Distribution patterns and morphological differentiation of leaves of some cryospheric ferns of Polystichum, Dryopteris and Athyrium were surveyed in Hokkaido and Shinshu. The summer green fern leaves of Dryopteris coreno-montana and Thelypteris phegopteris showed no cline of size and shape along latitudinal distribution zones. Semi-evergreen leaves of Polystichum tripteron showed a morphological cline in shape-complexity along altitudinal and latitudinal zones. Even in a same size of leaves of Polystichum tripteron the leaf-shape complexity decreases in northern regions and highland of Japan. No difference was found in leaf-shape and leaf-size in Dryoteris coreano-montana from relict populations of Shinshu, Hokkaido and Sakhalin. Athyrium yokoscense and A. niponicum showed no clear differentiation, however they have wide range of distributions in Japan. These species has large variation in leaf-shape and leaf-size within a plant, which might regulate leaf number and phenology for the survival of wide range of habitats and distribution area.

对北海道和信州的几种寒地蕨类植物耳蕨属、鳞毛蕨属和冰蕨属的分布格局和叶的形态分化进行了调查。在沿着纬度分布带上，核鳞毛蕨和糙叶金星蕨的夏季绿色蕨类叶片在大小和形状上没有明显的梯度。雷公藤耳蕨的半常绿叶在形态复杂性上沿着纬度和海拔方向表现出明显的渐变趋势。在北方地区和日本高原，即使在相同大小的叶中，叶的形状复杂性也降低。来自信州、北海道和库页岛的朝鲜鳞毛蕨在叶形和叶大小上没有差异。A.yokoscense和A.在日本的分布范围很广，但在分化上没有明显的差异。这些物种在同一植株内的叶形和叶大小差异很大，可能是它们在广泛的生境和分布区中生存所必需的叶数和物候的调节因子。
