Erect epiphytic herbs, 30-50 cm. tall, the stout complanate-cylindric canes enveloped below in the broad persistent leaf bases, the base of the cane often with one or more oblong-elliptic, compressed pseudobulbs, 2.5-3 cm. long and 1.5-2 cm. wide. Leaves coriaceous, spreading, 2-ranked and equidistantly distributed on the upper stem, the blades ligular, shallowly and unequally 2-lobed to acute, 7-27 cm. long and 1.5-3.5 cm. wide, the conduplicate bases closely imbricating. Inflorescences slender 1-flowered scapes, 6-9 cm. long, produced in dense fascicles from the leaf axils. Flowers small. Sepals subequal, free, spreading, white, lanceolate, acuminate, 10-12 mm. long and 3.5-4 mm. wide, the laterals somewhat obliquely inserted. Petals subequal to the sepals, rather obliquely lanceolate, acuminate, white, 9-10 mm. long and 2-3 mm. wide. Lip 3-lobed, shortly clawed at the base, red, 5-6 mm. long, the lateral lobes auriculate and erect, the mid-lobe spreading, oblong-elliptic, obtuse, about % the length of the lip; disk between the lateral lobes with a broadly obtuse, reniform, fleshy callus. Column short, stout, semi-terete, 2-2.5 mm. long, produced at the base into a very short foot.
