| Abstract | Polystichum ensiforme, a new polystichoid fern species from Guangxi Zhuang Autonomous Region, China, is described and illustrated. Morphologically, the new species most closely resembles P. basipinnatum but differs in having a generally simple lamina, scattered sori, and leathery lamina texture. Phylogenetic analysis placed it as an isolated clade within P. sect. Cyrtomiopsis. A key to the species of P. sect. Cyrtomiopsis is also provided. |
