A new species of Berberis Sect. Wallichianae from Taiwan, Berberis morii.

In a revision of Berberis Sect. Wallichianae in Taiwan and Luzon, the Philippines, two of the authors recognized 11 species from Taiwan, including three new species. This article recognizes a further new species, Berberis morii, and places it in the same clade with other species from Taiwan. Rather than reproduce all the observations that were made there, we simply note that Taiwan is an important center of endemism of B. Sect. Wallichianae. In comparing the floral structure and overall morphology of B. morii with similar taxa from Taiwan, China and India, a series morphological differences, both qualitatively and quantitatively, were noted. Phylogenetic analysis was also used to evaluate the endemicity of B. morii. [ABSTRACT FROM AUTHOR]
