lanceolate or oblong, more or less retuse at the apex, rigid- 
ly membranaceous to subcoriaceous. Inflorescence a ter- 
minal densely or loosely flowered unilateral or distichous 
raceme of one to many flowers. Floral bracts short or 
elongated, suborbicular to oblong, paleaceous. Flowers 
small, variously colored from nearly white to deep rose- 
purple, with short pedicellate ovaries, often partly con- 
cealed by the subtending bracts or upper leaves. Sepals 
subequal, erect or recurved, concave, varying from free 
to coherent almost to the apex, gibbous at the base under 
the lip, more or less dorsally carinate along the mid-nerve 
or occasionally broadly winged on the back (especially the 
lateral ones), free part elliptic to lanceolate and obtuse to 
subacuminate. Petals with a slender claw, a little shorter 
and broader than the sepals, ecarinate, oblique, oblong- 
lanceolate, elliptic or obovate. Lip with a short claw, 
subequal to the petals but narrower, adnate to the base 
of the column or the short column-foot, linear to linear- 
oblanceolate, obtuse to acute, commonly sigmoid-flexu- 
ose below or slightly above the middle or both, sometimes 
constricted near the middle, variously marked on the claw 
and at about the middle of the lamina. Column erect, 
semiterete, wingless, toothed at the apex, apparently 
footless or produced at the base into a short inconspic- 
uous foot; anther terminal, operculate, incumbent, 2- 
celled; pollinia four, waxy, ovoid-oblong, elongated and 
laterally compressed. Capsule small, ellipsoid or ovoid.
