土生,中型植物。根状茎短粗,直立或斜升,少有横卧,被鳞片;鳞片狭披针形。叶簇生,多数一型,少数二型。叶柄基部密被鳞片,鳞片形态各样,卵形、卵状披针形至狭披针形,顶端渐尖,边缘全缘或有齿,棕色、栗色或几为黑色,筛孔狭长而不透明。叶片形态亦多样,披针形、倒披针形、椭圆形、三角状卵形至五角形,一至四回羽状。侧生羽片多对。小羽片为下先出,末回小羽片或裂片的基部上侧呈耳状突起,齿尖无芒。叶脉分离,小脉单一或分叉,不达叶边。叶质地草质至革质,叶面通常无毛,叶背及叶轴、羽轴常被相当多的狭披针形、钻形或泡状鳞片,或被纤维状鳞毛;羽轴、小羽轴及主脉下面圆形,上面有纵沟。孢子囊群圆形,背生或有的顶生于小脉上;有囊群盖或偶无盖;囊群盖圆肾形,膜质或纸质,以深缺刻着生,全缘或罕有睫毛,宿存或早落;孢子囊近球形,有长柄,环带由14-20个增厚细胞组成。孢子椭圆形,周壁具褶皱,常形成片状或瘤状突起。染色体基数x=41。本属约有230余种,广布于世界各地,以亚洲大陆(特别是中国、喜马拉雅地区、日本、朝鲜)为分布中心,达到了最大的发展。中国现知有127种,为中国蕨类植物中大属之一。云南有83种,占国产种类的2/3。本属可分为3个亚属:奇羽亚属 (Pycnopteris)、平鳞亚属 (Dryopteris);泡鳞亚属 (Erythrovariae)。其中:奇羽亚属和泡鳞亚属主要分布于东亚热带、亚热带,而平鳞亚属则主要分布中国 一 喜马拉雅亚区的亚高山、高山带。本属不仅为鳞毛蕨科的主干,而且似为三叉蕨科的祖先类型,它和该科的某些具有分离叶脉的属(如肋毛蕨属 Ctenitis, 轴脉蕨属 Ctenitopsis)在形体上经常相同,但叶干后不变褐棕色,而为淡绿色,小羽轴上面不隆起,也不被棕色腊肠形的粗毛,而为凹陷成一纵沟,并且光滑无毛,囊群盖较大,往往为革质或角质,故易区别。Holttum (在 British Fern Gazette 9: part. 6. 208, 1965) 说“鳞毛蕨属与耳蕨属的分野在中国可能消失了”,这是没有根据的。这两个都是很自然的属,不存在中间类型。

本属是自然的分类群,约有230余种,广布于世界各地,以亚洲大陆(特别是中国及喜马拉雅地区其他国家、日本、朝鲜)为分布中心,达到了最大的发展;中国现知有127种,为中国蕨类蕨物中大属之一。
本属不仅为鳞毛蕨科的主干,而且似为三叉蕨科的祖先类型,它和该科的某些具有分离叶脉的属(如肋毛蕨属 Ctenitis,轴脉蕨属 Ctenitopsis)在形体上经常相同,但叶干后不变褐棕色,而为淡绿色,小羽轴上面不隆起,也不被棕色腊肠形的粗毛,而为凹陷成一纵沟,并且光滑无毛,囊群盖较大,往往为革质或角质,故易区别。Holttum(在 British Fern Gazette 9: part. 6. 208. 1965)说“鳞毛蕨属与耳蕨属的分野在中国可能消失了”,这是没有根据的。这两个都是很自然的属,不存在中间类型。
本属可分为3个亚属:奇羽亚属(Subgen. Pycnopteris)、平鳞亚属(Subgen. Dry-opteris);泡鳞亚属(Subgen. Erythrovariae)。
* 秦仁昌教授是中国蕨类植物学的奠基者,也是最早系统研究亚洲鳞毛蕨属的学者之一。早在1938年他就发表了《中国与印度及其邻邦产鳞毛蕨属(Dryopteris)之正误研究》(Bull. Fan. Mem. Inst. Biol. Bot. 8: 364-507. 1938),其中记载中国鳞毛蕨属植物87种11变种。60年代以来他又与裘佩熹、刘正宇、张朝芳等人在刊物和地方植物志中发表了近200个新种,并编制了本属的检索表。我们在编写本志时曾参考了他的手稿。限于当时的条件,他发表新种时所依据的标本甚少,往往只有一份。现据较多的标本,对他发表的新种有所归并。——编著者
