Messenger - Vol. 4, No. 1, Page 23 1994 Botanical beauties David Jarrell, Delaware '88, knows his orchids inside out. A doctoral candidate in botany at the University of California at Riverside, Jarrell studies the molecular systematics of a "tribe" of orchids known as Vandeae. Some of the better-known tribe members are Phalaenopsis (or "moth" orchids) and Vanda, both tropical epiphytes that use trees for support. Jarrell also received the 1993 member of the year award from the San Bernardino County Orchid Society.
