Averyanov, Leonid V. (Herbarium, Komarov Botanical Institute of the Russian Academy of Sciences, prof. Popov str., 2, St.-Petersburg, 197376, Russia) has now completed work on the limestone flora of Cao Bang province of north Vietnam and also exploration of endangered calcium-dependent orchid flora in inaccessible rocky limestone areas of north Vietnam. Many projects are in progress or planned for the future: exploration of endangered Vietnamese paphiopedilums (1999-2000), the highland flora of south Vietnam (February 2000-December 2001), and (with Nguyen Tien Hiep) the distribution of Paphiopedilum vietnamense and its current status in the wild (2000-2001).Bajracharya, Devendra (Department of Botany, Amrit Campus, Tribhuran University, Lainchour, Kathmandu, Nepal) has just finished an inventory of the orchid flora of Gorkha District, Nepal, Himalaya, and is now working on a revision of Eria of the Himalaya region.
Bennett, David E. (Francisco Tudela Varela 229, Miraflores, Lima 18, Peru) plans to accompany a photo and video team to the site of Sobralia altissima (by helicopter) to collect pollinia for distribution to Sobralia hybridizers. He is preparing 200 additional Icones with Eric Christenson for publication this year.
Kurzweil, Hubert (Compton Herbarium, National Botanical Institute, 7735 Claremont, South Africa) is to participate in a SABONET expedition to the Nyika Plateau in Malawi in March-April 2000.
