Caudex branches short to elongate. Stems solitary or ± tufted, (2.5–)3–6 dm; base 2–4 mm diam., septate-glandular. Leaves moderately hairy; basal (6–)10–24 cm, leaflet pairs 2–3; terminal leaflet obovate, 2–5 × 1.5–4 cm, teeth double, (5–)8–12(–15) per side, apex obtuse; cauline 1–3, well developed, leaflet pairs 2–3. Inflorescences 10–20(–30)-flowered, leafy, congested clusters terminating branches, 1/10–1/3(–1/2) of stem, narrow, branch angles 5–20°. Pedicels 1–5 mm, predominantly short-hairy, often velutinous, sparsely to moderately septate-glandular. Flowers opening widely; epicalyx bractlets linear to oblanceolate-elliptic, 2–4(–6) × (0.5–)1–1.5 mm; sepals spreading, 4–7(–9) mm, apex obtuse; petals not overlapping, spreading, cream-white, obovate-elliptic, 2–5 × 1.5–3.5 mm, shorter than sepals; filaments 1–2 mm, anthers 0.5–0.8 mm; styles thickened, 1 mm. Achenes reddish, 1.3 mm.
Phenology: Flowering May–Jul.
Habitat: Mountain brush in canyons, pinyon-juniper woodlands
Elevation: 1400–2600 m
Discussion
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.
