Inflorescences terminal, capitate, nodding, 6-flowered, when young enveloped by a spathe. Spathe ovate, concave, transparent, glabrous, 1 cm long, apex acuminate, margin incurved or spathe leaf-like; floral bracts triangular, thin, transparent, strongly concave, with brown dots, 0.5-0.63 cm long, 0.3-0.4 cm wide, 3-nerved, apex narrowly obtuse. Flower upright, glabrous, 0.65 cm long, 0.6 cm in diameter. Median sepal ovate, strongly concave, 3-nerved at base, 5-nerved in higher parts, 0.55-0.57 cm long, 0.37-0.40 cm wide; apex obtuse, shortly obtusely apiculate, recurved. Lateral sepal obliquely broadly triangular, 3-nerved at base, 4-nerved in higher parts, 0.45-0.65 cm long, 0.38-0.40 cm wide; apex shortly acutely acuminate, recurved; base decurrent on the column foot, 0.33 cm connate, with mentum; mentum saccate, acute angle with the ovary, dorsally impressed, weakly 3-lobulate, 0.4 cm long, entirely clasping the spur. Petals oblong-subobovate, 3-nerved, glabrous, 0.5 cm long, 0.26 cm wide, 3-nerved; apex obtuse, recurved; base shortly narrowed. Lip subovate, not clasping the column, only the base adnate to the column, 0.13 cm long, 0.18 cm wide; epichile weakly 3-lobed, mid-lobe porrect, forming a right angle with the spur, subovate, obtuse, apex obtusely convex, with brown glands mostly in the apical part; lateral lobes indistinct, erect, lightly rounded; hypochile with transverse, fleshy, rounded, decurved lamella, spurred; spur oblong, laterally compressed, glabrous, making right angle with the ovary, 0.35-0.38 cm long, 0.18 cm wide, apex broadly obtuse. Column curved, club-shaped, with column foot, making an obtuse angle with ovary, 0.28-0.29 cm long, base 0.1 cm adnate to the lip; clinandrium triangular, obtuse tooth; stelidia triangular. Anther cucullate, suborbicular, apex retuse, membranous-marginate, connective conical thickened, 0.1 cm long; rostellum large, transversely quadrangular, subretuse, surpassing the stelidia; stigma semiorbicular, lower margin strongly elongated, recurved; pollinia not seen. Ovary cylindric, curved, glabrous, 6-ribbed, 0.41-0.90 cm long. Capsule not seen.
