Lf. solitary, usually with a rather long sheath, linear, lanceolate or rarely nearly ovate: fls. usually several in a terminal raceme, sometimes reduced to 1 or 2, blue, purple, red, or yellow, occasionally with white varieties; sepals and petals nearly equal, spreading; labellum similar; column erect, broadly winged, the wings variable, sometimes extended into a broad lobed hood over the anther, lateral lobes often penicillate or crested: caps. erect, obovoid or oblong, beakless. About 30 species, Austral., New Zeal., New Caledonia, and Malaya. Cult. similar to that of bletia. None of the species is in common cult., but a number of them are of interest to orchid fanciers.
