Petals obliquely ligulate, obtuse, distinctly shorter than the sepals. Lip in outline oblong, concave at the base, in front rounded, obtusely apiculate, 0.35 by 0.2 cm, at the base with a forked lamella which is dorsally spur-like folded, the arms of the lamella gradually diverging, in the middle of the blade decurrent and disappearing. Column short, without rostellum. Anther reniform, in front 2-apiculate, with a reniform, calliferous umbo. Ovary with pedicel clavate, glabrous, 0.5 cm long. (After Schlechter, 1911-1914)
