Dorsal sepal subovate or narrowly elliptic, ca. 5 × 2–3 mm, 1-veined, outer surfaces almost glabrous; lateral sepals falcate, similar to dorsal sepal, but somewhat wider. Petals linear to linear-ligulate, slightly oblique, ca. 4.5 × 1 mm, dilated toward apex, glabrous, 1-veined; lip obovate, 8.5–15 × 6–10 mm, narrowing to ca. 4 mm wide at base, apex deeply 2-lobed; lobes diverging at an acute angle to one another, broadly oblong to subsquare, 2–2.5 × 2–3.5 mm, margins minutely ciliate, apices truncate-rounded and slightly undulate or crenulate; disk with minute papillae. Column slightly arcuate, ca. 4 mm; anther inclined toward rostellum, ca. 0.7 mm; stigma concave, suborbicular, with slightly exserted margins; rostellum subsquare or broadly oblong-ovate, large, ca. 0.7 mm.
