Petals erect next to the rostellum, narrowly oblong, acute, falcate, 2.5-4 mm long, fleshy along midrib, with a small basal anticous lobe. Lip patent, oblong to elliptic, obtuse, 3.5-5 mm long. Anther horizontal; stigma front margins taller than and curved over the receptive surface; lateral rostellum lobes square, a deep groove between them, central lobe small.
