Floral bract clasping the much smaller ovary, acuminate, concave, membranous, furfuraceous-punctate, 0.33 cm long. Flower 0.67 cm long. Median sepal porrect, making an acute angle with the lateral sepals, lanceolate, gradually subulate-acuminate, conical-acute, concave, 3-nerved, 0.7 by 0.18 cm. Lateral sepals forming with the column-foot a very short, rounded mentum, 3-nerved; facing margins cohering over the full length; synsepal at the base subovate, lanceolate-triangular with the apex thickened, concave 0.65 by 0.28 cm. Petals very small, appressed to the column, subobliquely oblong, pointed or slightly acuminate, 1-nerved, 0.23 by 0.07 cm. Lip erect, somewhat beyond the middle recurved, weakly 3-lobed, 3-nerved, when not flattened 0.16 cm long; when flattened in outline subrhombic, 0.18 by 0.14 cm; base with 2 small, very short, close-set keels; median part fleshy; lateral lobes erect, rounded, ciliate; mid-lobe triangular, obtuse, in the basal part finely ciliate, above papillose-serrulate, 0.07 cm long.
