Leaves ovate-triangular or triangular, 4.3–12 cm long, 2–6.5 cm wide, base truncate to cordate, margins coarsely apiculate-dentate or bidentate, apex obtuse to subacute or acuminate, sometimes with 2 (or very rarely 4) much smaller lateral lobes, finely pubescent, mostly on veins, especially beneath, to glabrous or almost so, narrowly petiolate with the petiole auriculate at the base.. Capitula discoid, numerous in divaricately-branched terminal and axillary corymbs forming large, lax, pendent thyrsoid panicles; involucre cylindrical, 4–5.5 mm long, 2.5–3.5 mm in diameter; bracts of calyculus 3–5, lanceolate to broadly lanceolate, 1.5–2 mm long, floccose or ciliate or glabrous; phyllaries 8–13, green, 3.5–5 mm long, sparsely pubescent or glabrous.. Ray florets absent; disc florets pale creamy yellow to yellow, corolla 3–5 mm long, tube expanded above the middle, glabrous, lobes 1–1.2 mm long.. Achenes 2.5–3 mm long, ribbed, hairy; pappus white, 3–5.5 mm long.
More
A much-branched slender herbaceous scrambler, the internodes, including those of the inflorescence branches, markedly zigzag, stems and leaves glabrous to thinly and minutely pubescent. Leaves up to 8 x 7 cm but often only half that size, deltoid to deltoid-hastate, apex acute to acuminate, base more or less cordate to truncate, margin irregularly dentate or denticulate, petioles one third to half the length of the blade, often auricled at the base. Heads discoid or rayed, many in divaricate corymbose-panicles terminating the branchlet or short axillary peduncles. Involucre turbinate, bracts 5-8, 3-4 mm long, a little shorter than the disc, swollen at the base, nerves resinous, calyculus bracts few, short. Rays, when present, 1(-4), they and the disc bright yellow, corolla lobes of disc flowers each with a median resinous line. Achenes 2 mm long, cylindric, ribbed, hispid between the ribs.
Perennial, herbaceous scrambler, glabrous to ± pubescent. Stems slender, internodes zigzag, ± glabrous, up to 2.5 m long. Leaves deltoid to deltoid-hastate, up to 80 mm long, base ± cordate, margins dentate or denticulate; petioles ± 30-40 mm long, base often auricled. Inflorescence a branched, corymbose panicle, terminating branchlets. Capitula discoid, bright yellow; involucre turbinate; bracts 5-8, 3-4 mm long; calyculus bracts few, short. Flowering time Apr.-July. Cypselae cylindrical, 2 mm long, ribbed, furrows hispid.
