[77.] Desert-willow
More properly called “desert catalpa,” this tall shrub or small tree, 6 to 15 feet high, has willow-like leaves, spreading branches, and a short, crooked, black-barked trunk. The violet-scented flowers usually appear from April to August, often after the start of summer rains. They are replaced by long, slender seed pods that remain dangling from the branches for months. Mexicans make from the dried flowers a tea that they believe has considerable medicinal value. Desert-willow is usually found along desert washes below 4,000 feet from west Texas to southern California and northern Mexico. It is frequently cultivated as an ornamental because of its attractive orchid-like flowers.

[78.] Trumpet-bush
A glossy-leafed shrub with golden, trumpet-shaped flowers, the trumpet-bush blooms from May to October on dry, rocky hillsides between elevations of 3,000 and 5,000 feet. It is not common, but occurs from western Texas through southern New Mexico and Arizona southward into tropical America. Trumpet-bush is cultivated as an ornamental in southern parts of the United States and in Mexico. The roots are used medicinally and in making a beverage. Stems and leaves contain small quantities of rubber. The shrubs, which occasionally reach a height of 6 feet, are browsed by bighorn sheep and probably by deer.
