Description
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.
