The flowers are in axillary sub-umbellate racemes near the ends of the branches; the 5 large yellow petals are glabrous, about 1/2 inch long, with reddish veins, and 10 stamens with large orange anthers..
The slightly curved pods, 3/4 to 1 1/3 inches long, are tipped by a stiff point about 1/8 inch long. They pop open with force when mature, throwing the seeds some distance from the plant. The pinkish brown seeds are pearshaped, deeply wrinkled, and flattened, about l/8 inch long.
