Inflorescences short, 1-flowered scapes, solitary or in dense fascicles in the axils of the leaves. Flowers of moderate size. Sepals free, subequal, spreading, yellow, elliptic-lanceolate, acute, 10-12 mm. long and 4-6 mm. wide, the laterals somewhat oblique, the bases adnate to the column foot, forming an inconspicuous, rounded mentum. Petals lanceolate, acute, yellow, 8-10 mm. long and 2.5-3.5 mm. wide. Lip entire or obscurely 3-lobed, yellow with purple or maroon markings, ehliptic-ovate, acute, 9-11 mm. long and 4-5 mm. wide when spread out, the base contracted and articulated with the column foot, the lateral margins erect in natural position, the mid-lobe thickened at the apex and on the margins, about Y2 the total length of the lip; disk with a ligular callus running the full length of the lip, somewhat thickened near the apices of lateral margins. Column short, stout, somewhat arcuate, produced at the base into a short foot.
