''Cardamine pensylvanica'' is a species of ''Cardamine'' known by the common name Pennsylvania bittercress. It is native to most of Canada and the United States from coast to coast. It is generally found in moist to wet areas, such as the mud on riverbanks. It is a biennial herb producing one or more erect or leaning, branching stems which are purple to green in color and grow tall. The leaves are hairless and divided into several rounded to oval lobes, each of which has one or two lobes, with the exception of the large terminal leaflet at the tip, which generally has three. Most of the leaves are located along the stem and there is no basal rosette. The inflorescence comprises many flowers, each with four white petals a few millimeters long. The fruit is a slender silique long. ==External links== *(Jepson Manual Treatment ) *(USDA Plants Profile ) *(Missouri Plants ) *(Illinois Wildflowers ) *(Photo gallery ) 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「Cardamine pensylvanica」の詳細全文を読む スポンサード リンク
