A very handsome, thrifty-looking plant, about two feet high, the smooth, bright green foliage contrasting finely with the clusters of clear yellow flowers, each about three-quarters of an inch long. The erect, straight pods, two or three inches long, are silky and also the calyxes and buds. This thrives in the mountains, up to an altitude of nine thousand feet, in somewhat moist spots, and its fresh coloring is most attractive. The foliage seems to me to be especially handsome in northern Arizona, but these plants are also beautiful in the Utah canyons. The flowers are scentless and last a long time in water. T. Californica has silvery, silky foliage and is common in California, in damp ground in the hills.

There are many kinds of Parosela, of western North America, Mexico, and the Andes, no one sort common; generally shrubs; leaves almost always compound; leaflets odd in number, small, toothless, with minute stipules, often with glandular dots; flowers small, in terminal clusters; calyx with nearly equal, long, occasionally feathery teeth; corolla with wings and keel longer than the standard, their claws adhering to the lower part of the stamen-tube, but the claw of the small, heart-shaped standard free; stamens nine or ten, filaments united, anthers alike; ovary with a short stalk, or none, style awl-shaped; pod small, membranous, included in the calyx, usually with one seed. P. spinbsa, the Smoke Tree, or Ghost Tree, of western Arizona, is almost leafless, with grayish or whitish branches.
