Lév. & Vaniot, but differs from the latter by its stems, branchlets and rachises with dense brown straight glandular long hairs, petioles short, leaf blades oblong ovate or subpandurate, apex of the leaf acute to acuminate, sepals triangular lanceolate, apex long caudate. R. opulifolius Bertol was found in the Gaoligong Mountains, northwest Yunnan; it is similar with R. idaeopsis Focke, but differs from the latter by its leaves 3-5 foliolate, inflorescences extremely short, less than 3 cm long, pedicels very short, and the racemes short head like.
