 ヒノキ林の林床でキジノオシダを見つけました。暖地に生えるシダ植物です。先日紹介した近縁のオオキジノオととても良く似ています（オオキジノオの記事はこちら）。


葉の先端付近の羽片の軸にくっついている部分を見ることで両者を見分けることができます。下の写真のようにキジノオシダは羽片の上側が広く軸につくのに対し、オオキジノオは羽片の下側が広く軸につきます。


I found a fern called "Kijinoo-Shida (キジノオシダ)" on the Japanese cypress woodland floor. They are a fern plant that grows in warm climate. They are similar to a close-related fern called "Oo-Kijinoo (オオキジノオ)", which I posted the other day (Click here to read the article).
You can distinguish between the two by looking at where the pinna connects to the axis. The upper part of the pinna of "Kijinoo-Shida (キジノオシダ)" is wider at this point. In the case of "Oo-Kijinoo (オオキジノオ)" it is the lower part of the pinna that is wider where it connects to the axis.
