Sepals and petals similar, narrowly long, open, half open, or closed; labellum suberect, base without spur, unlobed or 2- or 3-lobed; column slender, clavate, wingless; clinandrium +/- protruded, entire or serrate; anthers inconspicuously 2-loculeed; pollinia 2, 2-lobed or 4-lobed, granular-farinaceous, composed of dividable masses; caudicle extremely short or absent, without viscidium; rostellum short; stigma 1, below rostellum.

Plants can be maintained in cultivation provided great attention is paid to the need for a dormant period after the leaf matures, and a further dry period after flowering. The leaves are more attractive subjects for cultivation than the flowers. The tubers should be planted in a well-drained but moisture- retentive compost, and the pans kept in a suitable place depending on the origin of the tubers - grassland species usually require les s shade than those collected from thicket or forest.,
