Bentham quotes under this species some specimens collected by Vogel on the 
Nun River, Niger Territory. These, however, be'ong to a distinct species, having 
quite a different habit and ovate-orbicular leaves only 5-7 lin. long. Bentham 
ives the length of the leaves as 1-1} in., which applies to Heudelot’s specimen, so 
sty retained his specific name for this, and have called the other species L. 
ogelit.
