オオアブラギリ
オオアブラギリの冬芽と果実が見られます。トウダイグサ科の落葉高木です。中国原産で、種子から油を取るために栽培されていたものが野生化しています。近縁のアブラギリの果実の先端が丸いのに対し、先端がとがっているのが特徴です。

You can find the winter buds and the fruits of the "Oo-Aburagiri" tree. It is a deciduous tree in the Euphorbiaceae family. They originally come from China and were once cultivated for their oil and later spread into the wild. While the fruit of their close relatives, called "Aburagiri," has a rounded tip, the fruit of this species has a pointed tip.
