Piper brownsbergense and P. hirtilimbum are both pubescent with rather long hairs. P. hirtilimbum can be distinguished by the longer (to 2.5 mm) hairs on petioles and blades and the pubescent ovaries and fruits, whereas in P. brownsbergense the hairs on stem and petiole are at most 2 mm long and the ovaries and fruits are glabrous.
