Plants (2-)6-15(-25+) cm. Leaves: blades oblanceolate to linear-oblanceolate, glabrous or sparsely to moderately hairy (not strigoso-canescent or sericeous), some (usually most or all) eglandular or sparsely gland-dotted. Heads 1-10(-15) per plant. Peduncles (1-)5-15(-25) cm. Outer phyllaries 6-12, 5-7.5 mm, margins 0-0.2 mm wide, sometimes slightly scarious, abaxial faces ± hairy. Ray florets 10-14; corollas 11-19 mm. Cypselae 3-4 mm; pappi 2.8-3.7 mm. 2n = 28, 56. Flowering May-Jul(-Sep). Roadsides, hillsides, edges of woods; 1600-2700(-3500) m; Colo., Utah, Wyo. Some plants of Hymenoxys acaulis from south-central to northeastern Utah and northwestern Colorado have moderately gland-dotted leaf blades. We interpret them to be intermediates between var. epunctata and var. arizonica. Plants referable to var. epunctata have eglandular or very sparsely gland-dotted blades; those referable to var. arizonica have densely gland-dotted blades.
