Like many widely diffused species, this is very polymorphic, and some of the form* 

 at first sight appear distinct, though, after examining them many times, I have failed 

 to find any distinguishing characters. Even tl)e Angolan one, foruicrly considtre«l 

 distinct, whose leaves sometimes attain a length of 3\ inches, seems to pass into //.
