Sepals similar, subequal, connivent, subcampanulate, paral- 
lel, with more or less arcuately spreading apices; dorsal sepal 
concave, adnate to back of column above base; lateral sepals 
with an oblique base adnate to short, decurrent column-foot. 
Petals linear, agglutinate with dorsal sepal. Lip with a distinct, 
flat claw without thickened margins and with a calliferous or 
incrassate, auriculate to cordate base and a fleshy, more or less 
papillose apical part. Column slender, arcuate, somewhat 
widened towards apex, at base produced in a sharply curved, 
decurrent foot; stigmata 2, confluent; rostellum from a narrowly 
cuneate base sinuously linear-triangular, acuminate. Anther 
ovate-cordate, acute; pollinia clavate with a short, linear-oblong 
viscidium. Ovary cylindric to fusiform, somewhat twisted. 
Terrestrial, slender plants. Roots fasciculate, fleshy tuberous. 
Leaves either synanthous or hysteranthous, distinctly petiolate. 
Stem erect, vaginate, terminated by a loosely few- to many- 
flowered spike. Flowers small to medium, spirally arranged or 
quaquaversal.
