A very distinct species, nnd the first of the African forms of Maprounea to find 

 its way into Eiuopean herbaria, wheie it has been treated independently by Baillon 

 and by Miiller as a state of the American M. guyanensis, Aubl. It is, however, as 

 Pax nnd Hoffmann explain, more nearly related to M. africana, Miill. Arg. From 

 that species, however, it differs so greatly in its seeds, and in other respects, that it 

 seems i)referable to treat it as deseiving independent recognition.
