| 摘 要： | 高山耳蕨组的成员是中国西部、印度北部和喜马拉雅山区常见的蕨类。其成员为夏绿植物，叶片
薄而柔弱。秋季叶片枯萎后叶柄基部宿存在地面形成一个丛堆以保护幼芽，这显然是对高山严峻环境
的适应。作为高山地带特有类型，1972年日本蕨类学家Sigeru Daigobo将它们作为耳蕨属下的一个组
——高山耳蕨组Sect．Lasiopolystichum Daigobo，这是合理的。Daigobo建立此组时只包含3个种，经过
对中国大量标本及有关文献的研究，现知在中国约有30种应归人此组，其中有3新种:红鳞耳蕨P．ru-
fopaleaceum，石生耳蕨P.saxicola，康定耳蕨P．kangdingense；2新变种．裂叶耳蕨P．sinense var．loba-
tum，条裂耳蕨P．mollissimum Var．laciniatum;1新组合，钝裂耳蕨P．integrilobum(Sorolepidium)。据羽片背面的小鳞片类型可将高山耳蕨组划分为2个系:穆坪系Ser．Moupinensia和中华系Ser．Sinensia。

| Abstract: | The members of Polystichum Roth sect. Lasiopolystichum Daigobo are familiar
ferns in the alpine area of W. China, N. India and the Himalayas. They are deciduous with
thin, weak leaves; their persistent base of petioles forms a clumb hiding and protecting buds
from the frost in winter. This may be an adaptation to severe alpine environments. As an en-
demic and natural group, the treatment of it by S. Daigobo(1972) as an independent sec-
tion, Polystichum sect. Lasiopolystichum is reasonable. On the basis of examination of the
specimens of mainland China, 30 species are recognized under this section although S.
Daigobo(1972) established this section with only three species included. Based on the mi-
croseales on the lower surface of pinnae, the section is divided into 2 series: Ser. Moupinen-
sia and Ser. Sinensia. Moreover, three new species, two new varieties and a new combina-
tion are reported: P. rufopaleaceum, P. saxicola, P. kangdingense, P. sinese var. lo-batum , P. mollissium var. laciniatum , and P. integrilobum . |
