Leaves ± numerous, mostly basal, often rosulate, patent-ascending, up to c. 12(19) x 1(2.3) cm. Lower leaves very narrowly-oblanceolate to linear-elliptic, remotely lobed to sinuate-dentate or sharply denticulate, sometimes entire, attenuate-acute apically, glaucous; lobes up to c. 2.5 x 0.5 cm., recurved, narrowly lanceolate.
    Capitulum

    Involucre
    Involucres up to c. 19 x 9 mm. in fruiting capitula, cylindric-campanulate, white-lanate below, the receptacle becoming somewhat swollen.
    Phyllaries
    Phyllaries olive-green, glaucous, imbricate; the outermost c. 3 mm. long, ovate, lanate and often also patent-setose outside, semi-coriaceous; the innermost c. 15 x 2 mm. in flowering capitula, increasing to c. 19 mm. in fruiting capitula, glabrous, or setose on the midribs and apices, membranous, becoming involute.
    Florets
    Florets numerous.
    Corolla
    Corollas yellow, c. 15 mm. long, pubescent about the junction between the tube and ligule; ligule c. 4 mm. long, strap-shaped.
