Introduction

With the presentation of our Index Seminum 1991 we take the opportunity, as usual, to inform you on the latest developments concerning the Botanic Gardens of Utrecht University.

In the past year, for the time being, the last phase of the building-project of our greenhouse-complex at the University center quot;De Uithofquot; has been completed.

The greenhouse-complex, with a total area of more than 5000 m’ , now includes 32 seperate departments, three of which are cooled. The complex also includes a department with climate-chambers and cold storage containers. There also is a special department for the public, with possibilities for exhibitions, lectures and catering.

At this time the construction of tunnel-greenhouses with foil cover at Fort Hoofddijk has started. This will be used to protect a large part of the outdoor experiments against extreme weather conditions.

The seedbank facilities are expanded so that the quality of the material can be better safeguarded.

We expect that in the next few years the development of the Educational Department will be a central issue. The services for the general public and for education will be expanded.

The Educational Department, introduced in 1989, has continued its activities. Mrs. Kühn left our staff, her place is now taken by Mrs. Hanneke Potters.

The gardens attract more visitors each year. In 1992 we estimate a total of 75.000 visitors. The most important special activities in 1991 were:

• - nbsp;nbsp;nbsp;The Sculpture Trail. Fort Hoofddijk was the location for an exhibition of 16 sculptures, specially made for this occasion. The exhibition attracted many visitors and we received very positive reactions.

• - nbsp;nbsp;nbsp;Guided evening-tours. In 1990 we introduced the evening-tours. These are guide walks with a special theme. In 1991 the theme was quot;Plantlorequot;, all kinds of folkstories about plants and the scientific facts underlying these stories.

The congress on education in Botanic Gardens was a success. 76 participants from 20 countries attended the congress and exchanged ideas and opinions. The basis has been laid for an international network. The next meeting of this quot;Botanic Gardens Education Networkquot; is planned in 1993 (Las Palmas).

The Utrecht Botanic Gardens are developing specializations on the following groups and taxa:

-Alpinous plants

-selected woodland plants (Arisaema, Arisarum, Penstemon amp;nbsp;Trillium)

-Annonaceae

-Conifers (esp. Tsuga)

• -Flora of the Neotropics: Flora of the Guianas

Gesneriaceae

Orchidaceae

Zingiberaceae

-Lactiferous plants: nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;Euphorbia

Hoya

-Broad-leaved hardy trees and shrubs:

Aceraceae nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;Betutaceae nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;Ericaceae

Euonymus nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;Laburnum nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;Magnolia

Oleaceae

These specializations are given extra attention regarding verification, nomenclature etc.

We are especially interested in material from natural sources of the groups and taxa mentioned above. In order to start co-operation with gardens with identical specialisations we have included a questionnaire in our previous seedlist (no. 32 -1990-).

Results of our inquiry, held last year (Index no.32-1991): We can inform you, that ca. 10 per cent of the questionnaires were completed and returned.

• 39 Gardens (Institutes) out of those are interested in co-operation, either with us or with our other Dutch colleagues.

19 Gardens (Institutes) did not specialize in certain taxa and/or are not interested in co-operation.

We are quite pleased with this score and and apart from our other contacts it gives us an overall picture of certain specializations. We have the intention to send a newsletter regularly to those who are interested in a further co-operation.

If you have missed the chance to join us in this co-operation project on certain specializations, please contact our Curators Department and we’ll send you the information you need.

Verification:

The seeds in this list have been taken from verified plants and only if we were reasonably sure that cross-pollination with related species would be unlikely. The exception to this rule is seedlist no. 52: Engelhardia spicata. These seeds were collected under conditions not allowing acurate verification.

Explanation of provenance codes:

E= Seeds from natural source

S= Seeds derived from a plant in cultivation but from known natural source ( not necessarily Fl generation).

G= Seeds from a plant from other Botanical Garden or Institute; not from known natural source.
