Abstract

Abstract:

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.

Key words: Polystichum, Polystichum mulunense, Guangxi, Karst cave, New species

摘要：

报道了广西石灰岩洞穴植物一新种——木论耳蕨 (Polystichum mulunense XL. Shen & RH. Jiang)，本种形态特征近似广西耳蕨 (Polystichum guangxiense WM. Chu et HG. Zhou) 和凤山耳蕨 (Pfengshanense LB. Zhang et H. He)，不同之处在于本种根状茎的鳞片披针形，边缘被稀疏的细齿；叶片基部略收缩；小羽片长斜方形至斜方形，革质，疏生，以60~70°的角度斜升羽轴。
