Characteristics

Plants 30–120 cm; caudices branching, sometimes with elongate rhizomes forming new rosettes. Stems 1–10+ , erect, glabrous, sometimes sparsely hairy in arrays; usually with fascicles of small leaves in axils of distal leaves. Leaves: basal and proximal cauline tapering gradually to winged petioles, blades oblanceolate to ovate, 100–300 × 20–70 mm, usually multiple lateral nerves pronounced, margins sharply serrate, ciliate, faces glabrous; mid to distal cauline sessile, blades linear-lanceolate, 30–50 × 8–11 mm, reduced distally, margins entire or finely serrate. Heads 60–450 , secund, in paniculiform arrays, openly secund-pyramidal with proximal branches spreading-recurved, or as broad as long with proximal branches widely ascending, recurved (elm-tree shaped). Peduncles 1.5–6 mm, glabrous or sparsely strigillose; bracteoles 0–2, linear. Involucres narrowly campanulate, 3–4 mm. Phyllaries in 3–4 series, strongly unequal, outer ovate, acute, inner lanceolate, obtuse. Ray florets 7–12; laminae 2–2.5 × 0.2–0.5 mm. Disc florets 8–15; corollas 2.5–3 mm, lobes 0.5–0.8 mm. Cypselae 0.9–1.5 mm, sparsely strigose; pappi 2.5–3.5 mm. 2n = 18.
More
Plants 3–12 dm from a stout, branched caudex or short rhizome, commonly with ± deep-seated creeping rhizomes as well, essentially glabrous, or sometimes ± short-hirsute on the lvs or in the infl; lvs basally disposed, the larger ones 15–40 × 2–7.5 cm, with rather narrowly elliptic-acuminate, ± serrate blade tapering to the long petiole; infl dense, mostly about as broad as long, with recurved-secund branches; invol 3–5 mm; rays 7–12, minute; disk fls 9–14; receptacle with some slender, chaffy, phyllary-like bracts near the margin internal to the rays; achenes short-hairy; 2n=18. Dry, open places and open woods, especially in sandy soil; N.S. and N.B. to Minn., s. to Va., Tenn., ne. Miss., Mo., and in the mts. to n. Ga. and n. Ala.
