis is found in South America.
The latter species with its various subspecies inhabits a great
part of the South American continent. Of the remaining
Alsinoidei—Pedunculati, E. filipes and E. glaber extend over
great parts of tropical and subtropical America. Besides these
species a number are found in the west of South America as
well as in Brazil and Paraguay, each covering a much smaller
area; to the former belong the species, undoubtedly closely allied,
E. villosus, helianthemoides, piurensis, boliviensis, incanus and
bogotensis whilst E. magnus, argyreus, Herrerae, and Fieldii,
which presumably closely belong to each other also inhabit the
Andine region; to the second the closely alhed E. linarioides,
saxifragus and vimineus which are also related to E. tenuis, and
further the group to which E. [lexuosus and anagalloides belong.
To this latter group also belongs the W. Indian E. Grisebachii.

In the Alsinoidei—Epedunculati E. sericeus and E. nummu-
larius are the species which cover the greatest area, the former
appearing with its different varieties from the Southern United
States of America to Argentina, and also on the West Indian
Islands; the latter occupies about the same area in America but
however does not reach so far north and south.

Of the remaining species belonging to this subsection, most
inhabit a more limited area; of all Evolvulus species E. pilosus
is the one which is found most northerly in America to Montana
and N. Dakota, it is limited to the United States. Three species
very closely allied to E. senceus, viz. E. rotundifolius. prostratus
and Purpusii are found in Mexico; a fourth species E. arenicola,
has so far been collected only on the Venezuelan island Margari-
ta. In contradistinction to the Pedunculati only two of the species
with limited area of this subsection are found in the west of South
America, viz. E. cardiophyllus and E. simplex. The latter of
these two was originally considered as an endemic form of the
Galapagos Islands, but, however, was also met with in Peru in
later times. Several other species with a small area occur in
Brazil. Here belong E. cordatus. speciosus, gnaphalioides and
chrysotrichos. The related E. Hallierii was found in Mexico.
Very peculiar is the distribution of E. Pohlii, which species occurs
in central Brazil and in Mexico. Of E. villosissimus, frankenioides
and Riedelii the first is confined to Venezuela, the second has
been collected in Venezuela, but also occurs in Bolivia and in
N. E. and C. Brazil, the third was only found in Sâo Paulo.
Further E. aurigenius and allied species specialized as concerns
the possession of a well-developed corolla tube belong here;
all, except the above-mentioned E. cardiophyllus are confined to
the central and southern parts of Brazil. The West Indian
Islands contain three closely allied species of this subsection,
E. Bracei, minimus and siliceus.

The Linoidei are confined to Brazil and neighbouring Paraguay
and Bolivia; only one species, E. elegans, also occurs in
Venezuela.

The Passerinoidei ate Brazilian for the greater part (16 spe-
cies, 11 Brazilian). Two species, E. Weberbaueri and E. peru-
vianas, occur in Peru; three very closely allied, E. arbuscula,
squamosus and bahamensis are found on the West Indian Islands,
the first in Cuba, Haiti and Jamaica, the two others on the

Bahamas. Of the Brazilian species, E. latifolius is found as far
as in Paraguay and North Argentina.

Finally the three sections with distinct spike-like inflorescences;
of the 15 species composing the Phyllostachyi, there are 13
exclusively occurring in Brazil, and inhabit limited areas there;
one species also extends its area as far as Paraguay viz. E.
Chamaepitys, whilst E. alopecuroides also occurs in Venezuela.

The only species of the Involucrati, E. glomeratus is found in
Brazil and the neighbouring states Bolivia, Paraguay, Uruguay
and Argentina. One of the sub-species is also known from
British-Guiana.

Thus we see from the above summary that some of the species
belonging to the Alsinoidei—Pedunculati and Epedunculati have
the widest distribution. The more specialized forms of the
remaining sections have a much smaller area in most cases; the
genus has attained its greatest degree of development in Brazil;
a centre of development also seems to lie in the western part
of South America, whilst the W. Indies and Mexico also contain
some endemic forms. One peculiar feature is that some species
occurring in Central and Southern Brazil, are also found in Vene-
zuela. The similarity between Mexico and the Andine region
is but slight, yet there are some species to be indicated, besides
those inhabiting a great part of America, which occur both in
Mexico and Colombia, viz. E. ovatus and E. cardiophyllus.

E. alsinoides is applied in the native medicine in British India,
it is used there as a febrifuge and tonic. W a 11, in his Dictionary
of the Economic Products of India III (1890), derives from
Ainslie that the plant is used in bowel complaints; according to

Dynock it was believed to possess the power of promoting con-
ception. Watt informs further the use of the roots in inter-
mittent fever of children, quot;the leaves are made into cigarettes
and smoked in chronic bronchitis and asthmaquot;. quot;The plant is
astringent, useful in internal haemorrhagesquot;, quot;Mohammedan
physicians believe that this plant has the power of strengthening
the brain and memoryquot;.

In the Tanganyika Territory a medicine for sores is made
from the pounded leaves, according to Graham (on a label
in herb. Kew).

According to a communication of D e c a r y which I found
on a label in herb. Paris E. nummularius is also used in cases
of haemorrhage in Madagascar.

Annual or perennial herbs, undershrubs or shrubs; stems
prostrate, ascending or erect, never twining. Leaves mostly small,
simple, entire. Flowers hermaphroditic, regular, in axillary, pe-
dunculate, several to 1-flowered dichasia or in few-flowered
groups or solitary, petiolate or sessile in the leaf-axils, or
aggregate at the ends of the stems and the branches in spikes
or heads. Sepals 5, free, equal or subequal, acuminate, acute or
obtuse. Corolla rotate, funnel or salver-shaped, generally small.

purple, blue or white, rarely yellow, the limb plicate, subentire
or obscurely to distinctly 5-lobed, the lobes outside with a pilose
band. Stamens 5, filaments filiform, inserted on the corolla, at
the mouth of the tube, glabrous, occasionally with a tooth at both
sides of the base; anthers ovate to oblong or linear. Ovary
globular, ovoid or occasionally cylindrical, glabrous or occasional-
ly pilose, 2-celled, each cell with 2 ovules, occasionally 1-celled,
4-ovuled; styles 2, shghtly united at the base or totally free,
each style 2-cleft; stigmas long, terete, filiform or slightly clavate.
Capsule globose or ovoid, 4-valved, 4—1-seeded, in the latter
case occasionally oblique and 3- or 2-valved. Seeds small, smooth
or minutely verrucose; cotyledons nearly flat, radicle incurved.

Of the genera which must be united with Evolvulus, Camdenia
was described by Scopoli in 1777. This author based the genus
on the Visnu of the Hortus Malabaricus but however mentioned
no species. One of the British Indian forms of E. alsinoides L.
is meant here. Cladostyles H.B.K., based on Cladostyles panicu-
latus, was already recognized by Sprengel as an Evolvulus.
Meriana based by Vellozo on Meriana procumbens, the original
material of which I did not see, but, however, the description
and the plate in the Flora Fluminensis, is without doubt identical
with E. pusillus Choisy. Plesilia Raf. has been based on an
incomplete specimen from New Jersey, Evolvulus cuneifolius
Raf., and was created by the author under reserve, as the
corolla and the stamens are not known. I am not quite sure if
this genus belongs here.

Finally Leucomalla lanuginosa Phil., the type species of
Philippi's Leucomalla, must also be considered as belonging to
the genus Evolvulus, according to Bentham amp; Hooker's Genera
Plantarum. It is identic with E. sericeus Sw. var. falcatus
(Griseb.) v. Ooststr.

1. Flowers pedunculate, in few- to 1-flowered dichasia, or peduncle absent,

Perennials, rarely annuals, very rarely undershrubs or shrubs,
prostrate, ascending or erect. Leaves and hairiness very variable.
Flowers in pedunculate, axillary, few—1-flowered dichasia, or
peduncle absent; in the latter case the flowers are situated in the
leaf-axils, generally pedicellate, rarely sessile, solitary or in few-
flowered groups of dichasial character. Corolla rotate, funnel-
shaped or salver-shaped with subentire, superficially lobed or
distinctly lobed limb.

