Drymocallis micropetala
Drymocallis 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.

Drymocallis deseretica is common in the Wasatch and western Uintah mountains of northern and central Utah, where it has usually been treated as Potentilla glandulosa var. intermedia (= D. glabrata) or P. glandulosa var. pseudorupestris (= D. pseudorupestris var. saxicola). It differs from both taxa in its more compact inflorescences, predominantly short-hairy pedicels, and sepals that conspicuously enlarge in fruit, which create a distinctive aspect. Comparable plants with shorter, obtuse sepals occur in the Raft River Mountains; their optimal placement remains to be determined. Inclusion of Wyoming in the species range is based on Goodding 1993 (UT) from Bridger Peak, Carbon County. Drymocallis deseretica intergrades with D. glabrata to the north and D. arizonica to the south, with the exact range yet to be determined.
