| General Description: | Latah Tule Pea is an herbaceous perennial with erect stems that stand 1-3 dm tall and arise from slender rhizomes. The alternate leaves have 2-4 paired, strap-shaped to oblong leaflets that are 2-15 cm long and a bristle instead of a tendril on the tip. Each leaf has a pair of narrow, leaf-like wings, or stipules at the point of stem attachment. Foliage is glabrous to sparsely short-hairy. 2-3 pink to light blue, pea-like flowers, 10-13 mm long, are borne on ascending stalks in the axils of the upper leaves. The upper petal is reflexed upward and equal in length to the wing petals but longer than the keel petals. The calyx is 6-8 mm long and has 5 pointed lobes. The fruit is a flattened, elongate-elliptic pod that is 3-4 cm long with 7-12 seeds. | ||||||||||
