Double Form Snout Bean is an herbaceous perennial member of the Bean family (Fabaceae). It occurs throughout the state but is most common in the Wiregrass region of southeast Alabama. Double Form Snout Bean grows in dry pine or pine/hardwood woodlands, in sandhills, in old fields, and on roadsides. It is a twining vine up to four feet in length. The stems are green in color and pubescent. The leaves are alternate, trifoliate, and pubescent at least on the lower surface. The leaflets are suborbicular to elliptic in outline with conspicuous netted veins and inconspicuous resin dots. Flowers are produced in racemes from the axils of the mid- to upper leaves. Flowers number from 3-8 per raceme. Flowers are papilionaceous, consisting of a banner or standard petal, two wing petals, and two united keel petals. The corolla is shorter than the calyx and the petals are yellow in color. The fruit is an ovate to oblong pubescent legume with a hooked beak. It contains one or two seeds.—A. Diamond
