Notes

Piper perstipulare can be distinguished from P. coruscans and P. glabrescens, two other species with rather long-petioled leaves and relatively few secondary veins, by the following combination of characters: It has floral bracts that are densely marginally fringed and leaves that are appressed pubescent on the veins below, whereas P. glabrescens has glabrous floral bracts and the leaves below glabrescent. In P. perstipulare, the upper secondary veins ascend distinctly to the apex without anastomosing, whereas in P. coruscans they anastomose before reaching the apex. A striking difference with P. coruscans is that the stipules are longer than the petioles, whereas in P. coruscans they are shorter. Piper perstipulare has transverse tertiary veins, whereas P. coruscans has a less regular pattern.
