The bluish purple flowers of this weak, angular-stemmed, climbing or trailing perennial vine are profusely massed along the borders of thickets and in dry soils during June, July and August, from Newfoundland to New Jersey, and west to Kentucky, Iowa, and Minnesota. The compound leaf has from eighteen to twenty-four small, narrow, lance-shaped leaflets, alternated along opposite sides of a slender stem which terminates in a tendril. The downy, thin-textured leaflets are acutely pointed and bristle-tipped. The main stalk is grooved, and grows from two to four feet in length. The small flowers resemble those of a bean, and are closely crowded along one side of a long curve-ing spike growing from the angles of the leaves. They are reflexed on the stem - that is, they are abruptly bent or turned downward and are not erect, like, for instance, the florets of a freshly opened Clover.
