摘要:

描述了耳蕨属一新组——新生耳蕨组Sect.Neopolystichum Ching。小羽片背面具披针形小鳞片
使得新生耳蕨组显著区别于后生耳蕨组Sect.Metapolystichum Tagawa(emend.Zhang&Kung,1996)。
本文对新生耳蕨组进行了分类学研究,共记载本组植物7种,并给出了各种植物的地理分布。认为九州
耳蕨P.kiusiuense Tagawa是大叶耳蕨P.grandifrons C. Chr.的一异名,二尖耳蕨P.biaristatum
(Bl.)Moore极有可能并不分布于喜马拉雅、中南半岛、缅甸和云南。

Abstract:

 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. biarista-
tum (B1.) Moore is not distributed in the Himalayas, Indo-China, Myanmar and Yunnan.

Key words: Polystichum, Sect. Neopolystichum, New section