I united the sections Alsinoidei and Anagalloidei, distinguished
by Meissner, under the name of the former. The difference in
the development of the peduncle in the two sections appears only
of a gradual character and a separation in two distinct sections
is not necessary. The species with developed peduncle I unite to
the subsect. Pedunculati; the non-pedunculate ones to the subsect.
Epedunculati. I could not maintain Meissner's name Anagalloidei
for the latter, because E. anagalloides, after which species the
author named the section, belongs to the Pedunculati.

Peduncle developed, longer or shorter than the subtending leaf, very rarely
absent. Corolla rotate to widely funnel-shaped. Subsect. 1. Pedunculati, p. 22.

an often hgnescent root, prostrate or ascending, slender, variable
in length, 12—50 cm, villose with appressed and patent hairs.
Leaves oblong, elliptic or spathulate, the broadest part in or
above the middle, obtuse or sometimes slightly emarginate at
the apex, mucronulate, rounded at the base or attenuate into
the short petiole, 7—20 (—25) mm long, 3—10 mm broad, 1.5—
2.5 (—3) times as long as broad, more or less densely appressed-
pilose on both sides, sometimes glabrous above. Peduncles fili-

Distribution: British India, Indo China, China,
Philippines, Netherlands Indies; also in Madagascar and trop.
E. Africa.

The form on which Linnaeus based this species is the common
British Indian form, spread throughout S. E. Asia but also occur-
ring in the Philippines, the Netherlands Indies, Madagascar and
tropical E. Africa. Beside this form a large number of varieties
occurs, both in the tropical and subtropical parts of the Old
World and in America. These varieties are however very difficult
to separate. Everywhere transitional forms occur and often it
is quite impossible to say to what variety a specimen belongs.
Below, at the end of the species the list of the collectors' numbers
may be found. As far as possible the number of the var. is placed
between the brackets, before the abbreviations of the different
herbaria. Transitional forms are known between the typical form
and var. hirsutus, linifolius, decumbens. Specimens with narrow,
more remote leaves much resemble var. debilis (indicated in the
list of collectors' numbers with ta).

by the slender stems, the less dense indumentum and the smaller
leaves.

Much resembling the typical form, the leaves however often
more ovate, the broadest part below the middle. Hairs on the
stems generally patent.

Habit much resembling that of the typical form. Stems few
or several, prostrate or ascending, slender, variable in length,

villose. Leaves ovate, oblong or elliptic, sparsely or densely-

In Arizona occur plants with a much denser indûment than
in the normal Mexican form (Sierra Tucson, Pringle s. n., Apr.
25, 1884; id. Parish 170). Small specimens of the var. acapulcen-
sis with rather small leaves approach microphyllus (Shannon
3608). Transitional forms to var. debilis exist.

Stems erect in the first year, later often prostrate, rather stiff,
to 40 cm long, pilose with appressed and patent hairs. Leaves
lanceolate, oblong-lanceolate or linear-lanceolate, occasionally
broader, attenuate towards both ends, acute or obtusish at the
apex, generally acute at the base, the middle-sized leaves 20—40
mm long and 5—10-mm broad, the upper ones often much smal-
ler, more or less densely appressed-pilose on both sides. Pe-
duncles, especially the upper ones, generally exceeding the leaves,
l_few-f lowered, stiff, erecto-patent; bracteoles subulate to
lanceolate, 2—4 mm; pedicels longer than the calyx. Sepals
lanceolate, acuminate, about 3 mm long. Corolla about 7 mm in
diam.

Distribution: Africa, from the Cape Verde Islands,
Senegambia and Nubia southward to Angola, Transvaal, Natal;
Madagascar;. Yemen.

Typical specimens of the above var. appear to be limited to
Africa. Densely hairy forms with brownish hairs and small leaves
pass into var. Wallichii. E. azureus Vahl is a form with small
leaves. American specimens cited by many authors under the
name E. linifolius L. belong for the greater part to var. debilis,
Australian specimens to var. decumbens. The literature on E.
linifolius L. may be found above, but only citations of literature
on African specimens really belong here.

Stems several, prostrate or ascending, 20—40 cm long, quite
glabrous or sparsely pilose with appressed and patent hairs.
Leaves in the type oblanceolate to oblanceolate-oblong, obtuse

and mucronulate at the apex, attenuate into the petiole, 8—13 mm
long, 3.5—5 mm broad, 2—2.5 times as long as broad, in other
specimens linear or linear-lanceolate, acute or acuminate at the
apex, acute at the base, 7—16 mm long, 1—2.5 mm broad, 5—7
times as long as broad, quite glabrous or sparsely pilose beneath
on the midrib; midrib and lateral nerves prominent beneath.
Peduncles glabrous, exceeding the leaves, 10—20 mm long;
bracteoles subulate, 1.5—2 mm, pedicels as long as to twice as
long as the calyx. Sepals lanceolate, acute or acuminate, 2—3
mm long, quite glabrous. Corolla small, little exceeding the sepals,
white or pale-violet. Filaments ± 1.5 times as long as the oblong
anthers. Ovary glabrous, globular.

Distribution: Africa, hitherto only found in Cameroon,
Belgian Congo, the type from Natal.

in Lecomte, Fl. Gén. de I'lndo-Chine IV, fase. 3 (1915) p. 304,
quoad nomen.

Stems several from a thick woody base, prostrate or ascending,
2—15 cm long, covered with long appressed and patent brown
or ferrugineous hairs. Leaves lanceolate, oblong or narrow-
elliptic, acute or obtusish at the apex, rounded or acutish at the
base, 4—6 mm long, 1.5—3 mm broad, densely villose on both
sides like the stems. Peduncles short, not or little exceeding the
leaves; bracteoles linear; pedicels as long as or longer than the
calyx. Sepals lanceolate, acuminate, 3 mm long. Corolla 10 mm
in diam.

Closely related to densely hairy African specimens of var.
linifolius. Transitional forms to this var. occur, e.g. specimens
collected by Royle in N. W. India.

the species.

met with, which possess a greyish shining closely appressed in-
dûment, much resembling that of var. javanicas. (Indicated in
the list of collectors' numbers with 12a).

E. lanceaefolius Span, is intermediate between the typical form
and var. decumbens.

Specimens belonging to var. decumbens are often met with in
the herbaria and in the literature under the name E. linifolius L.

E. javanicus Blume, Bijdr. Fl. Ned. Ind. (1825) p. 724; Koor-
ders, Exkurs. fl. von Java III (1912) p. 110.

Stems several from a stout woody base with perpendicular
root, erect or ascending, rather slender, 6—20 cm long, densely
appressed-pilose with fulvous, later greyish, more or less shining
hairs; internodes 3—5 mm. Leaves linear or linear-lanceolate,
densely appressed-pilose hke the stems, erect or erecto-patent,
acute or acuminate at the apex, attenuate to the base, often
enrolled, 4—11 mm long, 1—2.5 mm broad, 4—7 times as long
as broad. Peduncles short, 2—5 mm, pilose like the stems;
bracteoles subulate, 1 mm; pedicels as long as or commonly much
longer than the calyx, to 7 mm. Sepals lanceolate, acuminate, 2.5
—3 mm, appressed-pilose. Corolla rotate, 8—9 mm in diam.

Koorders I.e. does not believe that Blume's specimens were
collected on Mount Gedeh (Java). They are fully identical with
specimens from the Moluccas. Transitional forms to var. decum-
bens exist (Philippine Islands, Indo-China, Australia). Also to
var. philippinensis.

Perennial or suffruticose. Stems erect or ascending, to 50 cm
high, few- or much-branched with erecto-patent branches. Indû-
ment of stems and leaves variable, generally consisting of short
hairs, sparse to dense. Leaves variable in form and size,

Prince zu Wied-Neuwied (Br, G); without precise locahty, A. de St.-Hilaire
B\ 1479 (P).

Meissner who did not know the type of E. tenuis Mart,
described a var. obtusatus. based on specimens collected by the
Prince zu Wied-Neuwied between Valos and Tamburil, Minas
Geraes, Brazil, and on others collected by Funck (260) near
Cumana, Venezuela. The former totally agree with the type
of E. tenuis Mart, in the Kew Herbarium, the latter belong to
the ssp. longifalius (Choisy). Other specimens which were also
collected by the Prince zu Wied-Neuwied in the same locality,
were incorrectly ranged under E. villosus by Nees and Martius
and again by Meissner. They fully correspond with the above-
mentioned specimens.

