Gutierrezia sarothrae is a sparsely foliated shrub that inhabits deserts and grasslands between 3000 and 6500 feet elevation. This species also is abundant on disturbed areas and is an indicator of overgrazed rangeland. The grayish green stems and leaves have whitish scales. Leaves are narrowly linear and have a few axillary leaves along their margin. Flowers are formed in clusters and appear after abundant rain. Near and west of Sells, AZ, another species, G arizonica, also is present but at lower elevations.
