suffruticose, cobwebby-tomentose, much branched, the branches canescent, corymbiferous; leaves half-clasping and often unidentate at base, linear-subulate, subpungent mucronate, with revolute margins, punctulate and glabrate (the younger cobwebby) above, tomentose beneath; corymb lax, compound, the pedicels copiously scaly below the head; inv. calycled, of 14–16 glabrous, barbellate scales; heads discoid, 20–30-fl.; achenes cano-pubescent. A much-branched bush, 1–2 feet high, all the young parts copiously flocculent. Leaves 1–2 inches long, 1 line wide, from a broadish base, which is very frequently produced at each side into a tooth-like ear. Corymbs spreading, 10–20-headed. Heads 3 lines long. It much resembles S. rosmarinifolius, but has discoid heads, and broad-based, often auricled leaves, &c. It is still nearer to S. juniperinus, from the narrow-leaved forms of which it only differs by the discoid heads.
