This very leafy, much branched Cinquefoil grows from six inches to four feet high, and, on account of its rapid and persistent growth, it has roused the ire of farmers, particularly in the New England States, where it has been severely condemned as a most troublesome weed. The tough, shreddy barked stem is stained with brown. The leaf has from five to seven narrow, oblong, silky-surfaced and crowded leaflets, and they approach nearer to the shape of the fingers than those of any of the other Cinquefoils. They are thick-textured, and the toothless edges are slightly curled under. They are whiter on the under side. The large, five - petalled, bright yellow flowers are densely grouped on slender stems, in terminal, leafy flat-topped clusters, or sometimes they are solitary. The numerous stamens are tipped with darker coloured anthers. This plant is found from June to September in swamps or moist, rocky places, in Labrador and Greenland, to Alaska, south to New Jersey, Illinois, Minnesota, and in the Rocky Mountains to Arizona, where it prospers in dry, sandy soils, and in the Sierra Neva-das to California. Also in northern Europe and Asia.
