From the Curator’s Department

With the presentation of this Index Seminum No. 38-1996 we take the opportunity, as usual, to inform you on the latest developments in Utrecht University Botanic Gardens.

Concerning our specializations, there has been a special attention to the Aceraceae and Bromeliaceae.

Aceraceae:

This year our Botanic Gardens was asked to be the Host Garden for the I.D.S. Bursary 1996. This Bursary was generously donated by the International Dendrology Society to Piotr Banaszczak, a third-year student of the Agricultural University of Warsaw, Poland. With this Bursary our Acer Project was given a start with the production of a survey of Aceraceae belonging to the Dutch National Plant Collection and a study of these living plants and herbarium vouchers.

The research within this 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)

The next step will be the production of a survey of taxa, cunently 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 should be on specimens of recorded wild origin. We’re especialy asking our Chinese colleagues for their help and support.

Bromeliaceae:

The Tillandsioideae as Subfamily of the Bromeliaceae is since this year part of the National Plant Collection.

Because one of us (Curator Eric J. Gouda) is amongst others developing a veiy keen specialization on Bromeliaceae, it is self-evident that our collections will grow with very valuable accessions.

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 of replacing plants of cultivated origin for wild-collected stock.

-Flora of the Neotropics: Flora of the Guianas, with special emphasis on:

-Annonaceae (Research Collection)

-Conifers (esp. Tsuga)

-Broad-leaved hardy trees and shrubs:

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

-Lecanopteris

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 have a cooperation with gardens with identical specializations. If you are interested, please contact us and we will provide additional information.
