''Astragalus canadensis'' is a common and widespread member of the milkvetch genus in the legume family, known commonly as Canadian milkvetch. The plant is found throughout Canada and the United States in many habitats including wetlands, woodlands, and prairies. It sends out several thin, erect, green stems, bearing leaves that are actually made up of pairs of leaflets, each leaflet up to 3 centimeters in length. It has inflorescences of tubular, greenish-white flowers which yield beanlike fruits within pods that rattle when dry. Like other ''Astragalus'' species, ''A. canadensis'' is somewhat toxic, but it has been used medicinally by Native American groups such as the Blackfoot and Lakota people, particularly the roots. ==External links== *(USDA Plants Profile ) *(Photo Gallery ) *(Native Plants of Texas ) *(Ethnobotany ) 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Astragalus canadensis」の詳細全文を読む スポンサード リンク
