Plants (15–)30–60+ cm. Stems proximally piloso-hirsute (hairs 1.5–5+ mm), sometimes stellate-pubescent as well, distally stellate-pubescent, sometimes stipitate-glandular, rarely piloso-hirsute (hairs 1–2+ mm). Leaves: basal 0(–3), cauline 6–24+; blades elliptic or oblanceolate to spatulate or lanceolate, (20–)35–80(–120+) × (10–)20–35(–50+) mm, lengths 2–6+ times widths, bases cuneate to rounded-truncate, margins usually entire, sometimes denticulate, apices rounded to obtuse, faces hirtellous to piloso-hirsute (hairs 0.5–1+ mm). Heads (5–)10–25(–50+) in corymbiform to paniculiform arrays. Peduncles stellate-pubescent and stipitate-glandular (hairs 0.3–0.6+ mm). Calyculi: bractlets 12–15+. Involucres campanulate, 7–9 mm. Phyllaries 13–21+, apices ± acuminate, abaxial faces stellate-pubescent and stipitate-glandular, rarely, if ever, piloso-hirsute. Florets (30–)40–60+; corollas yellow, 9–11 mm. Cypselae columnar, 2.5–3 mm; pappi of 30–40+, stramineous bristles in ± 2 series, 6–7 mm.
"Stems mostly solitary from a short, simple caudex or crown, 2–15 dm, setose at least near the base with spreading hairs seldom as much as 5 mm, becoming stellate and long-stipitate-glandular upward, densely so in the infl; lvs setose on both sides, more densely so on the petiole and along the midrib beneath; basal and often also the lowermost cauline lvs ordinarily deciduous, the lower lvs broadly oblanceolate to elliptic, 5–20 cm (including the usually short petiole) × 1–4.5 cm, the others progressivelyreduced upward, soon becoming sessile, so that the upper part of the stem does not appear to be very leafy; infl open-corymbiform (especially in smaller plants) to more often elongate and cylindric; invol 6–9 mm, hispid with blackish, mostly gland-tipped hairs, especially toward the also stellate-hairy base; fls 40–100; achenes 2–3 mm, truncate, only very obscurely if at all narrowed upward; 2n=18. Open ground and dry woods; especially in sandy soil; N.S. and Que. to Minn., s. to Va., Ky., Mo., and in the mts. to n. Ga. July–Sept."
