Coarse, erect, branching, rhizomatous perennial to 1 m, spiny and loosely stellate-hairy; lvs ovate in outline, 7–12 cm, half as wide, with 2–5 large teeth or shallow lobes on each side, ± spiny along the main veins, stellate-hairy on both sides, the hairs sessile with 4–8 branches, the central branch often elongate; infl several-fld, elongating at maturity and forming a simple racemiform cluster; cor pale violet to white, 2 cm wide; anthers equal; fr deadly poisonous, yellow, 1–1.5 cm, subtended but not enclosed by the mostly unarmed cal; 2n=24. Fields and waste places, especially in sandy soil, originally native to se. U.S., n. to Va. and Ky., now established as a weed n. to Vt., Ont., Mich., Minn., and westward. S. dimidiatum Raf., of Kans. to Ark. and Tex., occurs in Mo. apparently as an introduction.
