  产四川、云南。生山坡林缘或沟边疏密林中，海拔1200-3300米。
  此种和毛萼莓R. chroosepalus Focke相近，区别在于本种叶片基部圆形至浅心形；叶柄长1-4厘米；花萼外密被灰白色绒毛。而后者叶片基部心形；叶柄长4-7厘米；花萼外密被灰白色或黄白色绢状长柔毛。两种易于区别。

Shrubs climbing, to 2 m tall, long stoloniferous. Branches grayish brown to dark reddish brown, glabrous, with sparse, somewhat curved prickles or nearly unarmed. Leaves simple; petiole 1–4 cm, shortly petiolate at bases of inflorescences, glabrous, with sparse, slightly curved prickles; stipules caducous, free, oblong or liguliform, 1–1.4 cm, glabrous or subglabrous, apex divided; blade broadly ovate, rarely ovate-oblong, 9–12 × 6–9 cm, palmately veined from base, abaxially densely gray tomentose, adaxially glabrous, base rounded to shallowly cordate, margin irregularly coarsely sharply serrate, apex shortly caudate. Inflorescences terminal, cymose panicles, much branched, pyramidal, to 10–22 cm; rachis and pedicels tomentose; bracts oblong or liguliform, rarely ovate, 1–1.2 cm, tomentose, apex divided. Pedicel 0.7–1.5 cm. Flowers 6–8 mm in diam. Calyx purple, abaxially densely gray tomentose; tube shorter, shallowly pelviform; sepals erect or reflexed after anthesis, ovate or ovate-lanceolate, 4–6(–7) × 2–3 mm, margin entire, rarely with 2 or 3 teeth, apex acuminate. Petals usually absent. Stamens many, in 1 whorl, shorter than sepals; filaments linear, glabrous. Pistils slightly shorter than stamens, glabrous. Aggregate fruit black at maturity, subglobose, less than 1 cm in diam., glabrous. Fl. Jun–Jul, fr. Aug–Sep.
