Herbs, annual, to 1+ m. Stems erect, stellate-tomentose, without simple hairs. Leaves: stipules lanceolate; petiole subequal to blade; blade concolorous, broadly ovate to suborbiculate, 8–15 cm, ± as long as wide, base cordate, margins crenulate, apex acuminate, surfaces softly pubescent. Inflorescences usually solitary flowers, sometimes cymose or racemose. Flowers: calyx 10 mm, lobes not overlapping, erect in fruit, ovate; corolla pale yellow throughout, petals 8–13 mm; staminal column glabrous; style 13–15-branched. Schizocarps broadly ovoid, 15 × 20 mm; mericarps: apex spinose, spines divergent, 3–6 mm, hirsute. Seeds 3 per mericarp, 3–4 mm, minutely puberulent. 2n = 84.

Herb, annual, the stem erect, 0.3-1.2 m high, more or less tomentose, the hairs simple and/or stellate. Leaves long-petiolate, the petiole rather slender, usually longer than the blade, more or less tomentose, the stipules early caducous; blade broadly ovate to subeircular to very broadly ovate, deeply cordate at the base, more or less abruptly long-acuminate at the apex, crenulate or crenate- dentate at the margin, up to 20 cm broad, chartaceous, slightly discolor, 7- to 9-palminerved, puberulus and usually with stellate hairs on both surfaces but the indumentum usually softer and denser beneath, the veins prominent beneath. Flowers axillary and solitary, or in a few-flowered, leafy, terminal panicle, the pedicels shorter than the petioles, articulate usually above the middle, tomentose; calyx broadly campanulate, ca 10 mm long, tomentose, lobed to far beyond the middle, the lobes patent at anthesis, ovate and acute, accrescent; petals patent at anthesis, oblong-obovate, ca 10-13 mm long, yellow or orange, glabrous at the insertion of the staminal tube; androecium shorter than the calyx and corolla, the staminal tube much inflated, glabrous. Fruit broadly cylindric, umbilicate, villous to densely pubescent, the mericarps about 15, 12-15 mm long (awns excluded), long-aristate at the apex, the awns widely spreading and ca 3-5 mm long, rounded at the base, rigid-chartaceous, 3-seeded; seeds ca 3.5-4 mm long, inconspicuously foveolate and minutely puberulus.

Stout branching annual 1–1.5 m, softly hairy throughout with few-armed stellate hairs; lvs cordate, 10–15 cm long and wide, acuminate, entire or obscurely toothed, on petioles about as long; peduncles joined above the middle, elongating to 2–3 cm at maturity; fls yellow, 1.5–2.5 cm wide; head of fr 2–3 cm wide; carpels commonly 10–15, densely hairy, with conspicuous horizontally spreading beaks; 2n=42.