This var. has the habit of the typical form, the whole plant
is however densely fulvous to ferrugineous tomentose, on the
stems there are also longer spreading hairs. Leaf shape as in
the typical form.

A specimen collected by Ule (452), Brazil, Goyaz, Serra
Dourada (P, R), probably belongs here. The indumentum is
much like that of the Sellow plant, the leaves are narrower,
lanceolate or narrow-ovate-lanceolate, 18—28 mm long and 5—9
mm broad, 2.5—3.5 times as long as broad; moreover the leaves
are more remote.

Leaves ovate, ovate-oblong or broad-ovate to nearly orbicular,
the upper ones often narrower, ovate-lanceolate, acute, obtusish
or broadly rounded at the apex, mucronulate, rounded at the
base or subcordate, 9—20 mm long, 3.5—16 mm broad, (1—)

tomentose on both sides with loosely appressed hght brown or
grey hairs, often longer hairs along the leaf-margin. Midrib and

glabrescent leaves, pale; reticulate nervation more or less visible.
Stems covered with short loosely appressed hairs, mixed with
long patent ones.

Hall. f. (B, L, S).

The type of E. longifolms Choisy is a very slightly pilose
specimen, just as the type of E. columbianus Meissn. For a
discussion of E. tenuis Mart. var. obtusatus Meissn. see under
ssp. eu-tenuis. E. bocasanus Britton is based on a rather tomen-
tose specimen with distinct prominent reticulate nervules. Some
specimens of the above ssp., for example Broadway 238, approach
the ssp. sencatus and of this especially the specimen Padre
Corneho 97. Th. Herzog 1129, the type of E. columbianus
Meissn. var incana Hall, f., has the stems and leaves covered
with a dense tomentum mixed with spreading hairs.

Leaves oblong, narrow-oblong or hnear-oblong, occasionally
elliptic, the broadest part in or near the middle; very rarely
linear-lanceolate, and approaching the form of those of the ssp.
longifolius. Pubescence always dense, tomentose, especially on
the stems and the lower surface of the leaves, colour of the
indumentum greyish to fulvous. Midrib and 3—5 pairs of lateral
nerves more or less visible in large leaves, tertiary nervation
obsolete.

The form and size of the leaves of this ssp. are rather variable;
the oblong and narrow-oblong leaves as occur in the type and
several other specimens have a length of 10—20 mm and a
breadth of 5—8 mm, they are 2—3.5 times as long as broad.
Linear-oblong leaves attain a length of 30 mm or more and are
to 5.5 times as long as broad (e.g. Vogl 93). Specimens with
very small leaves, 8—12 mm long and 2.5—6 mm broad are
Pennell 1865, 2876, Dawe 329 and Jahn 655. Transitional forms
to the ssp. longifolius occur, e.g. the numbers Padre Cornelio 97
and Curran amp; Haman 844. A specimen from Trinidad, Britton
503 probably also belongs here. It has the leaves elliptic, 15—16
mm long, 7—8 mm broad. Britton and Hazen 1695 much
resembles it. Schlechtendal's E. albifloms presumably belongs
here, but I did not see the type-specimen.

Leaves lanceolate to linear-lanceolate or occasionally linear-
oblong acute or acutish at the apex and at the base, sometimes
rounded at the base, 8-18 (-20) mm long, 2.5-4 (-6) mm
broad, (3_) 4—4.5 times as long as broad, sparsely pilose on

This species is rather variable in habit and size, typical
specimens are erect in the first year, later mostly more ascending.
The height of the plants may differ very much; from very small,
hardly 5 cm to 40 cm. The hairiness is generally sparse, closely
appressed, sometimes however with more spreading hairs. The
size of the leaves is also rather variable. In robust specimens they
may attain a length of 2.5 cm, they are often much smaller, weak
specimens sometimes show leaves only a few mm long. The
peduncles are generally filiform, longer or much longer than the
subtending leaves, sometimes they are shorter. Transitions occur
everywhere. Sharply defined forms are difficult to distinguish.
The types of the var. ^ gracillimus and of the var. a abbreviatus,
both described by Meissn., differ fairly much from the typical
specimens of the species. The former is characterized by the
very wide extending branches and the long filiform peduncles,
which are situated in the axils of very small, subulate leaves,
1—3 mm long; the latter chiefly differs in the short peduncles.

Numerous transitions between the varieties and the species
however occur, so that I deem it advisable to unite them with
this.

E. nanus Meissn. is to be considered as a low form of
E. filipes, with small leaves and short peduncles. The specimen-s
Meissner distinguished as E. exilis are low weak plants of the
typical form with small narrow leaves and slender peduncles.
The plants considered by Chodat and Hassler as var. exilis are
partly wholly identical with the type of the species, partly tran-
sitions to the weak small plants, which Meissner called E. exilis.
Regnell III, 1913^ unites E. exilis also with the species. E.
saxifragus Mart. var. paraensis Meissn. is represented by plants
which are fairly robust, much branched at the base with ascending
branches with rather spreading hairs. Some specimens, viz. de
St.-Hilaire Bi, 1486 and 1541bis show flowers with a diameter
of about 7 mm, the pedicels attain a length of 10 mm. In other
respects, also in the size of the sepals, they agree with the
typical E. filipes, the larger corolla and the longer pedicels
however remind us of E. saxifragus.

Perennial. Stems few or several, herbaceous, prostrate, occa-
sionally rooting at the basal nodes, terete, slender, 5—30 cm
long, sparsely beset with short, stiff, appressed hairs, glabrescent.
Leaves shortly petioled, secund, oblong, narrow-oblong, oblong-
lanceolate or oblanceolate, rounded at the apex, acute or obtusish
at the base, 7—16 mm long, 2—5 mm broad, glabrous on both
sides or sparsely appressed-pilose beneath; midrib prominent
beneath, lateral nerves indistinct or the basal pair visible beneath.
Peduncles filiform, directed upwards, 5—15 mm long, those at
the middle of the stem shorter than or as long as the subtending
leaf, the upper ones exceeding this, 1—^2-flowered, sparsely

appressed-pilose like the stems; pedicels longer than the calyx,
6_10 (_18) mm, filiform; bracteoles linear or narrow-lanceo-
late, acute or obtusish, glabrous, 2—3.5 mm long. Sepals ovate-
lanceolate to oblong-lanceolate, acute, sparsely ciliate, 2.5—3 mm
long. Corolla blue or white, rotate, the tube very short, the limb
10—12 mm in diam., superficially 5-lobed. Filaments as long as
the oblong anthers. Ovary ovoid, glabrous. Capsule as long as
the sepals, globular, 4-valved. 4-seeded. Seeds dark-brown,
smooth.

The description Meissner gives of this species relates to the
specimen Langsdorff and Riedel. The specimens Warming, also
cited by Meissner, partly represent a variety, which I name var.
Warmingii.

Stems, lower surface of the leaves, peduncles, pedicels,
bracteoles and sepals much more pilose than in the type, with
soft, loosely appressed or spreading hairs; upper leaf-surface
glabrous or sparsely pilose. Peduncles 1—2 or occasionally 3-
flowered. Sepals up to 4 mm long.

No doubt closely related to E. alsinoides L.^and E. tenuis
Mart., but different in the much larger corolla. In Argentina
occur specimens which so much resemble the Arizona ones that
it is impossible to draw a distinct line between them. For the
time being I wish to place them here. It is not impossible that
similar climatological circumstances gave rise to the two forms
which so much resemble each other; in Arizona beside the forms

of E. alsinoides which occur in that country, in Argentina beside
E. tenuis, which perhaps only represents a form of E. alsinoides
also Both the Arizona specimens and the Argentina ones are
rather variable in habit, size, form of the leaves and indumentum.
Specimens from Jujuy, elevat. to 3800 m, are small, densely hair/
and have large, intensively blue corollas.

from the former, the similarity with the latter is greater, although
distinct differences may also be given here.

The specimens existing in the herbarium Brussels under

The shape of the leaves may show a rather great variability.
In most cases they are fairly broad and obtuse, sometimes they
are narrower, distinctly oblong, as example I mention Sintenis
599. Wullschlaegel 927 is very narrow-leaved. Now and then

emarginate leaves occur, which are mostly broad, almost
orbicular. The length of the peduncle is rather variable. As an
exception it is almost lacking. Consequently its being mistaken
for E. nummularius L. which moreover often resembles this
species in leaf-form, is explainable. The form and size of the
corolla and also the typical hairiness with short patent curved
hairs are however characteristics by which E. nummularius is
easy to distinguish from E. glaber. On the Islands Aruba.
Curasao and Bonaire a densely hairy form occurs.

