While plants in cultivation and herbarium specimens recently collected in Vietnam generally have 10-11 stamens, the type has 15, suggesting an affinity with R. maddenii. Vegetatively there is a similarity with R. nuttallii, with which it grows in the wild, but the leaves are narrower than those of the latter species. Royal Horticultural Society (1997)
