Seeds: 2 by 8 mm, brown, smooth.
Habitat: Dry, well-drained sandy, gravelly, and rocky soils on upper bajadas and moderate slopes in the lower mountains; rocky areas.
Elevation: Typically 3,000 to 7,500 feet (to 10,000 feet).

Comments: Tea can be made by steeping the twigs in boiling water. The stems of most members of this genus contain ephedrine, which is useful in the treatment of breathing problems.
