Plants usually robust. Flowering stems branched, (rarely bearing bulbils in place of flowers), 25-85 cm. Leaves in basal rosette and cauline, basal unlobed or 3-5-lobed, never deeply lobed, cauline (2-3+), alternate, often 3-4-lobed, much reduced, similar to basal, (rarely with axillary bulbils); stipules small, not decurrent on petiole, (margins fimbriate); petiole usually to 25 cm; blade green, orbiculate, surfaces hairy. Inflorescences 1-3, erect, 3-5(-25)-flowered racemes, 2(-3)-branched, (10-85 cm). Pedicels equaling or shorter than hypanthium, (flowers long-pedicellate). Flowers persistent, fragrant, horizontal; hypanthium narrowly campanulate with obtuse base, usually not elongating in fruit, throat open, (length 2 times diam.); sepals erect in bud, widely spreading after anthesis, triangular; petals (completely exserted), widely spreading, white, ovate-elliptic, narrowly clawed, usually unlobed with serrations at base, sometimes 3-5-lobed, 4-7 mm, ultimate margins entire; ovary to 1/2 inferior; styles slightly exerted in fruit; stigma papillae apical. Seeds 0.3-5 mm, tuberculate (tubercles in 3-19 rows, spinelike). 2n = 14, 28, 35, 42.
