ハナイカダ
ハナイカダが咲いています。山地に見られる落葉低木で、葉の真ん中に花をつけるというユニークな特徴をもっています。雌花だけをつける木と雄花だけをつける木にわかれている雌雄異株です。雌花はふつう１つだけつき、雄花は数個つきます。写真は雄花です。
"Hana-Ikada (ハナイカダ)" trees are in bloom. They are deciduous shrubs that grow in mountains. They have a unique characteristic that their flowers bloom in the center of their leaves. "Hana-Ikada" trees are dioecious. Some trees bloom only female flowers and the others bloom only male flowers. The female trees normally have one female flower on a leaf and the male trees have a few male flowers on a leaf. The flowers in the photo are male flowers.
