long as the erect sessile shortly-beaked ovary. Sepals sub-equal, linear, obtuse; the
lateral pair turned upwards and slightly spreading. Petals conniving with the dorsal
sepal to form a hood, falcately ovate-lanceolate, sub-acute, their bases oblique. Lip

shorter than the filiform lateral horizontally spreading lobes; spur variable, shorter
than the sepals and much shorter than the ovary, davate or fusifoi-m, curved.
Column very short, depressed. Anther-cells small, parallel, tubes none; pollinia small
obovoid, longer than the oblique caudicles ; gland sub-rotund, minute. Stigmas two
narrowly oblong, situate at the sides of the mouth of the spur; staminodes on
