This is referred to U. rigida with some reserve owing to the 
somewhat different aspect of the original plant, which presents 
a stouter flowering scape and somewhat more robust vegetative 
branches. Fruiting specimens, however, collected by Barter on 
Sugarloaf Mountain near Freetown, Sierra Leone, connect the 
two forms in a way suggesting ecological differentiation rather 
than genetic. Samples collected by Chevalier between Yinba 
and Kouria in French Guinea represent exactly the same condi- 
tion as Mr. Lely’s. The latter describes the flowers as white. 
In the dry state as received they are decidedly yellow and this 
colour oir more pronounced on boiling. 
U. rigida is an isolated type among the African species of 
wiculaeia as far as they are known, and approaches most 
closely the Brasilian U. neottioides. It has no bladders and the 
plants are attached by hapters to the rocks or boulders of swift 
streams or cataracts—(O. Stapf.)
