Hymenoclea monogyra
Asteraceae (Compositae)
A common shrub from the Trans-Pecos west to Southern California, burrobrush grows in sandy washes and streams at low to mid-elevations. It is thicket-forming and broomlike, easily distinguished from other mid-sized desert shrubs by its dense, upright branching and its thread-like yellowish-green leaves that are 1 to3 inches long. It flowers profusely in September to October with small whitish heads in clusters; male and female flowers often occur in the same cluster. The fruits have a single whorl of papery wing. Drought-deciduous and drought tolerant, burrobush grows in full sun and needs well-drained soil. It would be useful for erosion control in a naturalistic desert landscape. It is usually avoided by livestock, and its pollen is said to cause irritation.
