An examination of the holotype clearly shows that this 
species is a member of the genus Triphora and closely related 
to T. amazonica Schltr.

At the time Schlechter described S. Powellii, the type of S. 
Fenzliana was not available to him, judging from an ex char. 
determination of a drawing he sent to Professor Ames. An 
examination of the holotype of both species confirms their 
conspecificity. Recently I have seen material of this species 
also from Colombia and Ecuador.
