There was confusion in the application of this name in FRPS, with the records divided between
Piper martinii and
P. wallichii. These records have been consolidated within
P. wallichii as defined here. Y. C. Tseng believes that material from Emei Shan, Sichuan, with relatively broad, subpalmately veined leaves, should be recognized as a distinct species. M. G. Gilbert and N. H. Xia believe that such material is better regarded as a form that has flowered prematurely on normally sterile climbing stems.
