The Genus Sansevieria I: Systematics and Some New Species

Program: Considerable controversy surrounds the genus Sansevieria, which some believe should be subsumed into the genus Dracaena. Preliminary molecular work suggests that the two genera are separate, and character data reinforces this conclusion. At present, more than 100 taxa are in the genus Sansevieria and more are added with each passing year. This talk discusses the systematic of the genus and presents some newly described species as well as some potential species yet to be described in the coming years.

Dr. Robert H. Webb has worked on long-term changes in natural ecosystems of the southwestern United States and Baja California since 1976. He has degrees in engineering (B.S., University of Redlands, 1978), environmental earth sciences (M.S., Stanford University, 1980), and geosciences (Ph.D, University of Arizona, 1985). Since 1985, he has been a research hydrologist with the U.S. Geological Survey in Tucson and an adjunct faculty member of the School of Natural Resources and the Department of Hydrology and Water Resources at the University of Arizona. In addition to his research on long-term change in desert regions, he has collected succulent plants and cacti for 40 years. Webb has authored or edited 14 books and about 225 scientific publications.

He and his wife are the owners of Arid Lands Greenhouses in Tucson, Arizona, and Webb is the former chairman of the International Sansevieria Society. He has described and named ten species or subspecies of plants, including two Agave species from Baja California, Mexico, and eight Sansevieria species or subspecies from East Africa.

Edit: Arid Lands Greenhouses sells many Sansevierias. They mail-order.
