Tolumnia variegata, commonly known as the harlequin dancing-lady orchid or variegated oncidium in English and as angelito or angelitos in Spanish, is a species of orchid native to the Caribbean.[1]
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]
