As presently delimited, Corallodiscus lanuginosus includes seven taxa recognized in FRPS (Fl. Reipubl. Popularis Sin. 69: 233-245. 1990). Morphological variation in the present delimitation of C. lanuginosus includes indumentum (amount and type), leaf blade shape, size, margin, and texture, and flower number and size. The extent of this variation accounts for more than a few taxa previously described. However, in reexamining of all of these taxa, it became clear that the variation in all of these characters is continuous and is not correlated with the variation in other characters. For this reason it was impossible to clearly delimit previously recognized taxa. Thus, we recognize one, highly variable species, but further studies are needed to understand the variation.

The specimens from Xizang (Gyirong, Nyalam) and W Yunnan (Baoshan) differ from those of other areas in having the leaves entire or subentire, ovate or rarely obovate, flat or very rarely slightly plicate, submembranous or thin papery, and glabrous or nearly so adaxially. They probably represent a subspecies of Corallodiscus lanuginosus or an independent species.
