 Sepals ligulate- triangular. Petals lanceolate. Lip dilated above the 

 cuneate base, trifid above ; side lobes triangular ; front lobe with a

Sepals free, connivent or ultimately spreading ; lateral oblique, 

 often broader than the dorsal. Petals similar to the lateral sepals 

 or a little narrower. Lip continuous with the base of the column, 

 spreading, free ; claw broad, somewhat fleshy ; base sulcate or con- 

 cave but not calcarate ; apex contracted ; limb dilated, tridentate or 

 trilobed. Column short ; clinandrium erect. Anther erect or some- 

 what reclinate, broad ; cells parallel ; apex inferior, adnate to the short 

 side lobes of the rostellum ; pollinia granular ; caudicles short ; glands 

 large, contiguous ; staminodes lateral, small, rounded or auriculate. 

 Stigma pulvinate, fleshy or concave, often large; rostellum short, 

 trilobed ; middle lobe erect between the anther cells, somewhat plicate ; 

 side lobes short, suberect. Capsule narrowly oblong. — Terrestrial, 

 leafy herbs, with undivided, elongate tubers. Leaves sessile, generally 

 numerous and imbricate, gradually decreasing upwards into the bracts. 

 Spikes or racemes dense or many-flowered. Bracts lanceolate or ovate- 

 lanceolate, often rather large. 



A genus of about 10 species, limited to Continental Africa, chiefly diff"ering from 

 Platanthera in the absence of a spur to the lip. Bentham refers it to DisecB, where 

 it is clearly out of place.
