A biennial plant of the Caryophyllaceae family (APG classification: Caryophyllaceae). The stem grows in a clump and is about 20 cm tall. The leaves are stalkless, opposite, elliptical, about 1.5 cm long, and covered with hairs on both sides. Many flowers are produced in cymes at the end of the stems from April to May. The five petals are about 5 mm long and white, with a shallow two-lobed tip. The fruit protrudes longer than the calyx and has 10 lobes at the end. A naturalized plant native to Europe, it has become a weed in fields and roadsides throughout Japan. It is yellowish green overall, hairy, and has shorter flower stalks than the sepals, so it is distinguished from the Japanese quince, which is also a weed. The Dutch quince was naturalized in Japan more recently, but it has spread to urban areas and is now more commonly seen than the Japanese quince.

Many flowers bloom in cymes at the end of the stems from April to May. The five petals are white and shallowly bisected at the end. Commonly found in fields and roadsides .

ナデシコ科(APG分類:ナデシコ科)の越年草。茎は株立ちとなり高さ約20センチメートル。葉は柄(え)がなく対生し、楕円(だえん)形で長さ約1.5センチメートル、両面とも毛に覆われる。4月から5月にかけて、茎の先の集散花序に多くの花をつける。花弁は5枚、長さ5ミリメートルほどで白色、先は浅く二つに切れ込む。果実は、萼(がく)よりも長く突き出て、先が10裂する。ヨーロッパ原産の帰化植物で、日本全土の畑や道端の雑草となっている。全体が黄色がかった緑色で、毛が多く、花柄が萼片よりも短いので、同じく雑草であるミミナグサと区別する。日本に帰化したのはオランダミミナグサのほうが新しいが、都市部を中心に分布を広げ、いまではミミナグサよりもよくみられるようになった。 [三木栄二 2021年1月21日] [参照項目] |葉には葉柄がなく対生し、両面とも毛に覆われる。4~5月、茎の先の集散花序に多くの花をつける。花弁は5枚で白色、先は浅く2裂する。畑や道端に普通にみられる©Seishohmaru"> オランダミミナグサ 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
