Flower structure for this genus can be described as globose, nonresupinate flowers that are white to yellow, mostly unspotted, and borne on an erect inflorescence. The epichile is rectangular or ovate (not triangular as in Houelltia), and the lateral projections on the hypochile are broad instead of acute. The

has a broad, concave viscidium.
The plants have ovoid, ridged pseudobulbs, each bearing 2-4 large, pleated leaves. The inflorescences begin from the base of the pseudobulbs and are always pendant, with fleshy, showy flowers hanging downward ("nodding") on a simple raceme. The dorsal sepal is free and the lateral sepals form a short mentum with the column foot. The petals are similar to the dorsal sepal but smaller. The lip is deeply 3-lobed, the lateral lobes are upcurved and the mid-lobe is spreading. The anther is imperfectly two-celled and there are two waxy pollinia, cleft, with viscidium and a prominent stipe.
