woolly on the crown of the root, viscoso-pubescent; radical leaves numerous, petioled, oblong or obovate-oblong, obtuse, bluntly inciso-pinnatifid, with short, toothed lobes and rounded interstices, or repando-dentate; stem scape-like, nude above, with a few distant, small, sessile, toothed or pinnatifid leaf-scales, simple and one-headed or branched, 2–3-headed; rays numerous, yellow; inv. sparingly calycled, of many linear, acuminate, scabrous-pubescent scales; achenes terete, minutely pubescent. With the foliage of S. hastulatus, this has usually a simple, one-headed, scape-like stem, and may always be known from the dwarf states of that species by the woolly crown of the root.
