 region, and not infrequent on old branches of Adansonia," Welwitsch, 674 !

Schweinfurth's Monbuttu specimen has a dwarf er scape and shorter capsules, so 

 that its identity is a little uncertain.

 very short. Leaves subradical, lanceolate-oblong or elliptic-oblong, 

 subacute or apiculate, 3-5 in. long, 10-13 lin. broad. Scapes 6-9 in.

Vpper Cruinea. Sierra Leone, cultivated specimens, Loddiges ! Ashanti : 

 Assin-Yan-Coomassie, on high trees, Cummins ! 



The side lobes of the lip are more rounded and auriculate in Cummins' Ashanti 

 specimens, but otherwise the two plants seem identical.
