    A glabrous perennial herb with a prostrate creeping stem; rootstock semi-woody.
    Stem
    Stems up to c. 1.4 m. long, flagelliforrn, usually solitary, simple or sometimes branched, often rooting at the nodes, internodes c. 5–15 cm. long.
    Leaves
    Leaves few to numerous, ± densely crowded at the stem base and also in fascicles at the nodes, the leaf fascicles often subtended by 2 broadly ovate-reniform foliaceous bracts; basal leaves subcoriaceous, up to 11(14)-2.5(3) cm., spathulate to oblanceolate, apices rounded-obtuse, margins subentire to denticulate, rarely also sinuate-dentate to lobed, bases attenuate often subauriculate below; fascicle leaves similar but usually smaller.
    Capitulum
    Capitula solitary or few from the rootcrown and at the nodes; stalks 1–3 cm. long, simple, bracteate; involucres 10–13 x 3–4 mm. in flowering capitula, up to c. 15 x 5 mm. long in fruiting capitula, narrowly oblong-cylindrical; phyllaries imbricate, increasing uniformly from 3–4 mm. long and ovate on the outside to 13–15 mm. long and lanceolate on the inside, all eventually swollen and corky towards the base.
    Florets
    Florets 12–20 per capitulum; corollas yellow, c. 15 mm. long, ligule c. 7 mm. long, lorate.
