Introduction

With the presentation of this Index Seminum No. 37-1995 we take the opportunity, as usual, to inform you on the latest developments concerning the Botanic Gardens of Utrecht University.

Last year we have had the official start of the Dutch Regional Office BGCI, established and located at our Gardens. This conservation-unit has two major activities. First the development of a Dutch section of the International Plant Charter Group (a business support group) and the development of concrete conservation projects. In January 1995 a major step was set by signing the deed of purchase for the first project, namely the Trésor Project. This concerns the purchase of 2.400 ha of rainforest and wet savanna in French Guiana. This future nature reserve is located about 40 km. south of the capital Cayenne. For more information we invite you to read an article on this project in the B.G.C.-News, Vol.2 (5) August 1995.

In February we started a discussion list concerning Rock Garden and Alpine Plants at Surfhet (Internet). This is done in cooperation with Harry Dewey from Beltsville USA.

For more information contact: E.J.Gouda@cc.ruu.nl

In April we have had the pleasure to organize a congress and an international exhibition with the N.R. W., The Dutch Rock Garden Society. This event was held at the occasion of the 10th anniversary of the N.R.W. One hundred and fifty (150) participants of 16 countries attended this congress.

1995 was also an important year for our students and the general public. After the opening on 22 June of the Theme Garden, Utrecht Botanic Gardens were enriched with 8.000 m2 new garden. This garden was especially designed for all kinds of public. Not only for students but for public of all ages and abilities, including disabled visitors, (see Roots 8, October 1993).

Last but not least, the living collections have been enriched this year. New plant species and accessions for the Theme Garden have been added to the general collections.

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.

S= Seeds derived from a plant in cultivation but from known natural source ( not necessarily F1 generation).

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

K= Nursery origin; not from known natural source.
