うろこみずごけ (鱗水苔) [Index] [Back] わが国の北海道から本州・四国、それに朝鮮半島や中国、北半球の寒冷地に広く分布しています。湿原周辺などの木陰の湿った場所に生え、高さは１５〜２０センチになります。大形で「おおみずごけ」に似ていて、明るい緑色をしています。茎は直立して群生し、枝葉は広卵状披針形で、先は急に細く尖り、先端が背側に強くそり返ります。中国語では「粗葉泥炭蘚（cu ye ni tan xian）」と呼ばれます。  ミズゴケ科ミズゴケ属の蘚類で、学名は Sphagnum squarrosum。英名は Spiky bog-moss、Spreading-leaved bog moss。  The Spiky bog-moss (Sphagnum squarrosum) belongs to Sphagnaceae (the Bog moss family). It is a bryopsida (moss) that is distributed from Hokkaido to Honshu and Shikoku in Japan, as well as the Korean Peninsula, China, and widely cold regions in the northern hemisphere. It grows in damp, shady places such as around marshlands and grows 15 to 20 cm tall. It is large in shape, similar to "Bog moss" (Sphagnum palustre) and bright green in color. The stems grow erect in clusters, and the branches and leaves are broadly ovate-lanceolate, with sharply pointed tips that curve back dorsally. In Chinese, it is called "粗葉泥炭蘚" (cu ye ni tan xian).  宮城県村田町「浮島の植物群落」にて、2024年08月22日撮影。  Shu Suehiro shu@botanic.jp
