11. LISSOCHILUS, R. Br.; Benth. et Hook. f. Gen. Pl. iii. 536. 
Sepals subequal, free, spreading or reflexed, the lateral some- 
times adnate to the foot of the column. Petals erect, generally 
much larger and broader than the sepals, and differently coloured. 
Lip continuous with the foot of the column, more or less distinctly 
trilobed; base variously saccate or calcarate; side lobes erect or 
spreading; the middle one spreading or recurved; disc variously 
cristate, lamellate, or sometimes smooth. Column erect, clavate, 
more or less produced into a foot at the base; clinandrium oblique, 
erect, entire. Anther terminal, operculate, incumbent, semiglobose, 
conical or more or less bilobed at the apex, imperfectly 2-celled ; 
pollinia 4, ovoid, united in pairs, affixed to a broad stipes and gland. 
Capsules oblong or somewhat elongate, with prominent thickened 
angles.—Terrestrial herbs. Stems creeping, often thickened into 
rhizomes or tubers, leafy at the base. Leaves elongate, lanceolate 
or linear, plicate. Scapes usually tall, variously sheathed below, 
loosely racemose above. Flowers generally medium-sized or large, 
rarely small. Bracts small or narrow.—Hypodematium, A. Rich. 
Tent. Fl. Abyss. ii. 286, t. 83. 
A genus of about 100 species, most abundant in Tropical Africa, much less so in 
Extra-tropical South Africa, and with three or four representatives in the Mascarene 
Islands. It approaches Eulophia very closely, and has been reduced to it, but the 
majority of the species are very easily separated by the small spreading or reflexed 
petals, and the broad, often differently coloured petals.
