Synonyms:
Terrestrials or less often epiphytes, herbaceous. Stem reed-like or a corm or pseudobulb, with several internodes. Leaves convolute, distichous, plicate, usually articulate. lnflorescence lateral or rarely terminal, not branched, with spirally arranged flowers. Flowers resupinate, flat to campanulate or urn-shaped, often showy. Sepals and petals free, usually rather similar and spreading, occasionally porrect. Lip usually 3-lobed, sometimes saccate or with a spur; keels or calli usually present.

(after Cribb 2005)
Tribe Collabieae contains 18 genera, the majority confined to the Old World, a few entering the North Temperate regions of Asia; one genus, Calanthe, is pantropical with the centre of diversity in tropidcal Asia and has also has a few species in Africa, Madagascar, Australia, the the Americas (Mexico to Colombia and the Caribbean) and the Pacific.
