Inflorescences emerging from the nodes of the leafy part of the stem, short, surpassing the leaves, laxly several- or many-flowered; peduncle thin, in the basal part covered with sheaths, 1.1-1.5 cm long, with a few small, tubular, keeled scales; rachis angular, 1-2.6 cm long. Floral bracts patent, triangular, subulate-acuminate, concave, 0.15-0.25 cm long. Flowers turned to all sides, 0.45 cm wide, 0.4 cm long. Sepals widely patent, at the base connate, outside papillose. Median sepal orbicular-ovate, obtuse, 1-nerved, almost 0.25 cm long, 0.23 cm wide. Lateral sepals not decurrent, orbicular-ovate, slightly acuminate, obtuse, 1-nerved, almost 0.25 cm long and wide.

Lip attached to the base of a pouch-like structure; the pouch much larger than the column, carnose, open and angular-truncate above, in the basal part prolonged and rounded-truncate, in frontal view rectangular, in lateral view obconical, in front almost flat and densely papillose-puberulous, 0.17 cm high, 0.13 cm wide; lip porrect, slightly incurved, entire, linear-ligulate, when flattened 0.23 by 0.07 cm, rounded, concave, convex below, inside and along the margins densely puberulous, 1-nerved.
