Tainia, commonly known as ribbon orchids[3] or 带唇兰属 (dai chun lan shu)[4] is a genus of about thirty species of evergreen, terrestrial orchids in the (family Orchidaceae) distributed from India, China, Japan, Southeast Asia to New Guinea, the Solomon Islands and Queensland.[1]

Description

[edit]

Orchids in the genus Tainia are evergreen, terrestrial herbaceous plants with upright, crowded, thin fleshy pseudobulbs. Each pseudobulb has a single, smooth or pleated leaf. The flower stalk emerges from the pseudobulb on the top of a leafless shoot and bears resupinate yellowish, brownish, red or purple small to moderately large flowers. The sepals and petals are similar in size and shape to each other and several flowers open simultaneously. The labellum is sometimes lobed but always has prominent ridges on its upper surface.[3][4][5]

Taxonomy and naming

[edit]

The genus Tainia was first formally described in 1825 by Carl Ludwig Blume who published the description in Bijdragen tot de flora van Nederlandsch Indië.[1][6][7] The name Tainia is an Ancient Greek word meaning "ribbon", "fillet", "band" or "stripe"[8] but Blume's reason for giving this name is not known.[5]