Meissner incorrectly ranges this species with the Passerinoidei.
Shows great resemblance in habit to E. cordatus. differs however
from this species among others by the much larger corolla, the
larger sepals and the thicker pedicels. Meissner gives the
diameter of the corolla as quot;6—8 lin.quot;, the specimens collected

by Ule (Ule 7408) show corollas with a diameter of about 3 cm,
the largest known in the genus.

Perennial herb. Stems several from a perpendicular root,
prostrate, simple or somewhat branched below, 10—35 cm long,
densely patently villose with long brown hairs, especially the
younger parts, densely leafy near the apex, the leaves patent,
secund or directed towards the apex and more or less appressed
to the stems; internodes at the middle of the stems 5—7 mm

The Linnean Herbarium contains a sheet with 3 specimens of
E. nummularius L., ex herb. Banks, and 1 specimen of E. glaber
Spreng, collected by P. Browne.

The specimens which represent the var. emarginatus Meissn.
belong to E. Pohlii Meissn. The var. grandifolia Hoehne is based

on a specimen with large leaves, such specimens frequently occur
in a fertile, favourable habitat.

The African E. dichondroides Oliv. fully agrees with typical
E. nummularius. About the capsule of the type specimen of E.
dichondroides, the collector, Mr. }. A. Grant says: quot;after the
flower falls off, the seed-vessel turns into the ground, like the
Arachis hypogea, and propagatesquot;.

The length of the hairs in this species is rather variable as
also is their colour. Specimens cited by Small as belonging to his
E. mollis are partly closely appressed-pilose, but so many
intermediate specimens occur between these and typical E. pilosus
that it is impossible to keep the species separate.

the indûment is greyish or whitish in youth), oblong, oblong-
lanceolate, narrow-ovate or ovate, the basal ones often the
broadest, acute or obtusish and submucronulate at the apex, acute
or rounded at the base, 8-16 mm long, the middle ones 4—7, the
lower ones occasionally up to 9 mm broad; midrib and basal
lateral nerves slightly impressed above. Flowers axillary, solitary.

peduncle very short, villose or none; pedicels 1.5—3 mm long,
erect, later reflexed, villose; bracteoles linear, 3 mm long, villose
with spreading hairs. Sepals slightly unequal, the outer ones

The type has an erect habit, just as the specimens collected by
Warming and by Balansa (1173). The leaves of the type are
about oblong, the broadest part in the middle, they are rather
obtuse, mucronulate, erect, the lower ones are slightly broader.
The specimen Warming has the same leaves, only more acute;
the specimen Balansa 1173 has narrow-ovate to ovate, acute
leaves, the largest part below the middle. Other specimens, for
example Lôfgren, are more ascending and more branched and so
is the type of E. guaraniticus. which in hairiness and leaf-shape
much resembles Balansa 1173. Identical with the type of E.
guaraniticus is the specimen Fiebrig 5235.

Mexico, Central America, West Indies, South America, from
Colombia to northern Argentina 3).

Typical specimens of E. sericeus Sw. are erect or ascending,
with narrow erect leaves; typical E. holosericeus HBK. is
prostrate, with distichous leaves. Beside the typical form of
E. sericeus, Persooni) distinguished a var. Commersoni, based
on specimens collected by Commerson near Montevideo,
Uruguay (= var. latior Meissn. 2)). These specimens have the
stems generally shorter, the leaves are more patent and are often
broader, often less than four times as long as broad. It is
impossible however to draw a distinct line between the two.
On the other hand there are also specimens which pass into the
typical holosericeus. I presume that the forms are due to dif-
ferences in habitat when occurring in a closed or more open
vegetation. An examination on the habitats themselves may lead
to a solution here. All specimens which have the leaves not
distinctly in two rows I reckon to the typical E. sericeus.

Convolvulus proliferus Vahl is based on a specimen, misformed
by a gall; the leaves are partly closely approximate and form an
almost globular body at the top of the stems.

possess large corollas, up to 15 mm in diam., the sepals to 5—6
mm long. Such large corollas also occur in the f. pedunculatus

Both in the typical specimens and in those which correspond
to Persoon's var. Commersoni, as well as in the transitional
forms, the following distinctions may be made:

b.nbsp;a form with leaves not glabrous above, appressed-sericeo-
villose on both sides, equally dense on both sides or less
dense above than beneath; transitions to a. occur.

The type has the leaves rather broad, ovate-oblong to elliptic,
obtuse. Also specimens often occur with longer and narrower
leaves; to the latter belongs House's E. Wilcoxiana. Numerous
transitions exist however and a separation in one or more forms
is not possible. There are some remarkable specimens with
distinctly distichous, elliptic leaves, e.g. Pringle 6720, Conzatti
and Gonzalez 441, both from Oaxaca.

Besides the typical E. Purpusii there is also a form with leaves
hairy on the upper surface. It is possible we have here a
parallelism to what also happens in E. sericeus Sw. and in the
var. holosericeus and discolor of that species, so that we can also
distinguish here the following two forms:

The specimens I have as yet seen of the form b. further
differed to a very slight extent from the type of a.; the leaves
are ovate or oblong and are somewhat larger, 6—11 (—17) mm
long and 3—5 (—6.5) mm broad.

To form b. belongs: C. A. Purpus 5443, San Luis Potosi,
Minas de San Rafael, Agua del Medio, July 1911 (B, Gr,
Gro, US).

A specimen of erect habit with leaves hairy on both sides, not
distinctly distichous, narrow-oblong, acute or obtuse, mucron-
ulate, 13—20 mm long, 3—4 times as long as broad and with
longer internodes, 8—15 mm long, probably also belongs here.
I suppose that the typical form of E. Purpusii stands in the same
relation to this specimen as the var. holosericeus of E. sericeus
to the typical specimens of that species. The above specimen was

collected by H. W. von Rozynski (457a), Mexico, Tamaulipas.

Perennial. Stems several from a woody base, prostrate, simple,
5—10 cm long, densely sericeo-villose, fulvous; internodes about
2 mm. Leaves distichous or secund, subsessile, oblong-lanceolate
or ovate-oblong, acute at the apex, rounded or acutish at the
base, 6—9 mm long, 2.5—3.5 mm broad. 2.5—3 times as long

greyish. Midrib more or less visible beneath. Flowers axillary,
solitary, peduncle none; pedicels none or very short, to 2 mm
long; bracteoles minute. Sepals lanceolate, acuminate, 3—3.5 mm
long, sericeo-villose like stems and leaves. Corolla rotate, pale-
blue, 3 times as long as the calyx, limb about 12 mm in diam.,
almost entire. quot;Ovary glabrous, containing 4 dull brown seedsquot;.

The material that I had at my disposal, did not allow of a
closer examination of the corolla, stamens and pistil. Closely
related to E. sericeus Sw. var. holosericeus (HBK.) but different
in the kind of the indumentum.

covered with a generally dense, short tomentum, mixed with
longer, appressed hairs, but not densely sericeo-villose. Midrib
and basal lateral nerves more or less prominent beneath, impres-
sed at the base above. Flowers axillary, solitary or in clusters
of 2—5, over the whole length of the stems; peduncle none;
pedicels up to 3 mm long; bracteoles linear or hnear-lanceolate,
2—2.5 mm long. Sepals equal, from a lanceolate base long linear-
acuminate, shortly tomentose and long villose, (4—) 5—6 mm

Closely related to E. Riedelii Meissn. In Riedelii the
sericeo-villose hairs prevail and the tomentum is not much
developed or not at all, whilst in E. frankenioides the tomentose
hairiness is more conspicuous; this is especially the case m the
leaves. Choisy distinguished a var. strictas which Meissner justly
united with the species. The var. glabrescens Meissn., based on
a specimen collected by the Prince zu Wied-Neuwied in Brazil,
state Bahia, near the Mucuri River, must be considered as a
variety of E. jacobinus. The var. rariflorus Meissn. was based
on the specimens Burchell 7121 and Regnell III 189, the former
represents a distinct species, which I name E. rariflorus. the latter
belongs to E. Riedelii Meissn.

