Distribution and habitat edit
T. variegata is native to the Cayman Islands (Grand Cayman), Cuba, the Dominican Republic, Haiti, Puerto Rico, the British Virgin Islands, and the United States Virgin Islands.[1] It inhabits both moist and dry forests at all but the highest elevations, and is the most widespread member of the genus Tolumnia.[3]
Description edit
T. variegata is a stoloniferous plant with flattened pseudobulbs. Plants are variable in size. The leaves are long with a pointed tip, measuring approximately 12 cm (4.7 in) long and 1.5 cm (0.59 in) wide. The inflorescence grows to 40 cm (16 in) long, bearing up to 30 flowers.[4] The flowers are highly variable in size, shape, and colouration, but are usually white (sometimes pink) with a yellow column and brown to purple spots on the labellum.[5]
Ecology edit
T. variegata is an epiphyte that grows on the branches of trees and shrubs, including calabash, guava, citrus, and coffee plants. Flowering occurs in spring and fall.[3]
