Characteristics

Plants 30–80 cm. Corms globose to slightly elongate. Stems glabrous or puberulent-villous. Leaves: basal and proximal cauline 3–5-nerved, broadly linear to linear-oblanceolate, 70–220 × 2–12 mm (largest usually distal to proximalmost), gradually reduced distally, puberulent-villous or glabrous, weakly gland-dotted. Heads borne singly or (3–26) in loose, racemiform to spiciform arrays. Peduncles 0 or (spreading to ascending) 1–8(–20+) mm. Involucres cylindro-campanulate, 12–20(–25) × 7–10 mm. Phyllaries (usually erect, sometimes spreading-reflexing on the distal 1/3) in 5–7 series, narrowly ovate-triangular and foliaceous (outer) to ovate or oblong-triangular, ± equal, glabrous or pubescent, margins without hyaline borders, stiffly to softly ciliate, apices acuminate to acute. Florets (10–)23–45(–60); corolla tubes glabrous inside (lobes adaxially hispid). Cypselae 4–5.5 mm; pappi: lengths ± equaling corollas, bristles plumose.

More

Glabrous or hairy, 3–8 dm; lvs linear or a little broader, firm, those near the base 6–25 cm × 4–13 mm, often partly sheathing, or the very lowest often smaller and deciduous; heads mostly few or even solitary, on stiff, erect peduncles or sessile; invol 12–25(–30) mm, its bracts firm, with loose or squarrose, acuminate tip; fls 20–45 per head, or up to 60 in the terminal head; inner surface of the cor-lobes coarsely hairy; pappus evidently plumose; 2n=20. Dry, open places; Del. to S.D., s. to Fla. and Tex. July–Aug. Three vars. in our range.
