Sepals very fleshy, the dorsal sepal free, concave, arching over the column, laterals con-nate at the base, forming a. conspicuous mentum. Petals much narrower than the sepals. Lip 3-lobed, the lateral lobes erect with spreading apices, mid-lobe rec-tangular or ovate, longer than broad, truncate or obtuse, strongly reflexed, with ciliate margins. Column short, subclavate, obtuse, winged. Anther terminal, operculate, imperfectly 2-celled; pollinia 2, waxy.
