Index Seminum No, 45 - 2003

In response to the Convention on Biological Diversity (CBD), the Utrecht University Botanic Gardens supplies seeds and other plant material in accordance with the Code of Conduct for Botanic Gardens and similar collections. We are IPEN-member (International Plant Exchange Network) and can exchange material with other IPEN-members without bi-lateral agreements

The current IPEN-members are Listed at httr)://www.biologie.uni-ulm.de/verband/cbd/list.html.

Non IPEN-members have to return the “Agreement on the supply of living plant material for non-commercial purposes leaving the International Plant Exchange Network (IPEN version 26)“ which must be signed by authorized staff. This agreement can be made valid for 1, 3 or 5 years and is printed on the back-side of the order form.

Notes on ordering:

• • nbsp;nbsp;nbsp;Correspondents are asked to use the order-form provided, which must be signed by authorised staff, and send it to the address mentioned upon it. Furthermore, they should check with their own authorities concerning import-regulations and include any necessary permits with their order.

• • nbsp;nbsp;nbsp;Only requests, with a maximum of 25 packets, reaching us before March I, 2004 will be handled in sequence of entry.

• • nbsp;nbsp;nbsp;Order-forms which will reach us after that date will not be handled!

• • nbsp;nbsp;nbsp;Our Fax no. is 31 30 2535177 (do not use e-mail).

Specializations:

In the framework of the National Plant Collection (NP), Utrecht University Botanic Gardens are maintaining specializations on the following groups and taxa:

• - nbsp;nbsp;nbsp;Flora of the Neotropics: [EG] Flora of the Guianas, with special emphasis on: Bromeliaceae Orchidaceae Costaceae

  - Broad-leaved hardy trees and shrubs: [HP]

  Aceraceae Betulaceae nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;Ericaceae

  Euonymus nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;Laburnum nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;Magnolia Oleaceae (esp.: Fraxinus and Syringa)

• - nbsp;nbsp;nbsp;Annonaceae (Research Collection) ]EG]

• - nbsp;nbsp;nbsp;Conifers (esp. Tsuga) ]hp]

• - nbsp;nbsp;nbsp;Alpines [EG]

• - nbsp;nbsp;nbsp;Crassulaceae (Research Collection) [EG]

• - nbsp;nbsp;nbsp;selected woodland plants (Arisaema, Asarum amp;nbsp;Trillium') [EG]

• - nbsp;nbsp;nbsp;Penstemon ]EG]

• - nbsp;nbsp;nbsp;Lecanopteris ]EG]

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

We are especially interested in material from natural sources of the groups and taxa mentioned above. We seek cooperation with gardens with identical specializations. If you are interested, please contact us and we will provide additional information.

Aceraceae:

The research within the Aceraceae Project will take place in a number of phases and we wish to thank the following organisations for their cooperation:

Dutch Botanic Gardens Foundation The Maple Society lUCN-SCC Temperate Broadleaved Trees Specialist Group Botanic Gardens Conservation International (BGCI)

One of the goals will be the production of a survey of taxa of Aceraceae, currently considered threatened (IUCN Conservation Categories) present in the Western Botanic Gardens.

This list will be analised and completed with the threatened species native to Temperate Asia. Special emphasis will be put on specimens of recorded wild origin, In this respect we kindly request the help and support of our ChineGóbse colleagues.

BromeUaceae:

Study and devellopment in the BromeUaceae collection has several focus points. In the first place the BromeUaceae research project for the “Flora of the Guianas”: we try to grow all possible species from this area.

Beside this, the TiUandsioideae collection (as Subfamily of the BromeUaceae) is part of the National Plant Collection (NP). The genus Tillandsia of the Andian countries (especially Bolivia amp;nbsp;Equador) has a special attention because of the various taxonomic problems on species level in these areas. To increase the general knowledge about the recognised genera in the Family we try to grow representatives from all genera. It is evident that our Bromeliaceae Collections will increase dramatically in both size and quality.

Arisaema:

The last few years we have been very active with this group, increasing the number of wild collected species in the collection. Some areas, like the Peat Garden, have been improved to grow more Arisaemas. International contact with various Arisaema (Araceae) specialists caused considerable improvement of the collection.

Last but not least, the living collections have been enriched this year. Many new accessions from natural sources replaced accessions from cultivated origin, as part of the long-term collection strategy to replace plants of cultivated origin for wild-collected stock.

Codes used

Explanation of provenance codes of the plants:

W= Accession of wild source

Z= from a wild source plant in cultivation.

G= Garden origin.

All seeds are harvested in the garden or in the arboretum.

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.

Verification codes used:

• 1= determined by comparison with other named plants;

• 2= determined by a taxonomist or other competent person;

• 3= determined by a specialist (taxonomist working on that group)

IPEN-Number:

The first two positions are the iso-code of the country of origin. XX means: country of origin unknown.

The next position is a digit meaning: special restrictions (1) or not (0).

The next position is the abbrevation of our garden (U).

The rest consists of the internal accession number:

The first four digits of it indicate the year of registration, (1900 = unknown year of entry).

The next two characters are coding for the garden location or specific group of plants: GR=Green houses; BL=Rock Garden; ZG=0rig. Von Gimbom Arboretum; RD=Woody Plants; SL= Seedlist only; ZE=Annuals and Biennials; ZS and ZB= Perennials.

The other five digits are a sequence number within a year.

The IPEN-number as a whole stays attached to the accession, wherever it may go, so that it it allways possible to trace back its origin.
