The May meeting will be the 14th and will be presented by Leon Glicenstein Ph.D..

Leon will be speaking on “Jewel Orchids”.

Leon Glicenstein Ph.D. began growing orchids in 1954, and became assistant to the curator of orchids at the Brooklyn Botanic Gardens, then Carl Withner, from 1957 to 1960. He has advanced degrees in Chemistry and Horticulture, with an emphasis on plant breeding, cytology, and cytogenetics. Working as a plant breeder for five years at Linda Vista S.A. in Costa Rica, he photographed, in the wild, approximately 80% of the then known orchid species of Costa Rica. He also found new species such as Telipogon glicensteinii, Macroclinium glicensteinii, Pterichis leo, Stenorrhynchos glicensteinii, and Lepanthes glicensteinii. He won the second American Orchid Society Dillon/Peterson Essay Contest using one of his Costa Rican experiences. He has photographed many of the orchids in the Northeastern United States, Florida, and all of the orchids in California, where he located some taxa not formerly known to exist there. As a respected lecturer, has given numerous conservation oriented programs both nationally and internationally, showing orchids growing in their native habitats. Leon has been an invited guest speaker at both the Vancouver and Miami World Orchid Conferences. He has published numerous articles in the American Orchid Society magazine [including a 10 part series on Jewel and Painted-leaf Orchids with a supplement] and some in the Orchid Digest.

Leon joined Hoosier Orchid Company in September 1998. As a breeder, as well as a grower, of orchids at Hoosier Orchid Company Leon specialized in working with members of the Pleruothalidae, Zygopetalinae, Gongorinae, Angraecoid, Jewel and Painted-leaf orchids, as well as other groups. He has created numerous novel and new combination not before known, thereby extended our knowledge of generic relationships within the orchid family. Since the demise of Hoosier Orchid Company Leon has been consulting with other orchid companies on growing orchids from seed.

A strong conservationist, Leon was a past chairperson of the American Orchid Societies Conservation Committee, and had been a member of this committee for decades. He represented the AOS at the international conservation meeting in Costa Rica in 2007. In 2013 Leon was elected to the position of “Fellow of the American Orchid Society” for “… outstanding contributions to conservation, hybridizing, and the educational advancement of the Orchidaceae” [AOS’s words], an honor given to only nine other people since the inception of the American Orchid Society.

Before coming to Hoosier Orchid Company he worked for an internationally known plant breeding company breeding crops such as Chrysanthemum, Carnation, Azalea and Roses.
