This has flowers resembling the cultivated Sweet Pea, but the whole effect is more airy and graceful. It is a loosely-trailing vine, with slender, angled stems, long, narrow leaflets, eight in number, and three-cleft tendrils. The flowers are about three-quarters of an inch long, brightly yet delicately tinted with shaded pink and violet, and are so lightly poised on the long slender stalks that they look like a row of butterflies about to take flight. This grows on the plateau in the Grand Canyon and all through Arizona in the mountains.

Wild Sweer Pea. Lathyrus graminifolius.
