Asteraceae (Compositae)

Shrubby poreleaf is frequent in desert arroyos and on limestone banks in the Trans-Pecos from El Paso and Culberson, through Brewster and Val Verde, into New Mexico and Mexico, forming pure stands year round. It is a western shrubby-based perennial with many erect, broom-like stems and a few linear, firm and thick, thread-like leaves. It somewhat resembles Ephedra. The stems start out green and turn brown with age. This member of the Asteraceae family has only disc-shaped flowers, lacking ray flowers. Shrubby poreleaf is said to be an unpleasant smelling plant. In Mexico it is used as a remedy for rheumatism, fever and intestinal problems.
