Flowers: Heads in dense subglobose glomerules at tips of branchlets, each 2-3 mm high, involucral bracts deeply embedded in loose wool, only scarious tips showing, scarious part usually obtuse, often denticulate; flowers and pappus bristles about equaling longer involucral bracts; pappus falling separately or in groups.
