安徽省蕨类植物分布新记录(Ⅰ)

New records of pteridophytes distributed in Anhui Province(Ⅰ)

安徽省的植被区跨越亚热带常绿阔叶林区域与暖温带落叶阔叶林区域,分布的蕨类植物（含石松类）约有237种（含种下分类单位）,而与其毗邻的浙江省和江西省分布的蕨类植物均达430种以上[1],蕨类植物的丰富程度明显优于安徽省,这-现象与浙赣两省地处亚热带常绿阔叶林区域有一定关系,蕨类植物特别丰富是热带、亚热带植物区系的特点[2].

By means of field investigation,specimen identification,and related literatures,five species and one variety belonging to six genera in five families of pteridophytes were identified as new records in Anhui Province, viz.Phlegmariurus cryptomerianus( Maxim.) Ching ex H. S. Kung et Li Bing Zhang,Osmunda claytoniana Linn.,Thelypteris palustris var. pubescens( G. Lawson) Fernald,Cyclosorus dentatus( Forssk.) Ching,Athyrium imbricatum Christ,and Hypodematium hirsutum( D. Don) Ching. Voucher specimens are deposited in Shanghai Chenshan Herbarium( CSH).
