length spreading, the median free, the lateral broader, at tin 1

 into a cup, the blade erect-spreading, 3-lobed. Column short, 

 with the dilated margins connate with the lip into a cup : 

 clinandrium short. Anther terminal, opercular, incumbent, 

 with four parallel cells; pollinia 4, waxy, ovoid, distinct, 

 without an appendage, on the dehiscence of the anther connected 

 at the apex by a sparse viscid substance. Capsule ovoid or 

 Bubglobose, not beaked, the ribs winged.

Epiphytic herbs, with fleshy generally oblong pseudobulbs, 

 not, however, present in the Jamaican species, which have a few 

 sheaths, and at the apex one or two leaves. Leaves somewhat 

 leathery, not plaited. Peduncles terminal, almost always only 

 one-flowered, with a few sheaths at intervals. Bracts like the 

 sheaths, the uppermost spathaceous. Sepals almost equal, free, 

 spreading. Petals wider than the sepals. Lip erect at the 

 base of the column ; lateral lobes enclosing the column : the 

 median lobe spreading. Column rather long, narrowly 2-winged; 

 clinandrium crenulate. Anther attached to a posterior tooth, 

 opercular, incumbent, convex, distinctly 2-celled, each cell
