Allied to A. hicandatum, Lindl., and A. fimhriatum, Rendle. Flowerless speci- 

 mens collected at the Nun River, Niger Delta, by Barter ! are very similar in habit 

 but probably belong to a different species.

Flowered in Messrs. Loddiges' Nursery in 1839. The Angolan plant cited here 

 by Reichenbach belongs to the next species.
