A plant from Lagos which flowered at Kew in 1891 may be a form of this species.

Upper Guinea. Sierra Leone. Flowered in the collection of the Horticultural

Only known to me from the description and a sketch in Lindley’s Herbarium. The 
author speaks of it as a curious little plant formerly cultivated in the collection of the 
Horticultural Society, but now lost, adding: “It is frequently sent from Sierra Leone 
mixed with other epiphytes, and is, I should think, very common in that colony.”
