Upper Guinea. Sierra Leone. First described from specimens which flowered 

 with Messrs. Loddiges, of Hackney, in 1840. 



Var. purpnreum, Rolfe. Sepals purple, except at the base, otherwise quite typical. 



TTpper Guinea. Sierra Leone, Scott-Elliot ! "Flowered at Kew in 1892. 



It is rather singular that this species is only known from garden specimens, which 

 appear to have been sent home on several different occasions. B. Drallei, Reichb. f., 

 is identical.
