Plant herbaceous hemicryptophyte, up to 200 cm tall. Stem branched, up to 6mm diameter, green to purplish; indumentum glabrous to white-arachnoid with some white glandular hairs. Leaves petiolate, sometimes auriculate. Lamina 135.2-152.9 x 63.43-137.1, palmately veined, suborbiculate to cordate; margin dentate; greenish, often membraneous and thin, almost transparent, sometimes dense, sinus often wide and shallow, depth of sinus <0.2 x the leaf length;abaxialindumentumsparse to denselywhite-arachnoid often purple along the veins, sparse to densefiliformhairs forming alanatelayer and thick multicellular hairs mostly along the veins; adaxialindumentum lighty-dark green, smooth with very sparse stiff whitish multicellular conical hairs, that are usually thinner than the multicellular hairs of the abaxial indumentum, with acuminate apex and bulbous base, mostly along the veins; Petiole 0.5-1 x the leaf length, greenish-light purplish, indumentum glabrous. Auricles, when present, usually <0.5 x the petiole length, semicircular, decurrent on the petiole, amplexicaul, margins entire to denticulate; abaxialindumentum similar to the abaxial leaf indumentum; adaxialindumentum glabrous, dark green.Infloresence terminal, lax, branched corymbosecymes, peduncles purplish, glabrous, inflorescence bracts lanceolate-filiform, green-purplish. Capitulae 10-35, 2.46-3.03 x 2.6-4.7mm, more or less urn-shaped; involucral bracts 1.4-3.4mm x WIDTH,caniculate, green or purple becoming dark-purplish at the apex, usually glabrous white-arachnoid, sometimes with multicellular erect conical purple scales, <13, 0.1-0.3mm long, usually restricted to the apex, margin scarious, base sessile, apex acute, recurved and finely ciliate. Ray florets female, 7-8, ligules 3.37-7.6 x 1.73-3.22mm, ovate-lanceolate, 3-5 toothed, light-dark purplish very rarely white, abaxial limb paler; corolla-tube 1.3-2.23mm long, pink-light purplish. Disc florets hermaphrodite, numerous (ca. 50), deep violet-mauve, tabulate-infundibuliform; tube 2.36-3.61mm long, lobes 5, <0.7mm, acuminate. Anthers united, crowned by an oblong, blunt, membranous appendage. Style slender, filiform, smooth and hardly thickened at the base; ray floret style branches recurved, glabrous; disc floret branches recurved with a truncate papillose apex. Ray cypselae 0.55-2.1 x 0.6-0.14mm, apapilose, cylindrical-oblong, slightly compressed, 4-6 furrows, dark brown, glabrous. Disccypselae 0.7-2.9 x 0.4-0.7mm, papilose, oblong, furrows 5-7, light brown, densely covered with white thick ovate-lanceolate hairs 0.08-0.17mm long. Pappi ribbed with acutely tipped spines decurrent along the length of the pappus.
