Notes

Glabrous plants with pubescent fruits mark the species. It is difficult to identify collections without mature fruits.
Piper fanshawei can easily be mistaken for P. cuyunianum Steyerm. (1984: 391) from SW Venezuela, but differs in having pubescent fruits whereas P. cuyunianum has glabrous fruits.
Piper fanshawei differs from P. bolivaranum in the wider leaves: in P. fanshawei 3-4.5 cm wide, in P. bolivaranum 0.7-1.5 cm; P. bolivaranum also has glabrous — not pubescent — fruits.
