裏道の小川のそばでクリハランを見つけました。名前の通り、クリの葉に似た葉をもつシダ植物です。


切れ込みのない葉はシダらしくありませんが、裏面には円形の胞子のう群がついており、シダ植物であることがわかります。


I found this fern called "Kuriharan (クリハラン)" by a stream on the back road. "Kuri (クリ)" in its name means "chestnuts". As the name suggests, their leaves resemble chestnuts' leaves. You may think the leaves without laciniae don't look like fern plants, but you will understand that the plant is fern by seeing the round-shaped sori on the back of the leaves.
