• Description

  Species Description - Plants 2–10 dm from a branched caudex, covered with minute, stiffly spreading viscidulous hairs, or glabrate below; lvs basally disposed, the larger ones broadly oblanceolate to elliptic or obovate, serrate, obtuse or acute, mostly 5–15 × 1–3.5 cm, the others more lance-elliptic to lance-linear and entire; infl thyrsoid, dense, often leafy-bracteate, with stiffly ascending, not at all secund branches, or unbranched in small plants; invol 3–5 mm, its bracts narrow, ca 0.5 mm wide or less at midlength, with slender, acuminate, ± subulate tip; rays 9–16; disk-fls (8–)10–18; achenes glabrous or occasionally sparsely hairy; 2n=18. Mostly in open places, generally in sandy or acid soil or rocks; N.S. and s. Que., s. through the coastal and Appalachian states to Fla. and La. Most of our plants are var. puberula, as principally described above. The well marked var. pulverulenta (Nutt.) Chapm., on the coastal plain from s. Va. to Fla. and Ala., has more numerous and smaller lvs (the middle cauline ones commonly 1–4 cm) that are less hairy on the upper surface than on the lower, and has more evenly tapering, scarcely subulate invol bracts to 0.75 mm wide at midlength. (S. pulverulenta)
