This species is closely related to S. anomala in the continental China, but the latter is distinguished from this species, by having thicker twigs, larger terminal buds, oblong leaves, shorter and imbricate calyx lobes, and more stamens.The leaf shape is very variable, and it is hard to regard these forms as significant taxa.
