Stamens usually 3; filaments very short; anthers reniform. Female spikes 4-6 cm; peduncle, rachis, and bracts as in male spikes. Ovary subglobose; stigmas 4. Drupe globose, ca. 2 mm in diam. Fl.

There is considerable variation in the indumentum, from densely puberulent to nearly glabrous. This species has been more widely known as Piper puberulum or as P. arboricola. The name P. puberulum is a later homonym of the Fijian species P. puberulum, and is thus not available; the material with few hairs was identified as Piper arboricola in FRPS, but examination of the type of that name has shown that it is a synonym of P. kadsura.
