Leaves glabrous, rather thick, the basal ones obovate with a cuneate base, subor- bicular or broadly spatulate, very obtuse and round- ed at the apex, i'-3i' long, i'-a' wide, crenate- dentate, often purplish; stem leaves commonly few and sessile, spatulate to oblong, often incised or pinnatifid; heads several, corymbose, 6"-8" broad, about 3" high, slender-peduncled; involucre nearly cylindric, its principal bracts linear-lanceolate, 2"-3" long, acute, usually with 1-3 small exterior ones; rays 8-12, usually conspicuous, sometimes fewer and short; achenes glabrous; pappus white. In moist soil on banks and in woods, Maine and Ver- mont to Florida, Ohio, Michigan, Alabama and Texas. Races differ in size, leaf-form, number and size or rays. Apparently erroneously recorded from Nova Scotia and Ontario.
