Information

stem herbaceous, erect, ribstriate, cobwebbed or glabrate, virgate, corymboso-paniculate at the apex; leaves lanceolate, sharply and coarsely inciso-serrate, acuminate, tapering at base almost into a petiole, glabrate and green above, cano-tomentose beneath, the petiole produced at base (in var. α.) into narrow or obsolete, somewhat denticled stem-wings; corymb very compound, pedicels scaly; inv. of many scales, amply calycled, glabrous; disc-fl. 40–50, rays 8–10; achenes glabrous. Stem 2–3 ft. high. Leaves 3–4 inches long, 1/4– 1/2 inch wide. The stem wing is very narrow at best, and often obsolete, if Drege's specimens all belong to the same species. This species is very closely related to S. juniperinus, but the leaves are not ear-clasping, and the fl. heads are smaller.
