A very distinct species, and the first of the African forms of Maprounea to find 
its way into European herbaria, where it has been treated independently by Baillon 
and by Miiller as a state of the American M. guyanensis, Aubl. It is, however, a 
Pax and Hoffmann explain, more nearly related to WM. africana, Miill. Arg. From 
that species, however, it differs so greatly in its seeds, and in other respects, that it 
seems preferable to treat it as deserving independent recognition.
