キジノオシダ
ヒノキ林の林縁でキジノオシダが見られます。暖地の林内に生えるシダ植物です。胞子をつける葉（胞子葉）とつけない葉（栄養葉）で形が異なっており、写真は栄養葉です。和名は、葉の形をキジの尾羽に見立てたものです。
"Kijinoo-Shida (キジノオシダ)" fern plants are found on the edge of the Japanese cypress woodland. They are a fern plant that grows in the forests in warm climates. There are two types of leaves in shape. One that bears spores, which are called fertile fronds, and the others that don't bear spores, which are called sterile fronds. The one in the photo is a sterile frond. The name comes from the shape of its fronds, which resemble a pheasant’s tail feathers.
