    Stems up to c. 1(2) m. tall, hollow, leafy throughout or leaves ± crowded below, divaricately branched above; branches up to c. 50(65) cm. long, ascending.
    Leaves
    Leaves up to c. 24 x 9.5 cm., decreasing in size towards the stem apex, broadly oblanceolate-elliptic in outline, runcinate or remotely pinnately-lobed, apices obtuse-acute to rounded, margins strongly acicular-denticulate, bases sessile to subauriculate, midrib prominent beneath.
    Capitulum
    Capitula numerous, subsessile to shortly-stalked, singly or in clusters of 2–8 spaced along the branches.
    Involucre
    Involucres c. 10 x 2.5 mm. in flowering capitula, up to c. 12 x 4 mm. in fruiting capitula, conical-cylindric at first later spreading.
    Phyllaries
    Phyllaries several-seriate, grading into the bracteoles of the capitulum stalk; the outer series imbricate increasing ± uniformly in length from c. 1.5–5 mm., then abruptly to 9–12 mm. long in the innermost, broadly ovate-acuminate on the outside and narrowly lanceolate-acute inside, all with a distinct hyaline margin, the midribs becoming swollen and corky towards the base.
    Florets
    Florets 20–26 per capitulum; corollas yellow, 11–13 mm. long, ligule c. 5 mm. long and lorate becoming purplish.
    Fruits
    Achenes grey-black when ripe, 3–4 mm. long, subcylindric-ellipsoid somewhat flattened, constricted above or drawn out into a short distinct apical beak, ± 4-angular with ribs on the angles and 2 secondary ribs between the angles, ribs sharply rugose-muricate; pappus heterogeneous, white, copious, c. 7 mm. long, composed of stiff barbellate setae intermixed with numerous filamentous hairs.