Stems stouter than in the typical form, leaves larger, broad-

Undershrubs or shrubs, generally erect, often greyish or white
sericeo-villose to lanate or tomentose. Leaves narrow, linear to
linear-lanceolate or oblong-lanceolate. Flowers at the end of
distinct peduncles or at the end of the ultimate branches, solitary
or in few-flowered groups. Sepals variable, ovate or elliptic to
lanceolate, obtuse to acuminate, the inner ones often with scarious
margin. Corolla subentire, superficially lobed or deeply lobed,
rotate to widely funnel-shaped.

The species of this section seem to be closely related to each
other. They show resemblance to definite forms of the Alsinoidei-
Pedunculati, but in order to enlarge the unity in the latter group,
it is better to maintain them as representatives of a separate
section. By the erect habit, the often grey or white hairiness,
the form of the sepals and the corolla, they are sufficiently
characterized. Often there is no distinct difference to be seen
between the peduncles and the ultimate flower-bearing branches.
At the end of the latter the flowers are often situated in the
axils of the uppermost small leaves, close together, sessile, shortly
pedicellate of even very shortly pedunculate.

PARAGUAY, near the Upper Apa River, on stony ground, Nov. 1901.
Hassler 7836. type (B, Boiss, K, NH, P).

Perennial (?), lignescent at the base, erect, quite glabrous or
sparsely appressed-pilose. Leaves lanceolate to oblong-lanceolate,
attenuate towards both ends. Flowers solitary at the end of the
ultimate filiform branchlets, in a very broad panicle. Sepals
oblong-lanceolate or lanceolate, acute, the inner ones with
scarious margin. Corolla 5-lobed, rotate to funnel-shaped.

This section is no doubt closely related to the preceding one.
The general habit of the only species shows some resemblance
to the widely branched var. capillaceus of E. elegans. In order
not to break the unity in the Linoidei. I deemed it better to keep
the sections separate. Whilst the hairiness in the Linoidei is in
general strongly developed, it is totally or almost lacking in
E. paniculatus. The leaves of the latter are also different and
the plant is presumably a perennial, whilst the Linoidei are
undershrubs or shrubs.

describe this species as the type of a new genus, Cladostyles,

a genus according to them closely related to Evolvulus but
differing from it in the calyx, the number of styles, the number
of seeds and the indehiscent fruit. As to the first difference, the
calyx is not obviously different from other species of the genus
E., only it is glabrous, and this seldom occurs. The number of the
styles is quite the same as in all other species of the genus.
The number of ovules is four; only one develops, the other being
suppressed, a character not rare in the genus. As to the
indehiscence of the fruits, I was able to examine a number of
them, which showed distinct valves.

Meissn. in Mart. Flora Bras. VII (1869) p. 332, 355; Peter
in Engl.-Prantl, Nat. Pfl. fam. IV, 3a (1897) p. 19.

Undershrubs or shrubs, generally erect; leaves and hairiness
variable. Flowers axillary, solitary or in few-flowered clusters,
spread over the stems or on short lateral branches, sometimes
more or less approximate at the top of the stems but never
aggregate in dense spikehke, terminal inflorescences, generally
pedicellate; peduncle when present extremely short, only in one
species longer. Corolla rotate to widely funnel-shaped, the tube
always very short, the limb subentire or superficially to distinctly
5-lobed.

Of the species which Meissner included in the Passerinoidei
E. speciosus belongs to the Alsinoidei-Epedunculati. The ele-
ments composing the section Ambigui Meissn., viz. E. latifolius,
E. thymiflorus and E. daphnoides seem to be closely related to
definite species of the Passerinoidei, so that I have united these
two sections under the name of the latter.

The only representative of Meissner's Racemulosi viz. E. phyU
lanthoides Moric. must be also reckoned to this section.

Hooker stated as the difference between E. purpuro-coeruleus
and E. arbuscula that the leaves in E, arbuscula are smaller and
erect, not tapering at the base, but a comparison of the type
specimens of the two species and an examination of different
other numbers indicated that both represent the same species.
Hooker termed the colour of the flower of E. purpuro-coeruleus
quot;rich ultramarine blue, with the centre white and a purple ray
diverging from that up the centre of each lobequot;.

The hairiness of the different specimens of E. arbuscula is
rather variable, from densely whitish villose or tomentose to
nearly glabrous. The very densely white villose-tomentose forms
with small scale-like leaves correspond with E. canus Spreng.;
this I consider as a variety of E. arbuscula.

The type of E. pulchellus Meissn., which fully agrees with
E. arbuscula is represented by a specimen in the herbarium
Leningrad bearing the number Blanchet 2570. Under that number

Blanchet also collected specimens of E. elegans Moric. and I
presume that a branch of the non-Brazilian E. arbuscula has been
accidentally included here.

E. canus Spreng, ex Choisy in Mém. Soc. Phys. Genève VIII
(1837) p. 73 in syn.; id. Conv. Rar. (1838) p. 151 in syn.

The young parts densely white or grey villose-tomentose.
Leaves small, more appressed to the branches, those of the short
and stiff ultimate branches often almost scale-like. According to
Ekman the plant has an aromatic scent.

Meissner justly points out the great resemblance with E. jaco-
binus and E. thymiflorus. He is incorrect when he mentions
E. rufus as closely related. This species differs to a great extent
from E. passerinoides and belongs to another section.

No doubt is near E. jacobinus Moric. and very closely resem-
bles it, only differs in the characteristics mentioned above.
Meissner described it as a var. of E. frankenioides, with which
species it has only a very superficial likeness. The hairiness being
less dense than in the typical form of E. frankenioides, Meissner
called this var. glabrescens. but as the hairiness is just much
denser than in E. jacobinus, it is inconsequent to maintain this
name. I therefore propose to change it into var. ramosus.

Two other specimens, a stout and large one, and a more
slender one collected by Sellow, in herb. Berlin, are intermediate
between the species and the variety with regard to the form of
the leaves. These are ovate to broad-ovate, obtuse and mucronu-
late and attain a length of 7—10 mm and a width of 5—8 mm in
the largest of the branches and of respectively 5—6 mm and
4—4.5 mm in the smallest. A specimen in herb. Copenhagen,
collected by Lund agrees with the largest branch.

As the name E. phylicoides was already preoccupied by Schrä-
der before 1841 when Martius used it, it has to be changed. In
accordance with the general habit of the plant which resembles
some species of Genista I chose the name E. genistoides.

The type has the leaves not very revolute at the margins, other
specimens, e.g. Booms, Glaziou 606, 6054, de St.-Hilaire B^ 200
have leaves with a so strongly enrolled margin that they appear
to be linear. In the remaining characteristics they resemble the
type so fully that it is not doubtful whether they belong to this
species. The type of Meissner's var. subsericeus of E. diosmoides
Mart, corresponds very closely with the type of E. genistoides.
Choisy considered the species as a variety of E. diosmoides.
Indeed E. diosmoides and E. genistoides very much resemble
each other, but the differences in hairiness, in leaf-form and
density of the leaves are so great that I keep them apart for
the time being. Moreover transitional forms are unknown.

elliptic or oblong, acute or rounded at the base, obtuse and
mucronulate at the apex, the margins revolute, 10-20 mm long
and 4—8 mm broad, those of the younger branches narrow-

Differs from E. scoparioides Mart, principally by its broader
leaves, which are narrow-elliptic to oblong instead of linear-
oblong or narrow-oblanceolate, by the revolute leaf-margins and
the at the lower surface of the leaves prominent nerves. The
deeply 5-lobed corolla is also different,

E. genistoides v. Ooststr. differs from E. diosmoides by the
dense indumentum and the form and density of the leaves.

spreading, the young parts appressed-pilose with short soft hairs,
the older parts glabrous, brown or blackish. Leaves subsessile or
shortly petioled, linear-lanceolate or linear-oblong, attenuate
towards both ends, obtuse at the apex, acute or obtuse at the
base, densely or sparsely and shortly pilose beneath, sparsely
pilose above, especially on the midrib, or quite glabrous above,
20—35 mm long and 4—9 mm broad; petiole at most 1 mm long.
Midrib prominent beneath, lateral nerves indistinct. Flowers

solitary or in 2—3-flowered groups in the leaf-axils; peduncle
very short or none, pedicels slender, mostly longer than the
sepals 4—6 mm, short-pilose. Sepals equal, ovate or eUiptic.
obtusilh, glabrous or sparsely short-pilose, sparsely ciliate, nearly

tube short, the limb 12 mm in diam.. distinctly 5-lobed; the lobes
broad-ovate, obtuse, with sparsely sericeous band outside. Fila-
ments inserted near the base of the corolla, 13^ times as long
as the linear anthers. Ovary ovoid, glabrous; primary style
branches shorter than the secondary. Capsule ovoid, 6—7 mm
high, 2-valved, 1-seeded. Seed ovoid, black, smooth.

fleshy tube, not much longer than the sepals, which on the top
bears 5 erect, small lobes. The stamens are inserted at the top
of the tube and are provided with very short filaments. The
ovary seems to be normally developed. I suppose that we have
to do with a gall here.

