Caespitose, epiphytic herbs with erect or pendulous, flattened, foliaceous stems typical of the genus, 5-40 cm. long and 1-2 cm. wide. Leaves equitant, coriaceous, in profile narrowly triangular with obliquely truncate or obtuse apices, 0.8-2 cm. long and 0.3 5-1.0 cm. wide. Inflorescences simple 1-to 3-flowered scapes or abbreviated, few-flowered panicles up to about 2 cm. long, produced from the central or subterminal leaf axils. Flowers small, yellow, on slender, filiform pedicels subtended by ovate-cordate, membranaceous bracts. Sepals subequal, free, spreading, concave, ovate to elliptic-oblong, acute and apiculate, 2.5-4 mm. long and 2-3 mm. wide. Petals broadly ovate to elliptic-ovate, obtuse, 2.5-4 mm. long and 1.5-2 mm. wide. Lip complexly 3-lobed, 2.5-5 mm. long and 2.5-5 mm. wide, the lateral lobes linear-ligular, obtuse, spreading or reflexed, the mid-lobe rhombic-obovate to obovate, the lateral margins obscurely lobulate, the apex deeply retuse, the disk with a low, slightly concave, more or less bifid callus.
