Polystichum mulunense XL. Shen & RH. Jiang, a new species from karst caves in Guangxi, China, is described and illustrated. This new species is morphologically similar to Polystichum guangxiense and Pfengshanense, but can be easily distinguished from the latter by rhizome scales lanceolate, margins sparsely serrulate and pinnules coriaceous, attached at ca. 60-75 degree angles to rachis and rhomboidal to trapeziform.
