Discussion

Of conservation concern.

Variety psilocarpa is apparently restricted to Carbon, Duchesne, Emery, and Wasatch counties in east-central Utah.

L. C. Anderson (1986b) excluded the name Ericameria nauseosa var. glareosa (M. E. Jones) G. L. Nesom & G. I. Baird [as Chrysothamnus nauseosus subsp. glareosus (M. E. Jones) H. M. Hall & Clements], because he had seen no herbarium or field material. Jones’s original description is sketchy; he mentioned its similarity to subsp. leiosperma. S. L. Welsh et al. (1987) noted the uncertain disposition of this taxon. A. Cronquist (1994) recognized C. nauseosus var. glareosus (M. E. Jones) H. M. Hall and placed C. nauseosus var. psilocarpus in synonymy, noting that it was equal to E. nauseosa var. glareosa (M. E. Jones) G. L. Nesom & G. I. Baird. Without more substantial documentation, use of var. psilocarpa is preferred over var. glareosa, which we take to be of uncertain application.
