Herbs, erect, 1.5–3.5(–4) × 0.5–1 dm, tomentose. Stems: caudex absent; aerial flowering stems erect, stout, solid, not fistulose, arising directly from a taproot, (0.5–)1–2 dm, tomentose. Leaves basal, not in rosettes; petiole 4–10 cm, tomentose to floccose; blade lanceolate to elliptic, (2–)4–12(–15) × 1–3.5 cm, densely white-tomentose abaxially, floccose or glabrous and green adaxially, margins entire, plane. Inflorescences compound-umbellate, 5–15(–20) × 3–10(–12) cm; branches tomentose; bracts 3–6, leaflike at proximal node, 1–4 × 0.5–1.5(–1.8) cm, often scalelike distally. Involucres 1 per node, turbinate to campanulate, 3–5 × 2–4 mm, tomentose; teeth 5–7, erect or slightly spreading, 0.3–0.6 mm. Flowers (2.5–)3–7 mm, including 1–1.5(–2) mm stipelike base; perianth bright yellow, densely pubescent; tepals dimorphic, those of outer whorl lanceolate to elliptic, 2.5–5 × 1.5–2.5 mm, those of inner whorl elliptic to fan-shaped, 4–7 × 2–3.5 mm; stamens exserted, 3–5 mm; filaments pilose proximally. Achenes light brown to brown, 3.5–6 mm, glabrous except for sparsely pubescent beak. 2n = 40.
Phenology: Flowering Jul–Oct.
Habitat: On clayey flats and mounds, mesquite communities, oak and juniper woodlands
Elevation: 400-1000 m
