Wildflowers of Southern Arizona
Small Wild Bean.
Pea (Fabaceae) family.
The flower stalks emerge from the leaf axils and have 1 or 2 pea-like flowers. The individual flowers have a broad, upright, somewhat cupped, fan-shaped banner petal and a tightly coiled, white and green keel above 2 large, paddle-shaped wing petals. The flowers are followed by hairy, green drying to brown, linear, straight, flattened bean pods with an upcurved tip. The leaves are dark green, minutely sparsely hairy, alternate, and trifoliate with 3 lance-shaped leaflets that are somewhat curved like a sickle. The stems are slender, erect to twining, hairy, and green to brownish in color. The plants grow from a plump, rounded, underground tuber.