This species has often been confounded with E. cardiophyllus
Schlechtend., a native of Mexico and the north-western part of
South America, with which species there is a great resemblance
in the form of the leaves and in the place of the flowers. The
flower itself however differs to a great extent. The original
description and drawing of E. latifolius were made from a spe-
cimen which flowered quot;in the hothouse at the nursery of Messrs.
Colville, King's Road, Chelseaquot; (Ker-Gawler I.e.). As I do not
know if any dried material of this plant was preserved I choose
as lectotype of this species the specimen Gaudichaud 565, cited
by Choisy in DC. Prodr. I.e.

Meissn. in Mart. Fl. Bras. VII (1869) p. 330, 337, excl.
E. stricto et E. echioide; Peter in Engl.-Prantl, Nat. Pfl. fam. IV,

Perennials or suffrutices, rarely annuals. Stems generally erect,
rarely ascending, terete. Leaves of different shape, linear, lan-
ceolate, oblong, elliptic or ovate; the upper leaves passing into .
the leaf-like bracts of the terminal, generally dense, inflorescences.
Flowers sessile. Corolla salver to funnel-shaped, exceeding the
sepals; tube long or short; filaments inserted at the mouth of
the tube.

Meissner I.e. distinguishes a section Bracteosi and a section
Phyllostachyi. The former he characterizes with the following
words: Flores dense capitati v. spicati, omnes vel saltem inferiores
folio (caulinis simili) fulti; the latter with: Flores in axilla folio-
rum summorum caeteris conformium approximati, spicam dense
foliosam formantes. In the former section he distinguishes
successively plants with inflorescences with leaflike bracts to the
top (E. alopecuroides. Chamaepitys and lithospermoides) and
with inflorescences showing only at the base leaflike bracts and
at the top small lanceolate bracts (E. glomeratus). The first three
species totally correspond, as concerns the inflorescence, with the
Phyllostachyi. to which group I attach them. On the other hand
I consider E. glomeratus as a representative of a separate section,
that of the Involucrati. The name Bracteosi I do not maintain as
it is not so applicable in this case. The species E. strictus Benth.
and E. echioides Moric. which Meissner places with the Phyl-
lostachyi belong to E. glomeratus.

The excrescent inflorescence is sometimes crowned by a tuft
of leaves, as Meissner observes in the manner of a Melaleuca.
Later on flower-bearing leaves develop again so that in this case
it occurs, e.g. in the specimens collected by Sellow, that at the
top of the stem flowers appear, thereunder leaves without flowers
and thereunder leaves with capsules in their axils.

The type-specimen has the leaves distinctly woolly-villose
beneath, they are rather flat and are rather dense. Other spe-
cimens, e.g. Pohl 2941 (Meissner!), in herb. Vienna and Glaziou
21795 very closely resemble it, they are however more strongly
branched and the upper leaves are more dense. Still more dense
are the leaves in Pohl 2941 (without Meissner's handwriting)
and Pohl s. n. both in herb. Vienna. Moreover the leaves are
often folded longitudinally and curved in dried specimens. Next
to the species Meissner distinguished a var. caespitosus, based
on specimens of Pohl in herb. Vienna (Pohl s.n., with Meissner's
identification), Brussels and Munich. In habit these specimens
fully agree with the other plants collected by Pohl under n. 2941.
The hairiness however is less woolly, at any rate in the older
parts, the younger parts have a haircloth which much resembles
that of the typical form. Anyhow the variety of Meissner seems
of little value and had better to be united with the species.

The type of this variety in herb. Munich, collected by Martius,
bears the name E. desertorum Mart, in his own handwriting. The
great resemblance with E. Chamaepitys Mart, led me to consider
it as a variety of this species. The label bears also the name
E. desertorum Mart, in the handwriting of Choisy. Meissner
later on added his identification as E. glomeratus Nees et Mart,
var. desertorum Meissn. Surely this plant does not belong to tike
group of forms of E. glomeratus but is more closely related to
E. Chamaepitys Mart. In his work in De Candolles Prodromus
Choisy mentions under E. desertorum the specimens Gomes and
Luschnath, both belonging to E. glomeratus N. et M. ssp. obtusus
(Meissn.). Helwig's E. longitubulosus fully agrees with the type
of Martius.

Choisy (1837, 1838) gives a description which partly refers
to this species, partly to E. Maximiliani Mart. He confused the
original description of St.-Hilaire with that of a specimen of
E. Maximiliani. which Martius collected near the Rio del Monte.
This specimen bears in Martius' handwriting the name E. imbri-
catus. Choisy thought this specimen to be identical with the
species of St.-Hilaire, the type of which he did not know. This
appears from the fact that Choisy gives the name E. imbricatus
M^t. as synonymous to E. vufns. Meissner (1869) did not know
the type of £. rufus either. He places this species, based on
St -Hilaire's description, next to E. Maximiliani in the section
Passerinoidei. A specimen collected by Warming, which rea ly
belongs to E. mfus. Meissner classifies as E. kramedotdes. Gla-
ziou also places a specimen of E. rufus in the last named species.
Indeed E. mfus is closely related to E. kramenoides but differs
from it by the short sericeo-tomentose strongly appressed, dense
indûment, the non-glabrous upper surface of the leaves, perhaps

also in the larger corolla and in the length of the filaments and
anthers, the latter being in E. kramerioides about 1 mm and in
E. mfus about 3 mm long.

The type of this species was considered by Meissner as
belonging to E. glomeratus Nees et Mart. var. strigosus Choisy.
The inflorescences leafy to the top however greatly differ from
those of E. glomeratus. This species is typical in the appressed
hairiness of the stem and the long patent hairs on the leaves,
especially at the margins. In the inflorescences the hairiness is
sometimes somewhat floccose.

The type of E. aureo-brunneus Helwig closely resembles the
specimens of E. helichrysoides Moric. Helwig mentions a diffe-
rence in the indûment and in the form of the leaves but in the
specimens of the type-number I could compare with Helwig s
plant both are quite the same. The specimen of Martius has the
leaves slightly broader than the type, more ovate and about twice

habitually show a striking resemblance to this species and are
at first sight not or hardly to be distinguished from this The
indûment is completely identical. However, the flowers are diffe-
rent the style is simple with 2 globular stigmas and the corolla
is funnel-shaped. On close comparison the leaves also appear
to have a slightly different shape; whilst the greatest breadth
of the leaves in E. helichrysoides lies in or under the middle, this

lies above the middle in the specimens of Riedel; the leaves are
oblong to narrow-obovate, attenuate to the base, short-apiculate.
Presumably the specimens represent a new species of the genus
Merremia.

