Remusatia yunnanensis (H. Li & A. Hay) A. Hay is a herbaceous species which has thus far been considered endemic to Yunnan, China. In this study, we document the discovery of this species in Nantou County, Taiwan. R. yunnanensis is similar to Remusatia vivipara (Lodd.) Schott and only distinguishable by the difference in spathe limb color. R. yunnanensis exhibits a distinct purple red spathe limb color while that of R. vivipara is yellow. The description and illustration of R. yunnanensis, including a dichotomous key description for Remusatia in Taiwan are provided in the present study.
