Botany (CAS-BOT-BC)

The slopes of Colombia, China's Yunnan Province, the plateau forests of Madagascar, the fields of California - Academy botanists travel the world to discover new species, collect plants for our herbarium, and contribute to our extensive database. With a history of pioneering action that began in 1893 with botany curator Alice Eastwood, today's department is a robust collection of leading researchers, scientists, fellows, and students. Our resources include a 2 million specimen collection containing more than 11,000 types, as well as the John T. Howell Botanical Laboratory.
