Small, epiphytic, pseudobulbose herbs, the plants reminiscent of a Notylia in habit. Leaves flat, ligular to lanceolate, fleshy or coriaceous. Inflorescences nodding or pendulous racemes, produced from the base of the current pseudobulb. Flowers of moderate size or sometimes rather small, on slender pedicels subtended by small bracts. Sepals subequal, free, more or less spreading. Petals similar to the sepals or a little smaller. Lip continuous with the base of the column, erect, deeply 3-lobed, the lateral lobes rather broad, erect, embracing the column, the mid-lobe spreading. Column erect, subterete, wingless, footless, the apex sulcate, the rostellum slender, erect or slightly inclined, the clinandrium broadly cupulate, with fimbriate or dentate margins. Anther erect at the base of the clinandrium, oblong, imperfectly 2-celled, produced into a long appendage embracing the rostellum; pollinia 2, waxy.
