Trinidad has long been a center for botanical study, both in regards to its own botanical treasures and as a base for botanists on collecting expeditions to South America and other Caribbean Islands. The Trinidad & Tobago Orchid Society carries on this tradition with projects like the Database of Native Orchid Species. The Database "was completed in 2003 with a listing of over 100 orchid species." Separate orchid profiles include a recently taken photograph, and many also provide a brief description that addresses color, size, flowering period, and habitat. Site visitors can locate orchid species by browsing the alphabetized index or by using the keyword search engine.
