Treatment appears in FNA Volume 21. Treatment on page 432. Mentioned on page 427.

Perennials, 30–130 cm. Stems 1–3 (–10), unbranched or sparingly branched distally, weakly to moderately winged, glabrous proximally, glabrous or sparsely hairy distally. Leaves glabrous or sparsely hairy; basal blades oblanceolate to oblongelliptic, entire; proximal and mid-blades lanceolate to oblongelliptic, entire; distal blades linear to lanceolate, entire. Heads 1–20 per plant, borne singly or in paniculiform arrays. Peduncles (6–) 10–30 cm, sparsely to moderately hairy. Involucres hemispheric to globoid, 12–20 × (14–) 17–22 (–25) mm. Phyllaries (connate proximally) moderately to densely hairy. Ray-florets 14–20, pistillate, fertile; corollas yellow, 13–25 × 5–10 (–12) mm. Disc-florets 250–500 (–800+); corollas yellow proximally, yellow to brown to purple distally, 3–4.4 (–4.8) mm, lobes 5. Cypselae 1.8–2.4 mm, moderately hairy; pappi of 6–8 entire, aristate scales 1.3–2.2 (–2.7) mm. 2n = 32.
