【摘要】 报道了赣西南崇义和大余两县的蕨类植物共37科，81属，166种和3变种及其生态分布概况，其中条裂三叉蕨（Tectariaphaeocaulis（Rosens）C．Chr）和光蹄盖蕨（Athyriumotophorum(Miq.)Koidz．）为江西新分布。并对其与九连山、井冈山、庐山和三清山的蕨类植物属、种相似率作了比较分析，发现其属、种相似率都非常相近，且随地域相距逐渐增加，而其相似率逐渐降低。更多还原

【Abstract】 This paper reports 166 species and 3 varieties of Pteridophyta belonging to 81 genera of 37families from Chong yi and Da’ yu and their ecological distribution. Two ferns are discovered forthe first time in Jiangxi: Tectaria phaeocvulis (Rosenst. ) C. Chr. and Athyrium otophorum(Miq. ) Koidz compared the genera and species of Pteridophyta in Chong yi and Da yu with thosein Jiulianshan, Jingganshan, Lushan and Sanqingshan mountains. The pteridophytical similarityrates are much close. The more distance is increasede. The more similarity rates is reduced.更多还原
