Slender, erect or pendulous, epiphytic herbs without pseudobulbs, 30-45 cm. tall, the stems usually branching, the lower portions enveloped in the closely imbricating, papery leaf bases; the foliage of the apex 2-ranked. Leaves spreading, coriaceous, ligular, the apices usually retuse or rather unequally 2-lobed, very variable in size, 1-6 cm. long and .25-1.0 cm. wide (in our specimens 1.5-2 cm. long and about .3 cm. wide), the conduplicate bases closely imbricating and persistent, enveloping the stems. Inflorescences short, slender, 1-flowered scapes 10-15 mm. long, produced from the leaf axils. Flowers small. Sepals free, sub-equal, apparently not spreading, lanceolate, acute or obtuse, 9-11 mm. long and 2-2.5 mm. wide, the laterals somewhat obliquely inserted on the column foot, forming a short, rounded mentum. Petals subequal to the dorsal sepal, rather obliquely elliptic-oblanceolate, obtuse or shortly acute, 7-8.5 mm. long and 2-2.5 mm. wide. Lip obscurely 3-lobed, about 7.5 mm. long and 3.5 mm. wide when spread out, contracted at the base and articulated with the column foot, the lateral lobules or margins rounded, erect in natural position, the mid-lobe ovate to ligular, obtuse, about /2 the total length of the lip; disk with 3 parallel, thickened nerves, about /2 the length of the lateral margins. Column semi-terete, about 3.5 mm. long, produced at the base into a short foot.
