R. eglanteria of Michigan Flora.

A Eurasian species, locally naturalized as an escape from cultivation on roadsides, fields, railroads, old dunes, shores and river banks, borders of forests. Its very prickly stems are avoided by grazing animals, so that it can dominate the vegetation when well established. First collected in 1880 in Van Buren Co.

The leaflets, stipules, and sepals are all provided with abundant short-stalked glands and the foliage is ± fragrant. Some other species in the genus will rarely have a narrow lobe on a sepal, but such plants differ from the species in the first half of the key in other characters (e.g., R. setigera has mostly trifoliolate leaves and glabrous styles).
