Roughly hairy, perennial, 1–4 ft. high, either erect and much branched, or ascending from a decumbent base, branched from the crown or the lower part of stem. Branches pale, variably hairy, sometimes leafy to the summit, sometimes ending in a naked peduncle, 4–6 inches long, each branch usually bearing a fl.-head. Heads 3/4–1 inch across, with very many flowers. Pappus dirty-white, the outer of a few short lin.-lanceolate bristles. Corolla externally scabrous, especially on the reflexed, linear-lanceolate lobes.—This has the achenium of a Decaneurum, DC., and the habit of V. simplex, Less.
