Aoyama, Mikio (1-59-2 Tomohigashi, Asaminami-ku, Hiroshima, 731-3164 Japan) has published karyomorphological studies of some recently described Paphiopedilum species and also Mexipedium xerophyticum. He is now studying polyploidy in Lycaste and Epidendrum hybrids.
Authier, Pierre (62 rue de Paris, F-93800 Epinay/Seine, France) is currently preparing an orchid flora of Mt. Timfi in Epirus, northwest Greece.
Averyanov, Leonid V. (Herbarium, Komarov Botanical Institute of the Russian Academy of Sciences, prof. Popov str., 2, St.-Petersburg, 197376, Russia) continues his work on the highland flora of south Vietnam and is also studying the limestone flora of Cao Bang province of north Vietnam, both funded by the National Geographic Society. He has recently received a grant from the Russian Foundation for Fundamental Sciences to work on the orchid flora of Russia. He plans trips to Vietnam in October-November 1998 and February-May 1999.
Brasch, James D. (2100 Highview Drive, Burlington, Ontario, Canada LR7 3X4) invites contributions of seeds of rare orchids to the Alexander Parker Orchid Species Propagation Laboratory at the Royal Botanical Gardens, P. O. Box 399, Hamilton, Ontario, Canada. Seeds should be sent to Peter Thomson, Laboratory Supervisor, 525 Vanguard Crescent, Oakville, Ontario, Canada L6L 5G6 or contact email@example.com.
Christenson, Eric (1646 Oak Street, Sarasota, Florida 34236-7536, USA) expects publication of Icones Orchidacearum Peruvianum (with D. E. Bennett) in August 1998. He needs variegated or spotted-leaved species of Sarcoglottis.
Clark, Allen (335 NW 79th Street, Seattle, Washington 98117-4016 USA) requests manuscripts and illustrations (preferably line drawings) treating taxonomy, culture, and hybridization of the tribe Maxillarieae for the quarterly journal Maxillarieae.
Davies, Kevin L. ('Briardale', Church Road, Ystalyfera, Swansea, W. Glam. SA9 2DA UK) has completed a paper on the ultrastructure of the labellar epidermis in Maxillaria for the Botanical Journal of the Linnean Society and will submit a second paper on the same subject soon. He needs fresh flowers of species of Mormolyca, Xylobium, and Scuticaria for low-vacuum SEM studies of the labellum.
Fairhurst, Kathleen Mary (Greenhill Cottage, Cradley, Malvern, Worcs. WR13 5JE, UK) is now sowing seeds of epiphytic orchid species for distribution as deflasked seedlings to the trade and would appreciate donations or exchanges of seeds or protocorms.
Farrell, Lynne (SNH, 1 Kilmory Estate, Kilmory, Lochgilphead, Argyll PA31 8RR, UK) is monitoring a population of Cephalanthera longifolia in Argyll, Scotland.
Gravendeel, B. (Rijksherbarium/Hortus Botanicus Leiden, PO Box 9514, 2300 RA, The Netherlands) is halfway through her PhD on the morphological and molecular phylogenetics of Coelogyne and allied genera (Epidendroideae, subtribe Coelogyninae). A PCR RFLP data set was collected from 8 noncoding regions of the chloroplast genome for 40 species. The chloroplast data suggest that: a) some morphologically recognized sections within Coelogyne are paraphyletic. b) Neogyne, Panisea, and Pholidota are firmly nested within Coelogyne. To add more resolution to the data set, sequences of chloroplast and ITS regions are being collected at the moment.
Harris, Wayne K. (Queensland Herbarium, Mt. Coot-tha Botanic Gardens, Mt. Coot-tha Road, Toowong, Queensland 4066, Australia) is preparing a revision opf Diplocaulobium and would be willing name taxa thereof. Future frield trips include the Mussua Islands (northern limits of Papua New Guinea) in March 1999 and the Torricelli Ranges of Papua New Guinea in June 1999.
Husak, Stepan (Institute of Botany, Hydrobotany Department, Dukelska, CZ- 379 82 Trebon, Czech Republic) is monitoring the recurrence of some marsh orchid species in the Czech Republic). He is able to offer living plants of Dactylorhiza majalis and D. incarnata from seed and willing to name orchid species of wetlands, especially in Central Europe.
Kurzweil, Hubert (Compton Herbarium, National Botanical Institute, 7735 Claremont, South Africa) has completed (with Peter Linder) Orchids of Southern Africa, which should be published in July 1998.
Manilal, K. S. (University of Calicut, Calicut 673 635, Kerala, India) has commenced a book on the orchids of the Western Ghat rain forests of India.
Pedersen, Henrik A. (Botanical Museum, University of Copenhagen, Gothersgade 130, DK-1123 Copenhagen K, Denmark) has recently completed an empirical search for suitable taxonomic concepts to be applied in a biosystematic study of Dactylorhiza, to be published in Nordic Journal of Botany. He is currently conducting a study of allozyme variation in species of Epipactis and will soon commence a long-term biosystematic study of Dactylorhiza. In June 1998 he will travel to northern Greece to study Dactylorhiza. He is willing to name species of Dendrochilum (Philippines) and Pteroceras (whole range) and would like to establish contacts and exchange reprints with others working on Dactylorhiza and other Eurasian orchids.
Tokuhara, Ken (Dogashima Orchid Center, 2848-1 Nishina, Nishiizu-cho, Kamogun, Shizuoka 410-3514, Japan) has recently finished a publication on somaclonal variations in flower and inflorescence axes of plants propagated by culture of flower stalk buds of Phalaenopsis and Doritaenopsis.
