stem rigid, erect or diffuse, branching, branches ending in a long, leafless peduncle, tomentose; leaves long-decurrent, the lowest obovate, 3-nerved, subobtuse, mucronate, upper oblong, the younger on both sides loosely woolly, the old becoming nude above, setoso-scabrid; cymes long-peduncled, very densely much-branched, leafless; heads oblong, 5–6-fl.; inv. scales erect, glabrous and glossy, oblong, concave, acute or subacute, fulvous-yellow. Very nearly allied to H. odoratissimum, from which it chiefly differs in its rather longer involucre and flowers, and the fewer number of flowers in each head, and subacute inv. scales. β. is slender, and less woolly.
