Annual herb, up to 1.2 m high; erect, often grey-pubescent. Stems with lateral branches commonly overtopping or at least equalling main axis. Leaves alternate, sessile; blade linear to narrowly elliptic, up to 100 x 10 mm, often twisted near base, apex acute, base cuneate, margins entire or dentate, often undulate, scabrid-pubescent on both surfaces. Heads disciform, > 10 mm in diameter, few, long-pedunculate, grouped in terminal, lax, leafy panicles. Involucral bracts 2-or 3-seriate, imbricate, linear, margins of middle bracts light-coloured and narrower than central dark portion, apices sometimes tipped reddish purple. Flowers: outer florets female, minutely radiate, 4-or more seriate; disc florets bisexual, with corolla 5-lobed, whitish or yellowish green; Oct.-Jun. Fruit with cypsela narrowly elliptic, compressed, thinly hairy. Pappus of many, dirty white, pinkish or reddish brown, barbellate bristles.
Erect, roughly hairy annual herb up to 1.2 m tall, stems very leafy, often simple below, branching above into the compound inflorescence, these lateral branches [as 'braches'] commonly overtopping or at least equalling the main axis. Leaves sessile, lanceolate to elliptic, up to 10 x 1 cm, but often not more than 5 x 0.5 cm, twisted near the base, margins entire or toothed, often markedly undulate as well. Heads disciform, usually more than 1 cm across when pressed. Involucral bracts in c. 3 series, linear-lanceolate, acuminate, dark with pale scarious margins, pilose. Achenes c. 1.75 mm long, narrowly elliptic, compressed, thinly hairy, margins thickened. Pappus of dirty white or pinkish scabridulous bristles.
Plants often gray-pubescent. Leaves entire to variously incised, margins generally strigulose. Capitulescence corymbiform with lateral branches overtopping the main axis or less commonly thyrsoid-paniculate, pyramidal; capitula generally few, long-pedunculate, generally disciform; involucre basally broadened, phyllaries sometimes reddish purple-tipped, central green portion of mid-series phyllaries generally broader than the light-colored phyllary margin; marginal florets in 4 or more series, corollas of marginal florets tubular, rarely subradiate; disk corollas 5-lobed; fruiting receptacle ca. 4 mm broad; pappus sometimes reddish brown.
Erect, roughly hairy, annual herb, up to 1.2 m high, lateral branches equal to or overtopping main stem. Leaves alternate, sessile, lanceolate to elliptic, up to 100 mm long, but mostly only up to ± 50 mm, twisted near base, margins entire or toothed, often undulate as well. Capitula disciform, > 10 mm in diam., pedunculate, arranged in compound, paniculate synflorescence. Receptacle epaleate. Outer female florets filiform, multiseriate, pale yellow. Disc florets bisexual, tubular, pale yellow. Flowering time Sept.-Apr. Pappus of many dirty white or pinkish scabridulous bristles. Cypselae narrowly elliptic, compressed, thinly hairy.
Erect, roughly hairy annual, up to 1.2 m tall, lateral branches equalling or overtopping main stem.

Flowerheads disciform, pedunculate, arranged in a compound, paniculate synflorescence, pale yellow; outer female flowers filiform; disc florets bisexual. Cypselas narrowly elliptic, compressed, thinly hairy; pappus of numerous dirty white or pinkish scabridulous bristles.
A robust herb. It is erect and grows from seed each year. The stems are hairy. They are 1 m long. The leaves are alternate and grey green. They are narrow and have small hairs. There can be fine teeth along the edge. The flowers are a the top and in pales yellow flower heads. The fruit are oblong. They have pale brown bristles. The correct name is probably now Erigeron bonariensis L.
