ヒノキ林の林床などでオニ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。葉は硬く光沢があります。似た仲間が多く、雑種も作りやすいため見分けるのが難しい種です。


 

"Oni-Kanawarabi" ferns are growing in the Japanese cypress woodland. They are evergreen ferns in the Dryopteridaceae family. Their fronds are thick and glossy. There are many similar species and they hybridize easily, so it's difficult to identify them.

 ナツミカンの実がなっています。果実は晩秋から黄色く色づきますが、まだ酸味が強いのでこのまま初夏まで待ってから収穫します。たくさん実をつける表年と少ない裏年を交互に繰り返す性質があると言われますが、今年は表年のようです。

A "Natsu-Mikan" tree is now bearing fruits. Their fruit starts to turn yellow in late fall, but it remains too sour at that time, so we wait until early summer to harvest it. The tree has on-years, when it produces a large amount of fruit, and off-years, when production is low. These alternate from year to year. This year appears to be an on-year.
