In this paper, a new record Viola species of Taiwan, V. kwangtungensis Melch., is reported. This newly recorded species was found at elevations of 1300~1600 m in Taiwan, growing in shady soil on a slope under a bamboo plantation. It is similar to V. mucronulifera Handel-Mazzetti and V. formosana Hayata var. kawakamii (Hayata) Chen & Yang, as well as V. adenothrix Hayata var. adenothrix and V. nagasawae Makino & Hayata var. pricei (W. Becker) Wang & Huang. Detailed differences in diagnostic morphological features of these species are discussed in this paper.
