Drymocallis glabrata
Drymocallis micropetala
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.

Drymocallis micropetala is poorly known; it combines the aspect and narrow inflorescence of D. convallaria, the small petals of D. glandulosa, and the predominantly short-hairy pedicels of D. deseretica. Plants with equally small petals that occur sporadically throughout the range of D. convallaria are predominantly septate-glandular rather than short-hairy on the petioles and are not included here. As circumscribed here, D. micropetala occurs only in the Wasatch Range of north-central Utah, from Juab to Rich counties; it is possibly of conservation concern.
