This most widely distributed species in the genus is very highly polymorphic in the shape, size, and apices of the leaves. The apices of the leaves are highly variable, but the variation seems to be continuous. The bases of the leaves are usually subcordate, and seemingly the most stable diagnostic character for this species. The plants from Taiwan are more narrowly oblong-elliptic, but show no essential differences from those of Fujian, Guangdong, and Jiangxi. From the subcordate leaf bases of the Taiwan plants, it seems more reasonable to refer them to Stachyurus chinensis than to S. himalaicus. These two species are usually distinguishable by leaf shape, particularly the leaf base, but the plants from SW Sichuan, SE Xizang, and NW Yunnan cannot be distinctly differentiated from those of the Himalayan region. In a broader sense, the two species may be better treated as conspecific.
