Petals 0.1 cm long and wide, suborbicular or obovate. Lip about 0.2 by 0.1 cm, 3-lobed, with a high, transverse lamella between the lateral lobes, the lamella with a notch in the middle to which the apex of the rostellum extends; lateral lobes obliquely broadly triangular, rounded, clasping the column; mid-lobe 0.05 by 0.08 cm, more or less hemispherical, deeply concave-saccate, fleshy; spur about 0.15 by 0.05 cm, cylindrical, obtuse.
