Notes

This species, collected on the plateau west of MDRS, was not recorded in the previous floristic survey of the nearby San Rafael Swell Harris (1983) but there is a record of this species occurring in the Glen Canyon Recreational Area to the south ( Hill and Ayers 2009). A shorter form with fewer heads is sometimes recognized as H. cooperi var. canescens (D.C. Eaton) K. F. Parker; however Welsh et al. (1993) did not recognize varieties in Utah, and Bierner (2006) did not recognize varieties in this species whatsoever.