An undershrub, densely ferrugineous tomentose throughout,
the stems rather thick, erect or ascending, few or several from
a woody base, simple or ramified in the lower part, 15—35 cm
high. Leaves sessile or with a very short petiole, elliptic, ovate
or oblong, generally obtuse at the apex, sometimes acute; obtuse
or rarely subcordate at the base, 3—5.5 cm long, 1.75—2.5 cm
broad, 1.5—2 times as long as broad, (midrib and 2—4 pairs of
lateral nerves prominent beneath), gradually diminishing in size
towards the base and the apex, the upper ones imbricate and
generally broad-ovate to orbicular, obtuse or acutish, 12—24 mm
long and about as broad, forming a terminal spike, sometimes
accompanied by a few short lateral spikes in the axils of the
upper leaves. Flowers sessile or very shortly pedicelled in the
axils of the imbricate leaves, the lower ones also more remote in
the axils of the other ones. Bracteoles linear, as long as the sepals,
villose (Meissn.). Sepals equal in length, narrow-lanceolate, long
acuminate, scarious, glabrous or almost so at the base, villose

Chiefly due to differences in the shape of the leaves and in
the hairiness we can distinguish the following varieties.

greyish-brown or greyish. Leaves often smaller, elliptic to elliptic-
oblong. obtuse at the apex and at the base, 2.5—3.5 (—4.5) cm

Meissner describes the type of this species as a variety of
E. glomeratus Nees et Mart. However there is a great difference
with the other forms of this species. In E. glomeratus only the
lower bracts of the inflorescence are leafshaped whilst in this
species all bracts are. It is true the upper ones are somewhat
smaller, but the mutual difference is but slight. As regards this
characteristic E. brevifolius corresponds with the Phyllostachyi
and appears to be closely related to E. chapadensis Glaz. As it
has already been observed with E. glomeratus Nees et Mart,
ssp. eU'glomeratus, f. strigosus, the plate of the type of E.
echioides Moric. i) shows a much greater resemblance to E.
brevifolius than to the type-specimen of Moricand.

Meissner i) divided this species into 8 varieties. Of these
I consider the var. E. brevifolius as a distinct species; the var.
^ desertorum belongs to the forms of E. Chamaepitys Mart.
The var. C obtusus represents a distinct ssp. of E. glomeratus.
Of the remaining ones j3 lanceolatus, S excrescens and i
albicans are united with the type of E. strictus Benth. under the
name f. strictus as a form of the ssp. eu-glomeratus of E. glo-
meratus. Of this ssp. I further distinguish the forms genuinus
(var. a genuinus Meissn.) and echioides (E. echioides Moric .
E. glomeratus N. et M. var. strigosus Choisy). The third ssp.
is based on E. grandiflorus Parodi.

with short axillary shoots, consisting of small leaves and some-
times with small, lateral inflorescences, shortly petioled, patent
or erect, the lower ones at distances of 1—1.5 cm, the upper
ones remote, distances up to 5 cm; the blade ovate-oblong,
oblong, oblanceolate or spathulate, attenuate into the petiole,
obtuse or short-apiculate at the apex, appressed-pilose on both
sides, finally glabrescent above, 15—30 mm long, 6—12 mm
broad, 2.5—3.5 times as long as broad, rarely longer; the petiole
2—3 mm long. Midrib and lateral nerves more or less
conspicuous. Inflorescences rather small, dense, brown villose,
terminal and lateral in the upper leaf-axils or at the end of
short, apical, lateral branches, ovoid or globose, sometimes

elongating afterwards. Lower bracts leaflike, obovate or oblan-
ceolate, forming a kind of involucre, the upper ones narrower,
linear, as long as the sepals or shghtly longer, 4.5—6 mm long,
later often longer. Corolla blue, 10—12 mm long, the tube 4—5
mm long, the limb about 12 mm in diam., with 5 pilose bands
outside. Filaments 1.5—2 times as long as the linear-oblong
anthers.

Stems generally erect, woody in the basal part, densely greyish
or brownish appressed-villose to villose-tomentose, glabrescent
below, 20—40 cm high. Leaves sessile or very shortly petioled,
erecto-patent, patent or sometimes deflexed, oblong-lanceolate,
lanceolate or linear-lanceolate, obtuse or acute at the apex,
attenuate at the base, densely appressed-villose to villose-
tomentose on both sides like the stems, 20—30 (—^40) mm long,
2—6 (rarely —10) mm broad, (2.5—) 3.5—4.5 (—10) times
as long as broad, rarely shorter, gradually diminishing in size
towards the apex, the upper leaves mostly less remote than in
the preceding form. Small axillary shoots often developed.
Inflorescences at the end of the stem and the branches, sometimes
aggregated into a terminal panicle, densely flowered, globose
or ovoid, afterwards often elongated and cylindric, often inter-
rupted at the base; lower bracts leaflike, upper ones narrower.

as long as the sepals or exceeding them, often with more or less
incurved apex. Bracteoles lanceolate, 1.5 mm long. Sepals linear-
lanceolate, about 5 mm long. Corolla as in the typical form, blue
or white.

Typical specimens of this form are mostly robust, erect plants
with a dense villose-tomentose to tomentose indûment from brown
to grey colour. Plants with very dense greyish indûment, which
have been described by Meissner as var. albicans, do not or
scarcely differ. Leaves often more or less conduplicate or with
revolute margins.

Perennial, generally 10—20 or occasionally to 40 cm high,
densely brown hairy with spreading hairs. Stems few or several
from a woody base, erect or ascending, densely patent-villose
and appressed-villose to villose-tomentose. Leaves subsessile,
narrow-elliptic, oblong or lanceolate, acute or sometimes obtuse,
the middle-sized ones 10—20 (—25) mm long, 3—5 times as
long as broad, densely hairy like the stems; lower leaves rather
crowded, upper more or less remote. Inflorescences dense,
globose or short-cyhndric, not or shghtly excrescent, the lower
bracts leaflike, the upper ones narrow-oblong to linear. Sepals
4.5—5 mm long or sometimes longer, attaining a length of 8 mm.
Corolla blue, 10—15 mm long, the tube 4—5 mm, the limb about
15 mm in diam. Filaments twice as long as the anthers.

The specimens of E. echioides Moric. [Blanchet 2558, type
(K, Len, NH)] closely resemble the type of E. glomeratus N.
et M. var. strigosus Choisy, they are only more robust, the
leaves and inflorescences being also larger. From a closer com-
parison of the different parts of the flower it appears there is
only a slight difference in the size of the sepals. These are
somewhat larger than in the typical strigosus viz. to 8 mm long.
Such small differences often occur and the very great resemblan-
ces, which undoubtedly exist, induce me to decide to unite the

When the specimens Blanchet 2558 in the various herbaria are
compared with the plate of Moricand, then a peculiar difference
is to be found. On the plate the inflorescence is much longer
and the bracts are not much different from the other leaves,
whilst in the dried specimens a distinct difference exists between
the under and upper leaves in the inflorescences, the
under ones resembling the normal leaves, the upper ones
being much smaller and linear. The plant on the plate shows a
remarkable resemblance to the var. brevifolius Meissn. of E.
glomeratus Nees et Mart. See under E. brevifolius (Meissn.)
V. Ooststr.

Choisy distinguished a var. longepilosus of E. echioides, based
on a single specimen collected by Martius in the state of Minas
Geraes, Brazil, between Contendas and Rio S. Francisco. The
original label of this specimen bears the name E. longepilosus in
the handwriting of Martius (obs. n. 1653). It is not clear if this
specimen really represents an Evolvulus. The bad condition of
the flowers being destroyed by insects does not permit of a
further examination. There are some resemblances to the type
of E. echioides but the inflorescences, as far as present seem to
be distinct. In E. echioides there is a difference between the
lower more leaf-like bracts and the upper narrow-linear ones,
one of the reasons that I placed it under E. glomeratus. In this
specimen however the flower-bearing leaves are not much dif-
ferent from the others, only they are smaller and more densely
placed, as is the case in the species of the Phyllostachyi.

Two other specimens mentioned by Meissner as belonging
here are representatives of another genus having a style with
2 branches each ending in a globular stigma.

A specimen collected by Riedel in Minas Geraes. Brazil, being
the type of the var. minor Meissn. I.e. belongs to Croton
timandroides Müll. Arg. (identification by Dr. J. Lanjouw,
Utrecht). A specimen Lund, mentioned by Meissner under var.
strigosus belongs to E. Martii Meissn. (sect. Phyllostachyi).
A specimen Warming (Lagoa Santa) mentioned by Meissner is
the type of a distinct species E. comosus v. Ooststr. (sect.
Phyllostachyi).

Erect undershrubs, woody in the basal parts; leaves generally
narrow, linear or linear-lanceolate, rarely broader, the lower ones
rather dense, the upper mostly remote, with decurrent base, the
stems consequently winged or with narrow ribs. Flowers in dense
terminal spikes; bracts not leaflike, bracts, bracteoles and sepals
densely villose, corolla hypocrateriform, filaments inserted at
the mouth of the tube.

