Var. sudanica may possibly be a distinct species, but as only fruiting si)ecimon8 

 are known it seems preferable to retain it for the present as a variety. 



U. Oiiignardi was described by Beille as having " liispidulous filaments," thus 

 differing from U. guineensis by this character. The filaments in bis type, liowever, 

 .are (juite glabrous and his plant is indistinguishable from typical U. guineensis.
