P. macrantha is closely akin to P. glabra Donn. Sm., but may be recognized by 
its ovary which is minutely villous-tomentose apically and at base of style, 
and by its larger flowers with stamens up to 4.5 mm. long, and petals up to 
9mm. long. Both P. macrantha and P. glabra have similar indument of branchlets 
and young leaves, as well as leaves black-punctate mostly in sharp irregular 
lines.
