A new species from Taiwan, Swertia changii S. Z. Yang, C. F. Chen & C. H. Chen (Gentianaceae), is described and illustrated. This species is so far known only from the southern part of the Central Mountain Range at elevations of ca. 800-1,300 m. The new species is most similar to S. shintenensis Hayata, which is endemic to northern Taiwan, but differs in having 4-merous flowers, axial corolla lobes purple, green nectaries, and smaller protrusions of the epidermal cells on the seed coat.
