    Southeastern mainland China. Taiwan, at edges of broad-leaved forests, 50-1,500 m.

    This species is closely related to V. andersonii and was previously treated as a variety of it. It differs in having nonglandular, stellate hairy leaves (vs. leaves with straight hairs and glands), a densely pubescent involucre (vs. involucre hairy on the margins only) and florets ca. 10 (vs. florets ca. 20) per head.
