Small, erect, epiphytic herbs up to about 25 cm. tall, with clustered, elliptic-oblong, compressed, monophyllous pseudobulbs 12-18 mm. tall and 8-12 mm. wide, the bases enveloped in several imbricating bracts, the upper pair of which is usually foliaceous. Leaves coriaceous, grayish green, ligular to elliptic-lanceolate, acute, 7-16 cm. long and 2-3.5 cm. wide, contracted below into elongate, slender, conduplicate petioles. Inflorescences usually 6-8 slender, 1-flowered scapes 3-4 cm. long, produced from the base of the pseudobulbs. Flowers of moderate size, but large in relation to the size of the plants. Sepals subequal, free, spreading, white, linear-lanceolate, abruptly acute, 17-20 mm. long and 4-5 mm. wide, the oblique bases of the laterals inserted on the elongate column foot, forming a conspicuous acuminate mentum. Petals subequal to the dorsal sepal, white, from an oblique base lanceolate-acuminate, 15-17 mm. long and 4-5 mm. wide. Lip canaliculate, reddish brown, obscurely 3-lobed near the apex, oblong-obovate, about 12 mm. long and 6 mm. wide when spread out, contracted at the base and articulated with the foot of the column, the lateral margins erect, the apices rounded, mid-lobe ovate, acute, about Y4 the total length of the lip, conspicuously thickened and with a tubercle on the under-surface of the apex; disk with a fleshy linguiform callus, about % the length of the lateral margins. Column short, stout, semi-terete, somewhat arcuate, produced at the base into a long narrow foot.
