Dear,
Attached here the full description of P. citirfolia Hook. f.. in FBI.
Bangal Plants refers only one Paramignya - citrifolia
The photographs show 1) some leaves with acute and others abruptly obtusely acuminate apices, 2) filaments longer than anthers 3) filaments free, and one or two flowers with columnar disc?
So. I think we can see features of both citrifolia and griffithii. Perhaps this is the reason behind your latest lit. clubbing them together! In addition, you may like to go through Flora Indica.
Thanks n regards
