キッコウハグマ
ヒノキ林でキッコウハグマが果実をつけています。果実にはがくが変化した羽毛状の冠毛があります。花は秋に咲きますが、蕾状のまま花が開かない閉鎖花をつけることが多く、キャンパス内では花びらが開いた状態の開放花を見たことがありません。
The "Kikkou-Haguma (キッコウハグマ)" plants are bearing fruits in the Japanese cypress woodland. Their fruits have plumy crests on its top, which are transformed from calyxes. They bloom in fall, but in most cases, they bear cleistogamous flowers that don't open their petals. I have never seen their chasmogamous flowers on campus that open their petals.
