''Rosa arkansana'', the prairie rose or wild prairie rose, is a species of rose native to a large area of central North America, between the Appalachian and Rocky Mountains from Alberta, Manitoba, and Saskatchewan south to New Mexico, Texas and Indiana. There are two varieties: *''Rosa arkansana'' var. ''arkansana'' *''Rosa arkansana'' var. ''suffulta'' (Greene) Cockerell The name ''Rosa arkansana'' comes from the Arkansas River in Colorado. The species' wide distribution and consequent genetic drift has led to an extensive synonymy. The name prairie rose is also sometimes applied to ''Rosa blanda'', also known as the meadow rose or smooth rose, which is also widely spread, but somewhat further to the north. ==Symbolism== Wild prairie rose is the state flower of the U.S. states of Iowa and North Dakota. In Iowa, convention states the species is ''Rosa pratincola'' (currently treated as a synonym of ''Rosa arkansana''). North Dakota, on the other hand, specifies either ''Rosa arkansana'' or ''Rosa blanda''. Alberta's "wild rose" is ''Rosa acicularis''. 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「Rosa arkansana」の詳細全文を読む スポンサード リンク
