攀援藤本，长达数米；幼枝被柔软的短毛，老时脱落。叶硬纸质，卵状披针形或卵形，长5-11厘米，宽2-6厘米，顶端短尖或渐尖，基部浅心形或半心形，两侧常不对称，两面被柔软的短毛，毛少部分分枝，老时腹面近无毛；叶脉5-7条，最上1对互生，离基1.5-3厘米从中脉发出，余者均自基部或近基部发出；叶柄长5-10毫米，密被短柔毛，仅基部具鞘。花单性，雌雄异株，聚集成与叶对生的穗状花序。雄花序纤细，长约7厘米，直径约3毫米；总花梗比叶柄稍长，其与花序轴同被疏柔毛；苞片圆形，有时基部略狭，盾状，无毛；雄蕊通常3枚，花药肾形，2裂，花丝极短。雌花序长4-6厘米；苞片、总花梗和花序轴与雄花序的无异；子房近球形，柱头4。浆果球形，直径约2毫米。花期3-5月。
产于广西、广东及其南部沿海各岛屿。生于疏林或密林中，攀援于树上或石上。模式标本采自广东南部沿海岛屿。

Climbers to several m long, dioecious. Young branches softly hairy, glabrescent. Petiole 5-7 mm, densely pubescent, sheathed at base only; leaf blade ovate-lanceolate or ovate, 5-11 × 2-6 cm, papery, abaxially pubescent, a few hairs dichotomous, adaxially ± glabrescent, base ± cordate, apex acute or acuminate, usually asymmetric; veins 5-7, apical pair arising 1.5-3 cm above base, alternate, others ± basal. Spikes leaf-opposed. Male spikes ca. 7 cm × 3 mm; peduncle slightly longer than petioles, pilose; bracts orbicular, sometimes slightly tapered, peltate, glabrous. 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. Mar-May.* Thickets or forests, on trees or rocks; 100-1300 m. Guangdong, Guangxi, Hainan
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.
