Sepals subequal, free, usually widely spreading. Petals like the 

 sepals or narrower. Lip usually more or less adnate to the column ; 

 limb spreading, 3-lobed, with the terminal one often deeply bilobed, disc 

 variously callous or lamellate ; base mostly extended into a slender spur 

 (in the African ones invariably so). Column short, T^ithout a foot ; 

 wings usually united to the sides of the column. Anther subterminal, 

 operculate, incumbent, 2-celled; pollinia 8, oblong or obovate, some- 

 what compressed, the caudicles often somewhat attenuate and united by

 with short leafy stems, sometimes pseudobulbous at the base. Leaves 

 2 to several, petiolate ; limb elliptical- to oblong-lanceolate, acute
