 Cymbidium. Willd, 



Fetals equal an^l connivent. Lip mostly pro- 

 duced at the base. Column free. Pollinia 4,

 mose; leaf radical or none; scape leafless, sheathed, ma- 

 ny-fiowered, flowers nutant, obscurely coloured. — (To this 

 genus Mr. R. Brown adds species furnished with an un-

 ric character; of the 3 enumerated below, one is destitute 

 even of any protuberance at ihe base of the lip.)
