This is the same as P. coccinatus Rydb., described from Arizona. Apparently more 
variable, at least in sepal length, than the species, and here distinguished solely by 
the pubescence. Perhaps a form rather than a variety, but it seems to have a differ- 
ent range. 
“Among the junipers in gravelly soil”; doubtless in situations similar to those of 
P. eatoni, but known from altitudes of 810 to 1,650 meters; Upper Sonoran Zone; 
flowering from late April to mid-June. In the Colorado drainage, southwestern Colo- 
rado, southern Utah, and northern Arizona.
