Strobilanthes danxiaensis , a new species endemic to the Danxia Mountain region of Guangdong, China, is described herein. Phylogenetic analysis based on nuclear ITS sequences indicates that S. danxiaensis , S. japonica , S. tetrasperma and S. austrosinensis form a well-supported clade. Morphologically, S. danxiaensis is most similar to S. tetrasperma and S. austrosinensis ; however, it is readily distinguished from S. tetrasperma by its longer corolla, much broader oblong–obovate and emarginate corolla lobes, and a longer style. It further differs from S. austrosinensis in having larger oblong–obovate, emarginate corolla lobes, shorter filaments, and a longer style. The integration of morphological and molecular evidence supports the recognition of S. danxiaensis as a distinct species.
