A perennial, low-growing, very hairy weed, spreading by means of vigorous and rapidly growing leafy stolons. Leaves basal, spatulate or oblong, blunt at the apex, narrowed at the base, usually entire, 2 to 5 inches long, one-fourth to 1 inch wide, very hairy. Flowers borne on a slender, hairy, leafless stem (rarely with one or two small leaves), 6 to 20 inches high, the heads of flowers bright orange-red in color, one-half to 1 inch broad, few or several in a rather dense inflorescence or cluster at the summit of the stem, the upper part of the stem and the inflorescence thickly dotted with black, glandular-tipped hairs. Flowers of the head all alike, with five-toothed, strap-shaped corollas. Involucres one-third to one-half of an inch high, composed of linear-lanceolate green bracts, densely covered with black hairs, the bracts arranged in two or three series.
