The only kind, a fine plant, well worth cultivation; smooth and branching, about two feet tall, with handsome, bluish-green leaves, with a "bloom," the root-leaves with long, purplish leaf-stalks and sometimes nine inches long; the flowers half an inch across, with a lilac-tinged calyx and white petals, prettily toothed, forming a pretty, rather flat-topped cluster. The pods are very slender, nearly straight, one or two inches long. This grows among rocks, in protected situations, and is not common. Only a few, separate flowers are given in the picture, as the plant I found, near the Desert Laboratory at Tucson, was almost out of bloom.
There are a good many kinds of Lesquerella, all American; low plants, more or less hairy or scurfy; flowers mostly yellow, in clusters; petals without claws; pods roundish, more or less inflated, and giving the common name, Bladder-pod, also used for Isomeris arborea.
