テリハノイバラ
テリハノイバラの概要
テリハノイバラはバラ科の落葉蔓性低木。原産地は東アジアのチベット高原で、日本では本州から四国、九州まで、国外では朝鮮半島から中国まで分布しています。海岸の砂地から河原、野原、林縁、山地の岩場まで日当たりと水はけの良いところに自生。花言葉は「素朴な愛」です。
テリハノイバラの枝
テリハノイバラの枝は主枝が野茨のように直立せず、四方八方に這い広がるので「這茨」とも呼ばれます。伸びても太くならず、樹皮も無毛で滑らかですが、大きくて鋭い逆さ向きの棘が疎生するため要注意。主枝からは多くの側枝が真っ直ぐ立ち上がり、その先端で花を咲かせます。
テリハノイバラの葉
テリハノイバラの和名は「葉に光沢のある野茨」という意味。野茨の葉には光沢がないからです。葉は羽状で互生。葉序は頂小葉と３対前後の側小葉で形と大きさが揃います。小葉は無毛の楕円形で縁に細かい鋸歯が入り、表面が濃緑色、裏面が淡緑色。托葉は葉柄と合着しています。
テリハノイバラの花
テリハノイバラの花は野茨に似た白色の５〜６弁花です。雌しべは花柱が花床から突出し、柱頭に白毛が密生。その周りを多数の雄しべが囲みます。野茨より咲き始めが一カ月ほど遅く、花着きも疎ら。一方、花冠が一回り大きく、控えめながら甘く香り、咲き終わりが遅くなります。
テリハノイバラの実
テリハノイバラの花後は萼筒が肥大して丸い偽果を形成。赤色に熟して甘く香ります。偽果は野茨と同じくマルチフロリンやクエルセチンなどのフラボノイド配糖体を含有。完熟前に天日に干し、便秘の解消や利尿、浮腫などに用いられます。煎液は外用により腫れ物や挫創の改善に。Memorial Rose
