Atwood, John T. (P. O. Box 566, Woodstock, Vermont 05091, USA) has signed a contract with Missouri Botanical Garden as Curator of Orchids in addition to his position of Senior Scientist at the Marie Selby Botanical Gardens. He is now also a Research Associate at the Oakes Ames Orchid Herbarium (AMES) at Harvard University Herbaria.

Averyanov, Leonid V. (Herbarium, Komarov Botanical Institute of the Russian Academy of Sciences, prof. Popov str., 2, St.-Petersburg, 197376, Russia) has recently completed work on two grants, "The distribution of Paphiopedilum vietnamense and its current status in the wild" (Flora and Fauna International) and Highland flora of southern Vietnam" (National Geographic Society). He is now working on several projects: 1) National Geographic Society grants # 6733-00 "Botanical Inventory of Unexplored Areas in Viet Nam: The North"; 2) National Science Foundation grant # DEB-9870231 "Collaborative Research: A Multi-Taxa Inventory of Threatened Conservation areas in Viet Nam"; 3) American Orchid Society exploration programme "Population studies of endemic Paphiopedilum species in northern Vietnam"; 4) San Diego County Orchid Society Conservation Committee exploration program "Field studies of new endemic Paphiopedilums recently imported from Vietnam"; 5)WWF TRAFFIC Southeast Asia - Vietnam exploration program "Discovery of wild populations of Paphiopedilum tranlienianum (Orchidaceae) and its current status in the wild"; and 6) Publication of a poster titled "|Endangered Vietnamese Paphiopedilums" (Flora and Fauna International).

Griesbach, Robert J. (Floral and Nursery Plants Research U.S. National Arboretum, USDA, ARS, BARC-W, BLDG. 010-A, Beltsville, Maryland 20705-2350, USA) reports that research is continuing on the biochemistry and genetics of flower color. He and his colleagues have determined that the color of the blue-flowered forms of Doritis pulcherrima and Cattleya loddigesii is not the result of a change in flavonoid pigments. The flowers appear blue because of an increase in the pH of the vacuole. Studies to determine the genetic regulation of floral pH are currently in progress.

Higgins, Wesley E. (Marie Selby Botanical Gardens, 811 South Palm Avenue, Sarasota, Florida 34236-7726, USA) has been named Director of Systematics at Marie Selby Botanical Gardens, filling the Jessie B. Cox Chair of Tropical Botany.

Li, Heng and Li, Rong (Department of Plant Taxonomy and Phytogeography, Kunming Institute of Botany, The Chinese Academy of Sciences, Kunming 650204, Yunnan, P.R. China) have been compiling Orchidaceae for the Flora of Yunnan and plan trips to the Gaoligongsham Mountains in northwestern Yunnan in July and northern Myanmar in August.

Light, Marilyn (new address: Professional Training Service, University of Ottawa, 139 Louis Pasteur St., Ottawa Ontario, Canada K1N 6N5) continues long-term studies of Epipactis helleborine (this will be the 17th year) and of Cypripedium parviflorum var. pubescens. The unusually extended spring of 2000 in Ontario offered an unique opportunity to examine and discriminate between variables affecting flower opening and fading in these species.

Oakeley, Henry (77 Copers Cope Road, Beckenham, Kent BR3 1NR, UK) acted as caretaker editor of The Orchid Review for the first six months of 2001. His article on adaptations of lycastes to ensure survival, pollination, and seed production was published in the last issue of the The Orchid Review. He is now completing a monograph of Lycaste with descriptions of the recently discovered new species and and of many of the botanical varieties seen in cultivation that have not been described.
