Discussion | Varieties 3 (3 in the flora). Drymocallis pseudorupestris occurs from Alberta and Washington to California and Utah, mostly in montane habitats; it is the species most often associated with rocky habitats, including talus slopes, for which its relatively elongate caudex branches are an obvious adaptation. Vestiture is dominated by abundant septate glands on stems and in the inflorescences. Except for var. pseudorupestris, which occurs only in the northeastern part of the species range, plants are relatively short, usually less than 2.5 dm. Three intergrading varieties accommodate the extremes at the northeastern and southern ends of the range. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Drymocallis glabrata is the common member of the genus in central Idaho and adjacent parts of neighboring states, characterized by acute, glabrate leaves, leafy, widely branched inflorescences, relatively long pedicels with slender, septate glands, linear-oblanceolate epicalyx bractlets, and relatively large, bright yellow petals. Plants from northern Idaho, at the lower elevational extreme, tend to be hairier than those elsewhere in the species range. The species enters Utah in Cache and Weber counties; most other Utah populations placed by S. L. Welsh et al. (1993) in this taxon (as Potentilla glandulosa var. intermedia) are treated here as D. deseretica. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
