Herbs, erect, perennial, occasion-ally flowering first year, 1-10(-15) dm, glabrous, usually glaucous, grayish. Stems: caudex compact; aerial flowering stems erect, solid or hollow and fistulose, (0.2-)2-5 dm, glabrous, usually glaucous, occasionally hirsute proximally. Leaves basal; petiole 2-6 cm, hirsute; blade oblong-ovate to oblong or rounded to reniform, (0.5-)1-2.5(-3) × (0.5-)1-2(-2.5) cm, short-hirsute and grayish or greenish on both surfaces, sometimes less so or glabrous and green adaxially, margins occasionally undulate. Inflorescences cymose, open, spreading to erect, 5-70 × 5-50 cm; branches occasionally fistulose, glabrous, usually glaucous; bracts 3, scalelike, 1-2.5(-5) × 1-2.5 mm. Peduncles erect, straight, filiform to capillary, 0.5-2(-3.5) cm, glabrous. Involucres turbinate, 1-1.5 × 1-1.8 mm, glabrous; teeth 5, erect, 0.4-0.6 mm. Flowers (1-)2-3(-4) mm; perianth yellow with greenish or reddish midribs, densely hirsute with coarse curved hairs; tepals monomorphic, narrowly ovoid to ovate; stamens exserted, 1.3-2.5 mm; filaments glabrous or sparsely pubescent proximally. Achenes light brown to brown, lenticular to 3-gonous, 2-2.5 mm, glabrous. 2n = 32. Herbs, erect, perennial, occasion-ally flowering first year, 1-10(-15) dm, glabrous, usually glaucous, grayish.
