rootstock thick and woody, subhorizontal, not woolly at the crown; radical leaves numerous, petiolate, inciso-pinnatifid, viscoso-pubescent, the lobes in several pairs, short, blunt, eroso-dentate or coarsely toothed or lobulate, the sinuses rounded; stems herbaceous, leafy, corymboso-paniculate upwards, striate, pubescent; cauline leaves ear-clasping, inciso-pinnatifid, with short, toothed lobes; corymb laxly few or several-headed, the pedicels long; heads multi-radiate; inv. nearly nude at base, of many scabrid, linear-attenuate, round-backed scales; achenes finely striate, minutely downy. Rhizome 1/2 inch thick. Root leaves (from the crown) 4–7 inches long, 1–2 inches wide; their lobes 1/2– 3/4 inch wide. Stems 1–2 feet high, fistular, pale, corymboso-paniculate; pedicels 3–4 inches long. Heads 5 lines long, as many wide. Rays yellow, spreading. Known from S. glutinosus, which it resembles in foliage, by the rootstock; from S. erosus by the non-woolly crown, &c. S.? brachyrhynchoides, DC., according to a specimen from Drege (Hb. Hk.), is surely only a dwarf state of this species. Our var β. in its typical state, with obovate, crenate leaves, and nude, subsimple stems, looks different, but Dr. Pappe's specimens, all collected in the same spot, vary with deeply cut leaves, closely approaching those of the common variety. Dillenius figure, above quoted, is an excellent representation of the normal form.
