I attended the Eastern Cactus and Succulent Conference in Pittsburgh where Juan Chahinian was one of the noted speakers. Not only was this man information but he gave one of the best lectures at the conference. His knowledge of Sanseverias is by far the broadest I ever heard. His slide presentation was wonderful and included shots of Sansevierias in habitat growing in East Africa during his trips there. I never realized that there were that many species of this genus. I urge everyone that if they get a chance to hear Mr. Chahinian speak to do so immediately. Elias Sassoon Long Island, NY
