Petals obliquely suborbicular-spathulate, broadly obtuse, about 0.08 cm long. Lip as long as the sepals; claw square-clawed, somewhat concave; blade abruptly dilated, semi-orbicular, broadly obtuse, 0.06 cm long, at the base 0.1 cm wide. Column short; rostellum bidentate, as long as the low clinandrium. Anther reniform-cucullate, umbonate; pollinia obliquely obovoid; stipe about half as long, linear; viscidium very small, orbicular.
