slender, suberect, or diffuse, silky and villous; stipule solitary, linear-lanceolate; leaflets ternate, linear-lanceolate, acute, subpungent; flowers solitary, pedicellate, opposite the leaves; calyx deeply divided, silky, its lobes subequal, subulate, shorter than the corolla; vexillum obovate, acuminate, rather shorter than the broad, falcate, glabrous carina; legume villoso-pilose, twice as long as the calyx, at length turgid. Very similar to L. laxa, but the leaflets are narrower, more lanceolate, and sharper; the pubescence is not silvery but villous, or inclining to pilose, the calyx is more deeply divided and the lobes much narrower; and the corolla is larger and more exserted. The three Ecklonian species here united, differ chiefly in the more or less abundant villosity; the character of the pubescence is the same in all. Stems 6–12 inches long. Leaflets 1/2 inch long, not a line wide.