The erect habit, the decurrent leaf-bases, the remote upper
leaves, except in E. niveus Mart., passing into the bracts of the
dense, spicate, well-defined inflorescence form a very typical
group of characters for this section and distinguish it at once
from the other representatives of the genus. Especially the decur-
rent leaf-base is very remarkable in this genus and even in the
family; in all the species of the section it is very conspicuous,
except in E. lagopus, where only small narrow ribs at both sides
of the leaf-base are present.

This species is well characterized by its glabrous, winged
stems its stiff, glabrous leaves with strongly prominent midrib
and its brown-villose, dense, spicate inflorescences. Martius based
his description on a specimen collected quot;in deserto Minarum ^
The only specimen in herb. Martius (Br.) is a plant collected
by Pohl near S. Isidoro, Goyaz, Brazil. This bears the hand-
writing of Martius and I suppose that this plant has to be
considered as the type. The materials did not allow an exami-
nation of the corolla and the stamens. According to Meissner
the flowers agree with those of E. pterocaulon Moric.

In the herbaria accessible to me this variety was only repre-
sented by Riedel 1386 (Len.). This collection shows the habit of
the species, but the stems and leaves are appressed-pilose. The
stems are to 48 cm high, the leaves have a length of 3—4.5 cm
and a breadth of 5—7 mm; the upper ones are also decurrent.
Corolla funnel-shaped, blue, about 15 mm long, the tube narrow,
about 5 mm long. Filaments inserted at the mouth of the tube.
Ovary ovoid, glabrous.

The hairiness of this species is rather variable. In the type
and in several other specimens (e.g. Ule 7407, Blanchet 246, id.
375) it is densely villose-tomentose with brown or whitish hairs,
other plants show a less dense villosity. Here belong among
others the specimens Lôfgren 1080, Lund, Riedel 2358. The
type-specimen of E. pterygophyllus Mart. var. pubemlas Meissn.
(Riedel 1386) shows a remarkable resemblance to certam
specimens of this species, especially to the less densely hairy ones.
The form and the stiffness of the leaves however is much like
E. pterygophyllus, they show the same attenuate, acute apex as
this species. A further research of specimens from the type- and
neighbouring localities has to decide in how far E. pterygophyllus
var. puberulus and E. pterocaulon are distinct from one another.
The leaves of E. pterocaulon are generally lanceolate or oblong-
lanceolate; occasionally they are broader, ovate- or obovate-
oblong (Ule 7407, Blanchet 375). The first of these specimens
has the bracts and sepals also broader, they are respectively
lanceolate, short-acuminate and narrow-lanceolate, long-acumin-
ate. Blanchet 246 has the stems densely leafy throughout.
Blanchet 375 has the cylindrical inflorescence to 12 cm long.

As regards the hairiness of the stems and leaves 2 forms may
be distinguished, the typical form and the var. floccosus.

Stems and leaves densely floccose or floccose-lanate. Hairs
generally white or greyish-white.

The numbers Swainson and Othmer respectively mentioned

The former is perhaps nearer to the typical, the latter to the
floccose form.

Stems erect or slightly curved, slender, slightly branched,
terete, only with very narrow decurrent ribs at both sides of
the leaf-bases, sparsely appressed-pilose towards the top,
glabrescent and lignescent at the base, green or reddish-brown,
up to 60 cm high (Martius). Leaves sessile, linear, attenuate
towards both ends, acute at the apex; moderate leaves to 40 mm
long and 3 mm broad, diminishing in size towards the top of the
branches, the upper ones narrow-linear, only 10 mm long and
0.5 mm broad, remote; all covered with short, soft, appressed
hairs, glabrescent above; internodes 1—2 cm long, the upper
ones longer, to 4 cm. Midrib generally distinct, lateral nerves
invisible. Inflorescences terminal, solitary or rarely accompanied
by a lateral one, densely spicate, sometimes interrupted at the
base, ovoid or cylindric, 2—6 cm long, long brown villose; lower

bracts narrow linear-lanceolate, upper ones linear, all with long
filiform acumen, exceeding the sepals, long brown villose, bract-
eoles minute, 0.5 mm. Sepals from a linear-lanceolate base long
filiform, long brownish villose, 5 mm long. Corolla salver to
funnel-shaped, bright lilac, up to 15 mm long, the tube shghtly
exceeding the sepals, 6—7 mm long, the limb with 5 pilose bands,
according to Meissner 12—16 mm in diam. Filaments 1.5—2
times as long as the linear anthers. Ovary globose, glabrous.
Capsule not seen.

Shows a resemblance to some specimens of E. pterocaulon, has,
however, a slighter habit, narrower leaves and not the rather
broad-alate stems of the last species. On the contrary only small
ribs occur here on each side of the leaf base. Characteristic are
the long, slender, slightly curved branches with remote leaves.

var. pilosus Choisy in DC. Prodr. IX (1845) p. 441; Meissn.
in Mart. Fl. Bras. VII (1869) p. 334.

Leaves and stems villose with whitish spreading hairs; leaves
smaller than in the species, 10—14 mm long and 1—2 mm broad,
more dense. Internodes short, only 2 mm long in the basal parts,
in the apical parts longer.

BRAZIL, Bahia, Serra de Tiuba, in herbaceous vegetation, fl. March,

Meissner was incorrect when he considered this as a young
specimen of the species, the woody stem, densely covered with
leafscars making this opinion improbable. For the present I wish
to maintain the var. beside the species till further material is
available. No doubt it is closely related to E. lagopus, it shows

the same ribs at both sides of the leafbase, just as in this species,
the ribs are however shorter and the leaves more dense.

Stems simple or slightly branched, erect, with erecto-patent
branches, according to Meissner 30—45 cm, according to Choisy
60—90 cm high (the branches in herb. Munich are 30—40 cm
long), densely leafy throughout, lignescent at the base, alate
by the decurrent leaf bases. Leaves linear-lanceolate, attenuate
to the apex, acuminate, slightly contracted at the base, decurrent
on the stem (the wings 0.5—1 mm broad), greyish-white lanate-
sericeous on both sides, 2—3 cm long, 3—5 mm broad, slightly
diminishing in size towards the top of the stems, the upper leaves
very dense, almost imbricate; midrib distinct, impressed above,
prominent beneath. Inflorescences terminal, solitary or accom-
panied by a smaller lateral one, sometimes also a small sessile
lateral one at half the height of the stem, all more or less globular,
dense, long greyish or brownish villose, 1—2 cm in diam. Bracts
linear-lanceolate, long acuminate, long villose, one-nerved, the
upper ones 6—8 mm long, the lower ones longer and more
leaflike. Sepals equal, with a lanceolate base and a long, slender,
filiform acumen, long greyish-white or brownish villose, 6 mm
long. Corolla etc. not seen.

Very probably the specimen collected by Martius represents
a species of Evolvulus and then belongs to the section Lagopodini,

the habit, decurrent leaves and inflorescences being much like
those of the other representatives of this group. Corolla with
stamens and pistil were absent in the only specimen I saw, and
neither Martius nor Choisy or Meissner gave a description of
these parts.

De Angiospermen kunnen verdeeld worden in vormen met en
zonder echte vruchtbladen.

De naamgeving van phytosociologische eenheden moet vast-
gesteld worden door een door het Internationaal Botanisch
Congres benoemde commissie.

Indien op een Internationaal Botanisch Congres bij de vast-
stelling der nomenclatuurregels niet tot overeenstemming wordt
gekomen, is het noodzakelijk, dat voor de betreffende punten
een voorloopige regeling wordt gemaakt, geldend tot de defini-
tieve vaststelling.

De proeven van C h o 1 o d n y met Avena leveren geen

De verklaring van S i e r p van het verschil in transpiratie in
licht van verschillende golflengte is te verkiezen boven die van

omtrent resistentie van Phaseolus tegenover Pseudomonas medi-
caginis var. phaseolicola Burkh. is onbetrouwbaar voor beoor-
deeling van de resistentie der verschillende boonenrassen
tegenover deze bacterie.

De pseudobranchie der Muraenidae is niet. zooals G r a s s i
beweert, van hyoidalen oorsprong.

De theorie van Brücke-Sabatier over de bloedverdee-
ling in het hart van de Anura is onjuist.

De oogspies van het gewei van de Reuzenherten is niet
homoloog met die van de recente vertegenwoordigers van het
