Stems rather stiff, slender, somewhat rough, 1 to 3 feet high, with several spreading branches toward the summit. Leaves ovate-oblong to oblong-lanceolate, rough or pubescent, thick and somewhat rigid, clasping the stem by a deeply heart-shaped base, margins rough-ciliate and entire, the apex pointed, or the lower leaves blunt 1 to 3 inches long, those of the branches much reduced in size. Heads of flowers 1 inch broad or sometimes broader, solitary at the ends of the branches; bracts of the broadly turbinate involucres linear-oblong, finely pubescent or roughish and somewhat glandular, overlapping in several series, their green, pointed tips spreading. Ray flowers twenty to thirty, purplish blue or deep violet, one-third to one-half of an inch long; pappus tawny.
