Abstract
A new fern species, Polystichum hubeiense Liang Zhang & Li Bing Zhang (Dryopteridaceae), is described and illustrated from limestone cliffs in western Hubei Province, China. Polystichum hubeiense is most similar to P. lanceolatum in having relatively small leaves and pinnae and similar pairs of pinnae per lamina. The new species is distinguished by having overlapping and papery pinnae that are dull adaxially and repand on the margin, while P. lanceolatum has contiguous and leathery pinnae that are lustrous adaxially and dentate and with hard spines on the margin.
