オオカナワラビ
ヒノキ林の林床にオオカナワラビが見られます。オシダ科の常緑性のシダ植物です。和名のカナワラビ（鉄蕨）は、葉が硬く光沢があることに由来しますが、本種は他のカナワラビの仲間と比べて柔らかい葉をもっています。
"Oo-Kanawarabi" ferns are growing in the Japanese cypress woodland. They are evergreen ferns in the Dryopteridaceae family. The name "Kanawarabi" comes from their thick and glossy fronds. However, the fronds of this species are softer than those of their close relatives.
