现生蹄盖蕨（ＡｔｈｙｒｉｕｍＲｏｔｈ）为一大属，约有２００种，主要产于世界温带和亚热带的高山林下，我国有１００余种，以西南高山为分布中心，华北和东北地区也有分布，但不产于热带和亚热带平原地区。中国东北及内蒙早白垩世含煤地层产ＡｔｈｙｒｉｕｍｏｒｅｔａｃｅｕｍＣｈｅｎｅｔＭｅｎｇ，Ａ．ｆｕｘｉｎｅｎｓｅＣｈｅｎｅｔＭｅｎｇ，Ａ．ｈｕｌｕｎｉａｎｕｍＣｈｅｎ，ＲｅｎｅｔＤｅｎｇ，Ａ．ｈａｉｌａｅｒｉａｎｕｍＤｅｎｇｅｔＣｈｅｎ和Ａ．ａｓｙｍｍｅｔｒｉｃｕｍ（Ｍｅｎｇ）Ｄｅｎｇ等５种，该地区很可能为蹄盖蕨的起源中心。起源时间可能为早白垩世。该地区早白垩世地处西伯利亚—加拿大植物区系，气候属温暖潮湿的温带或暧温带，蹄盖蕨与其他真蕨植物繁盛于沼泽边缘的林下。
There are about 200 species of Athyrium Roth, which are mainly found in the temperate and subtropical high mountain forests in the world. There are more than 100 species of Athyrium Roth in our country, with the southwestern mountain as the distribution center and also in North China and Northeast China. But not produced in tropical and subtropical plains.

The origin of time may be Early Cretaceous. Early Cretaceous in the area is located in the Siberia - Canada flora, the climate is warm and humid temperate or warm temperate, hooved ferns and other true fern plants prosperous in the marsh edge of the forest.
