Abstract

The phylogenetic relationships between species of the genus Dumasia have been revealed by previous studies. However, some taxonomic problems still remain to be resolved. In this article, we recognize 10 species of Dumasia. We re-circumscribe D. yunnanensis Y. T. Wei & S. K. Lee, promote D. nitida var. kurziana Predeep & M. P. Nayar as a distinct species, and synonymize D. hunanica Y. K. Yang, L. H. Liu & J. K. Wu with D. hirsuta Craib. D. prazeri Predeep & M. P. Nayar is here confirmed as a newly recorded species for China, and D. zhangjiajieensis Y. K. Yang, L. H. Liu & J. K. Wu, a distinct species with winged peduncles which was overlooked in previous studies, is also reported here. We provided detailed descriptions, expanded distributions, habitat and phenological information, conservation status, and taxonomic notes for these five species. An updated key to the genus is also provided.
