Perianth glandular-pubescent; dorsal sepal uppermost, erect or more or less incurved over column, usually narrow; lateral sepals and petals sub-similar and stems spreading symmetrically. Labellum very shortly clawed, half-erect, undivided or three-lobed; margins often fringed or toothed; calli more or less clavate, in more or less regular longitudinal rows. Column elongate, erect to incurved, winged; anther terminal, apiculate, surface often papillose, pollinia 2 per cell, pollen finely granular; stigma discoid, inclined downwards; rostellum median.
