Tagarasi (English spelling) Celery-leaved ache

Japanese: タガラシ - たがらし(英語表記)celery-leaved ache
Tagarasi (English spelling) Celery-leaved ache

A biennial plant of the Ranunculaceae (APG classification: Ranunculaceae). The stems are soft and shiny, and grow to 10-50 cm in height. The leaves are simple and deeply 3-lobed. In April and May, it produces sparse racemes and produces many yellow flowers about 1 cm in diameter. The petals are the same size as the sepals and are not very noticeable. The achene is swollen. It is similar to the foxglove (Umanoashigata) and the foxglove (Kekkitsune nobotan), which are also in the Ranunculaceae family, but this species can be easily distinguished by its cylindrical aggregate. It is a weed commonly found in wet marshes, and is widely distributed throughout Japan and the Northern Hemisphere. It is named after its pungent taste, which is caused by the poisonous protoanemonin.

Japanese:

キンポウゲ科(APG分類:キンポウゲ科)の越年草。茎は柔らかく光沢があり、高さ10~50センチメートル。葉は単葉で3深裂する。4~5月、まばらな総状花序をつくり、径約1センチメートルの黄色花を多数開く。花弁は萼片(がくへん)と同じ大きさで、あまり目だたない。痩果(そうか)は膨らむ。同じくキンポウゲ科のキツネノボタン(ウマノアシガタ)やケキツネノボタンに似るが、本種は集合果が円筒状であることから容易に区別できる。水湿地に普通にみられる雑草で、日本全土および北半球に広く分布する。全体に辛味があるのでこの名がある。辛味の成分は有毒のプロトアネモニンである。
