地中海沿岸からイランにかけてが原産です。いまではわが国をはじめ、南北アメリカにも帰化しています。日当たりの良い草地や道ばたに生え、高さは1メートルほどになります。茎は直立して、よく分枝します。葉は数回の羽状複葉で、小片は糸状になります。6月から7月ごろ、茎頂に複散形花序をだし、小さな白色の5弁花をいっぱい咲かせます。果実は楕円形の分果です。この果実が生薬の「アンミ実」で、鎮痙作用や利尿作用があり、喘息や気管支炎、腎結石に用いられます。ヨーロッパでは昔、この花序の枝を爪楊枝に利用したそうです。

The leaves are several times pinnate compound, and the leaflets are thread-like.
