stemless; root tuberous, crown very thick, woolly; radical leaves shortly petioled, glabrous, lyrato-pinnatifid, the lobes in several pair, with rounded interspaces, shortly oblong, lobulate and mucronato-denticulate, the uppermost confluent; scapes rigid, striate, much longer than the leaves, one-headed; inv. lobes and rays about 8; achenes silky; pappus pale tawny. Tuber globose or oblong; crown 3/4 in. diam. Leaves 4–6 inches long, 1 in. wide; lobes 1/2– 3/4 in. long, 4–5 lines wide. Scapes 6–10 in. long. The rays, in Ecklon's specimens here described, seem to my eye to have been yellow; but DC. calls them blueish (cærulescentes).
