Perennials, 30–60+ cm; taprooted (caudices relatively thick, weakly ascending or erect), sometimes stoloniferous. Stems 1, densely lanate-tomentose proximally, floccose-tomentose to glabrescent distally. Basal leaves (and proximal cauline) petiolate; blades lanceolate to narrowly ovate or elliptic, 40–120+ × 20–50+ mm, bases tapering, sometimes oblique, margins subentire, crenate, or serrate-dentate. Cauline leaves gradually reduced (± petiolate or sessile, weakly clasping; dentate to pinnately lobed). Heads 10–30+ in open, corymbiform arrays (more in robust individuals). Peduncles bracteate, sparsely to densely tomentose. Calyculi inconspicuous. Phyllaries 13 or 21, light green, 5–8 mm, usually glabrous (sometimes hairy proximally). Ray-florets 10 or 13; corolla laminae 6–8+ mm. Disc-florets 50–60+; corolla-tubes 3.5–4 mm, limbs 3–3.5 mm. Cypselae 1–1.5 mm, hispid; pappi 5–7 mm. 2n = 46.
Phenology: Flowering (Mar–)May–early Jun.
Habitat: Open meadows, roadways, sandy or shallow soils overlying granitic outcrops
Elevation: 0–500 m
