Herbs with fusiform or cylindric, fleshy or woody roots. Stems 50-120(-200) cm tall. Basal leaves few; petiole to 60 cm, broadly expanded at base; leaf blade broadly oblong, oblong-lanceolate, or ovate, (10-)20-45(-60) × (3-)5-12(-17) cm, coarsely crenate or rarely pinnatifid. Lower and middle cauline leaves shortly petiolate, pinnatifid or pinnatisect, with oblong to linear-oblong lobes, smaller than basal leaves; upper cauline leaves sessile or shortly petiolate, linear to linear-lanceolate, base cuneate or attenuate, margin serrate, crenate, or rarely entire. Fruiting pedicels ascending, slender, 0.8-2 cm. Sepals ovate, 2-4 mm. Petals obovate or oblanceolate, 5-7(-8) mm; claw to 1.5 mm. Filaments 1-2.5 mm; anthers ovate, 0.5-0.8 mm. Ovules 8-12 per ovary. Mature fruit rarely produced, ovate, oblong, or suborbicular, 4-6 mm, few seeded; style obsolete or to 0.5 mm; stigma capitate, well developed. Seeds not seen. Fl. May-Jul. 2n = 32.

Cauline leaves: proximal shortly petiolate, blade oblong to linear-oblong (lobed), smaller than basal, margins pinnatifid or pinnatisect; distal sessile or shortly petiolate, blade linear to linear-lanceolate, base cuneate or attenuate, margins usually serrate or crenate, rarely entire. Racemes to 40 cm. Fruiting pedicels ascending, 8-20 mm. Flowers: sepals 2-4 mm; petals obovate or oblanceolate, 5-7 (-8) mm, claw to 1.5 mm; filaments 1-2.5 mm; anthers 0.5-0.8 mm. Fruits (rarely produced), 4-6 mm; style obsolete or to 0.5 mm; stigma well-developed. Seeds compressed (often not produced, rarely to 4 per locule). 2n = 32.
"Erect perennial to 1 m from thick roots; lower lvs long-petioled, the blade oblong, 1–3 dm, cordate at base; upper lvs smaller, short-petioled to sessile, lanceolate; racemes several, terminal and from the upper axils; pet 6–8 mm; mature pedicels ascending, 8–12 mm; frs obovoid, bilocular, to 6 mm, or falling early; style 0.3 mm, with broad, persistent stigma; seeds rarely maturing; 2n=32. Native of se. Europe and w. Asia; commonly cult. and widely escaped into moist soil. May–July. (A. armoracia; A. lapathifolia; Radicula armoracia)"
