Mizosida - Mizosida

Japanese: ミゾシダ - みぞしだ

This is a summer-green fern of the Thelypteridaceae family (illustration), commonly found in mountains, fields, and shady roadside areas. Its Japanese name comes from the fact that it is often found near ditches. The rhizome runs long and horizontally, so the leaves often grow in clusters all over the place. The leaves do not grow upright, but can reach a length of 70 cm including the petiole. The petiole is densely hairy and sparsely scaled. The leaf surface, which is deeply pinnately lobed, is also densely hairy and dark green. The veins are simple, sometimes bifurcated, and reach the margins of the lobes, but do not form a meshwork.

Japanese:

山野，路傍の陰地にごく普通のヒメシダ科の夏緑性シダ（イラスト）。和名は溝の傍に多いことに由来する。根茎は長く横走するので，しばしば一面に葉が群生する。葉は直立することはないが，長さは葉柄を含めて70cmに達することがある。葉柄には密に毛をつけ，まばらに鱗片をつける。単羽状深裂の葉面にも，毛が密につき，暗緑色となる。葉脈は単生，まれに二叉（にさ）することがあり，裂片の辺縁に達するが，網目をつくることはない。
