A new section of the fern genus Polystichum Roth ──Sect. Neopolystichum Ching

ZHANG Li Bing * * KUNG Hsian Shiu (Chengdu Institute of Biology,the Chinese Academy of Sciences, Chengdu 610041)  
A new section (Sect. Neopolystichu Ching) of Polystichum Roth is described. The lanceolate microscales on the lower surfaces of pinnules make this section very different from Sect. Metapolystichum Tagawa(emend. Zhang Kung, 1996). The new section is taxonomically treated with seven species recorded in it. It is considered that P. kiusiuense Tagawa is a synonym of P. grandifrons C. Chr. and it is very possible that P. biaristatum(Bl.) Moore is not distributed in the Himalayas, Indo China, Myanmar and Yunnan.
