Notes

Abundant on the rocky outcrops, desert shrub communities (Fig. 28), and plateaus surrounding MDRS, this species is well adapted to disturbance in Utah's desert rangelands ( Welsh et al. 1993). Gutierrezia sarothrae was previously reported from the nearby San Rafael Swell as Xanthocephalum sarothrae (Pursh) Shinners ( Harris 1983). Gutierrezia is now segregated into a distinct genus ( Nesom 2006).
