Floral bracts alternate in two rows, patent, amplexicaul, cyathiform, strongly laterally compressed, conspicuously keeled, acute, squamulose, 0.7 cm long. Flowers opening singly in succession, 2.5 cm wide. Median sepal narrowly lanceolate, obtuse, apiculate, concave, 7-nerved, at the base 5-nerved, 1.8 by 0.4 cm. Lateral sepals diverging at almost right angles, 2.2 by 0.75 cm; apex slightly incurved, obliquely oblong, especially to the apex conduplicate-cymbiform; acuminate with a laterally compressed apicule; outside strongly keeled. Petals small, diverging, obliquely oblong-triangular, acuminate, acute, 3-nerved, 0.475 by 0.2 cm. Lip large, oblong-spathulate, flat, 2 by 0.77 cm; base strongly excavate-concave, with 2 calli which in front turn in low ribs, with a deep longitudinal groove extending to about the middle of the blade; claw linear-oblong, convex, glabrous, 1.15 by 0.45 cm; blade ovate-orbicular, obtuse, convex, with incurved margin and apex, lengthwise with rows of small warts, in the middle papillose-tomentose.
