Annuals; puberulent. Stems simple from base, erect, (paniculately) branched beyond base or distally, 2–6 dm. Basal leaves (soon withered, often before anthesis); not rosulate; blade dentate to pinnatifid. Cauline leaves shortly petiolate to subsessile; blade narrowly oblanceolate to linear, 1–3.3 cm × 1–4 mm, base attenuate, not auriculate, margins entire. Racemes (often paniculate), considerably elongated in fruit; rachis glabrous or puberulent, trichomes straight, cylindrical. Fruiting pedicels divaricate-ascending to horizontal, straight, (terete), 2–3.5 × 0.1–0.15 mm, puberulent adaxially.
