Erect or pendulous, epiphytic herbs. Pseudobulbs strongly ancipitous, oblong- elliptic, monophyllous, 3-4 cm. long and 1.0-1.5 cm. wide, approximate and often more or less imbricating, obliquely inserted on the rhizome, the bases provided with several imbricating bracts, the upper 1-3 of which are conspicuously long- foliaceous, the short internodes enveloped in closely imbricating, more or less complanate, persistent, acute, papery bracts. Leaves subcoriaceous, linear, acute or acuminate, 25-40 cm. long and .6-1.0 cm. wide, contracted below into very short, conduplicate petioles. Inflorescences usually solitary, slender, 1-flowered scapes 3-4 cm. long, produced from the base of the mature pseudobulbs. Sepals subequal, free, more or less spreading, lanceolate, acute, white with red markings, about 1.5 cm. long and .3-.4 cm. wide, the laterals adnate to the column foot, forming an inconspicuous, subacute mentum. Petals subequal to the dorsal sepal, lanceolate, acute, white, about 12 mm. long and 2.5-3 mm. wide. Lip oblong- ligular, acute, 3-lobed near the apex, about 12 mm. long and 5 mm. wide when spread out, the base articulated with the foot of the column, the lateral lobes erect in natural position, dark red, the mid-lobe ovate, subacute, somewhat thickened, about /3 the total length of the lip, yellow, the upper surface and margins minutely papillose-puberulent; the disk with a linear, obtuse, fleshy callus, about 3/4 the length of the lateral lobes.
