Carlsward, Barbara (formerly B. Dixon; 4552 Auhuy Drive, Santa Barbara, CA 93110, USA) has recently completed her master's thesis, "Comparative leaf anatomy and systematics in Dendrobium sections Aporum and Rhizobium." She is currently conducting an anatomical study of Hypoxidaceae, often suggested as a close relative of Orchidaceae.

Campbell, Fred J. (Stenbacksvagen 32, S-291 70 Kristianstad, Sweden) is now compiling an extensive report for the World Wildlife Fund on population status and other conservation aspects of Cypripedium calceolus in Sweden. He appeals for other researchers with an interest in this species to answer the questionnaire elsewhere in this issue of the Orchid Research Newsletter. He also reports that in the face of deforestation and the cessation of grazing and manual scything of meadows, some orchid species are now seriously endangered in Sweden, particularly Cypripedium calceolus, Epipogium aphyllum, and Cephalanthera rubra. Funding from local and national agencies as well as the WWF has sponsored conservation projects for Nigritella nigra in Jamtland and for Orchis spitzelii on the island of Gotland. Despite the fact that all orchids have been protected by law there for four years, several sites in southern Sweden have been plundered by European collectors, chiefly for Orchis militaris.

Davies, Kevin L. ('Briardale', Church Road, Ystalyfera, Swansea, W. Glamorgan SA9 2DA, UK) has recently published a series of articles on Maxillaria in the Orchid Review as well as one on the orchid collection of J. J. Neale (1854-1919). He hopes to examine pseudopollen in Maxillaria with SEM soon. He is willing to share material from his collection of 300 species with bona fide students and to collaborate or supervise students working on orchids.

Fernandez, Ricardo (Museo de Historia Natural, Apdo. 140434, Lima 14, Peru) would like locality information concerning Peruvian species of Xylobium as well as flowers in spirit. He also needs the original description of Xylobium zarumense Dodson with photocopies of the type specimen and Peruvian voucher.

Gravendeel, Barbara (Ryksherbarium/Hortus Botanicus, van Steenisgebouw, Einsteinweg 2, P. O. Box 9514, 2300 RA Leiden, The Netherlands) has begun a Ph.D. project on Coelogyne sect. Speciosae and allied sections, incorporating both morphological and molecular data. She would welcome leaf material of all Coelogyne species dried in silica gel.

Kull, Tiiu (Institute of Zoology and Botany, R11A 181, Tartu EE 2400, Estonia) is now monitoring populations of several orchid species in Estonia and would appreciate reprints of papers on population dynamics of orchids in any language.

Marques, Maria Isabel B. (Department of Animal and Plant Sciences, University of Sheffield, Sheffield SL0 2TN, UK) is investigating the impact of arbuscular mycorrhizal fungi on ruderal plants for her Ph.D. work and is interested in orchid mycorrhizas.

Mitra, Madhumi (Department of Biology, University of Puerto Rico, Box 23360, San Juan, PR 00931-3360) has completed a study of intraspecific morphological variation of Spiranthes torta from the Greater Antilles. He is now working on the pollination, reproductive biology, and population genetics of Polystachya concreta and also seed dispersal mechanisms and functional shifts in nectar production in Spiranthes torta.

Nelson, E. Charles (Tippitiwitchet Cottage, Hall Road, Outwell, Wisbech PE14 8PE, Cambridgeshire, UK) is presently preparing a book titled Orchids of Glasnevin with Brendan Sayers, a history of orchid cultivation at Glasnevin, with chapters on Irish native orchids and botanical art. He is also writing an account of Charlotte Wheeler Cuffe's travels in Burma, illustrated by her superb watercolours of Burmese orchids. He has acquired the remaining stocks of several of his botanical books, including John Lyons and His Orchid Manual (1983), and would be pleased to supply individual readers of the ORN with copies at a discount of 50%, i.e. 10.00 or the current equivalent in other currencies. Copies will signed, numbered, and posted overseas by surface mail. Orders may be placed by writing to the address above.

Podevijn, Dirk (Halvemaanstraat 124, 9040 Sint-Amandsberg, Belgium) has recently published a book titled Charles Vuylsteke, fine-fleur van de Belgische sierfeelt, which deals with the origin of Vuylstekeara. The book (in Dutch) may be obtained from Ratcliffe Orchids, Ltd., Owlsbury, Winchester SO21 1LR, UK.

Prendergast, Grace (Sainsbury Orchid Conservation Project, Royal Botanic Gardens, Kew, Richmond, Surrey TW9 3AB, UK) has grown several thousand plants of Cypripedium calceolus from seed for reintroduction in Britain and also some from seed from the French Alps for return to France. She is planning to reintroduce about 100 plants of Orchis simia, which occurs at only three sites in Britain and is part of English Nature's Species Recovery Program.

Reed, Bryan (4 St. Andres Drive, Tividale, Warley, West Midlands B69 1PR, UK) is working toward a Ph.D. on nutritional requirements of Pleione formosana. He would like to hear from anyone studying nutrition of orchids.

Sarosiek, Jan (Department of Ecology and Nature Protection, Botanical Institute, Wroclaw University, Kanonia 6/8, 50-328 Wroclaw, Poland) has completed a chemical and radioecological study of orchids in Poland and is now working on allelopathic activity of orchids in coenopopulations.

Senghas, Karlheinz (Botanischer Garten der Universitat, Im Neuenheimer Feld 340, D-69120 Heidelberg, Germany) has now completed Volume 1B of R. Schlechter's Die Orchideen, 3rd ed. He is now working on the review of the final subtribes Oncidiinae and Stanhopeinae for the new edition and is trying to locate plants, flowers, and seeds of Antillanorchis as well as seeds of Saundersia and Papperitzia for SEM studies.

Schettler, Roland (Erlgartenstr. 73, 44869 Bochum, Germany) continues to edit Journal fur den Orchideenfreund and cultivate seldom-seen dendrobiums from Papua New Guinea. He last visited Borneo in 1995.

Schuiteman, Andre (Ryksherbarium, P. O. Box 9514, 2300 RA Leiden, The Netherlands) has now completed revisions of Mediocalcar and Agrostophyllum sect. Appendiculopsis and also a preliminary checklist of the orchids of New Guinea. He is now preparing a revision of Cadetia, a book on the highland orchids of New Guinea, and (with E. F. de Vogel) a CD-Rom version of orchids of Malesia.

van der Cingel, Nelis A. (Hooiweg 185, 9765 EG Paterswolde, The Netherlands) is preparing a second volume of his Atlas of Orchid Pollination, this one devoted to non-European orchids. He is interested in receiving slides/photographs of orchid pollination from all areas of the world except Europe.

Walter, Kerry S. (Royal Botanic Garden, Inverleith Row, Edinburgh EH3 5LR Scotland, UK) has now completed Catalogue of Plants Growing at the Royal Botanic Garden, Edinburgh, which is also available on the World Wide Web (www.rbge.org.uk) as a searchable database. The database contains country-level and collector and collector numbers for RBGE's ca 40,000 living accessions, including 2,461 living orchid accessions representing 1,395 taxa.
