Description

Perennial. Rhizome about 1 cm thick, annually producing solitary herbaceous stem from apex; previous year's stems preserved as fragments with remnants of leaves; adventitious roots slender, cord-like to almost filiform, fewer. Stem 90-150 cm high, 5-10 mm thick at base; weakly branched near apex, sulcate, fistular, entirely or almost entirely glabrous. Leaves petiolate; lower leaves, on long petioles as long as or exceeding lamina, middle leaves on shorter petioles almost half as long as lamina, and upper leaves short-petiolate or more or less sessile; lamina very thin, almost chartaceous, with distinct network of veins, rotund-triangular or triangular, more or less acuminate, cordate-hastate at base, margin broadly but shallow sinulate or coarsely large and obtusely toothed, with thin soft spinose processes; less often petioles with small leafy auricles. Capitula ovoid or campanulate, 5-10 mm wide and about 1 cm long, few, on long peduncles slightly expanded above (below capitula), in lax paniculate-corymbose inflorescence; sometimes capitula arising from axils of upper leaves, less often only few or solitary. Involucral bracts two- to four-rowed linear-lanceolate, dirty dark green to almost black. Capitula with 30-35 florets; corolla light- or bright-yellow, two times or more as long as capitulum. Achenes about 4 mm long and 1 mm wide, slightly flattened, almost terete or indistinctly four- or five-angled, slightly narrowed toward: apex and near base, usually with four or five more strongly protecting ribs and indefinite number of, less conspicuous ribs, dark brown, densely covered with very short, light-colored hairs (under high magnification!); pappus of snow-white, almost entirely smooth, persistent hairs, slightly exceeding achene.
