凤尾蕨属，学名Pteris L.，为凤尾蕨科多年生常绿草本。株高30～70厘米，根状茎直立，顶端具钻形叶片，叶簇生，分为不育叶和孢子叶两种类型，叶柄细，具三棱，黄褐色，叶椭圆至卵形，长20～45厘米，宽15～25厘米，1回羽状复叶，羽片常4～6对，仅基部有一队叶柄。羽片条形，宽3～7厘米，顶端尖，有细锯齿，孢子叶较高，全缘。孢子囊群沿叶边呈线形排列。
从孢子形态上看，栗蕨属与凤尾蕨属有很大差异，将其放在一个科中不合适。
The spore morphology of Histiopteris and pteris is very differential, put genus Histiopteris in family Pteridaceae is not suitable, according to the feature of spore morphology.
凤尾蕨属植物孢子的形态稳定， 种间差异明显， 但孢子形态特征与孢子体的形态特征是不相关的。
The spore morphology of Pteris is stable, and the difference between species is distinct , but the features of spore and sporophyte are not related.
主要属为凤尾蕨属、线蕨属、狗脊蕨属、卷柏属和铁角蕨属，其中以凤尾蕨属和狗脊蕨属分布相对集中。
The main genera are Pteris L., Colysis Presl, Woodwardia Sm., Selaginella Spring and Asplenium L., among which Pteris L. and Woodwardia Sm. have relatively intensive distribution.
