Erect terrestrial herbs with 2-3, usually linear-lanceolate, acuminate, plicate, strongly veined leaves which are ultimately deciduous. Leaves 25-60 cm. long and 0.8-2.5 cm. wide, the basal portions contracted into a sheathing petiole enveloped in 2-3 short, tubular, leafless bracts which are produced from the apex of a short, subconic, corm-like pseudobulb averaging about 1.5 cm. in diameter. Inflorescences erect, the basal portions enclosed in the sheathing leaf bases, the terminal portion an unbranched raceme equaling or exceeding the leaves in length. Flowers relatively large and conspicuous, in our specimens described as being purplish rose, produced on slender pedicels subtended by ovate, acuminate bracts. Sepals free, spreading, subequal, lanceolate, acute, 3-3.2 cm. long and .7-.9 cm. wide, the dorsal usually somewhat narrower. Petals subequal to the dorsal sepal, oblanceolate, acute, 3-3.5 cm. long and about .7 cm. wide. Lip 3-lobed, about 3 cm. long and 2-2.2 cm. wide when spread out, the lateral lobes rounded, erect in natural position, the mid-lobe entire, obtuse, spreading, about 8 mm. long and 8 mm. wide. Inner lip (disk) with 5 fleshy longitudinal crests. Column slender, semi-terete, 2.3-3 cm. long, somewhat dilated at the apex.
