On the basis of morphological, ana- tomical, and karyotypic evidence, a change in status is proposed for Whytockia wilsonii (A. Weber) Y. Z. Wang, which is elevated from varietal to species level. Further, the affinity of another variety currently accepted within W. tsiangiana is recognized, and it is now transferred from W. tsiangiana as the new combination W. hekouensis var. minor (W. W. Smith) Y. Z. Wang. Illustrations of W. wilsonii are included along with morphological descriptions and diagnostic characters. The relationships of these and related species are discussed as well as geographic distribution. A key distinguishing these species is provided.
