He is also assisting in the establishment of an orchid herbarium, lath house, and greenhouse to allow the illustration and cultivation of species from northern Peru. He will soon make a field trip to northern Peru with botanists from the University of Antenor Orrego at Trujillo.

Dalstrom, Stig (Marie Selby Botanical Gardens, 811 S. Palm Avenue, Sarasota, Florida 34236-7726 USA) has descriptions of three new species of Odontoglossum and a revision of Solenidiopsis in press. He has completed a treatment of Odontoglossum for the Catalogue of Vascular Plants of Ecuador and is preparing an illustrated treatment of the same genus for Flora of Ecuador. He recently spoke on the genus Odontoglossum at the 16th World Orchid Conference.

Davies, Kevin L. (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 SA9 2DA, UK) has completed his survey of foliar anatomy in Maxillaria. He is continuing his low-vacuum SEM studies of Maxillaria labella and also his TEM and ontogenetic studies of pseudopollen in Maxillaria. He would welcome any surplus plants of Maxillaria and Ornithidium.

Goldman, Doug (Department of Botany, University of Texas, Austin, Texas 78713-7640 USA) is finishing his Ph.D. on the systematics of Calopogon and the Arethuseae. He used sequences of the chloroplast genes matK and rbcL to evaluate tribe Arethuseae and also nuclear ITS sequences, chloroplast RFLP data, AFLPs, chromosome numbers, in situ hybridization, and morphology to evaluate Calopogon, placing special emphasis on C. oklahomensis, which is polyploid and of hybrid origin. He donated most of his living Calopogon collection to Kew, New York Botanical Garden, Missouri Botanical Garden, Atlanta Botanic Garden, and Bok Tower Gardens, while many other plants were returned to the wild.

He needs seed of Cypripedium species and can offer seed of Mediterranean orchids.

(Department of Ornamentals, Research Centre Aarslev, Kirstinebjergvej 10, DK-5792 Aarslev, Denmark) is preparing studies of: 1) phenology of root growth and mycorrhiza in a set of North American terrestrial orchids with different life forms; 2) endophytes, in collaboration with Bruce Caldwell, Tim Daniells, and Dennis Whigham; 3) seedlings of Apostasia wallichii, in collaboration with Finn N. Rasmussen and Bo Johansen; and 4) ultrastructure of infected orchid seedlings, with Bo Johansen.

Ravelomanana, Didier (Departement de Biologie et Ecologie Vegetales, Faculte des Sciences, B.P. 906, 101 Antananarivo, Madagascar) is working on in vitro propagation of orchids as a way of conserving the biodiversity of Madagascar.

Rawat, Gopal S. (Wildlife Institute of India, P. B. 18, Chandrabani, Dehra Dun, India) is currently investigating the conservation status of high-elevation forests in Bhagirathi Valley, Garhwal Himalaya, and would like to carry out status surveys of threatened orchids and other plants in "hot spots" of biodiversity of India.

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.

Vij, Suraj Parkash(Department of Botany, Panjab University, Chandigarh - 160 014, India) has recently completed a study of distribution frequency and habitat preferences of terrestrial orchids. He is currently focusing on 1) the conservation and commercialization of Himalayan plant genetic diversity through biotechnological means, 2) an in vitro study of regeneration-related morphogenetic changes in orchids, and 3) in vitro chromosomal dynamism in orchids. For the future he plans to prepare an enumeration and evaluation of North-west Himalayan orchids, with a trip to the Shimla and Dharamasala Hills there. He has just returned from the Kumaon Hills of Central Himalayas.
