Annual to shrub; sap pungent, watery. Leaf: generally simple, alternate; generally both basal, cauline; stipules 0. Inflorescence: generally raceme, generally not bracted. Flower: bisexual, generally radial; sepals 4, generally free; petals (0)4, forming a cross, generally white or yellow to purple; stamens generally 6 (2 or 4), 4 long, 2 short (3 pairs of unequal length); ovary 1, superior, generally 2-chambered with septum connecting 2 parietal placentas; style 1, stigma entire or 2-lobed. Fruit: capsule, generally 2-valved, "silique" (length >= 3 × width) or "silicle" (length < 3 × width), dehiscent by 2 valves or indehiscent, cylindric or flat parallel or perpendicular to septum, segmented or not. Seed: 1–many, in 1 or 2 rows per chamber, winged or wingless; embryo strongly curved.
± 330 genera, 3780 species: worldwide, especially temperate. [Al-Shehbaz et al. 2006 Plant Syst Evol 259:89–120] Highest diversity in Mediterranean area, mountains of southwestern Asia, adjacent central Asia, western North America; some Brassica species are oil or vegetable crops; Arabidopsis thaliana used in experimental molecular biology; many species are ornamentals, weeds. Aurinia saxatilis (L.) Desvaux in cultivation only. Aubrieta occasional waif in central North Coast Ranges, Carrichtera annua (L.) DC. in South Coast, Iberis sempervirens L., Iberis umbellata L. in Peninsular Ranges, Teesdalia coronopifolia (Bergeret) Thell., Teesdalia nudicaulis (L.) W.T. Aiton in southern Outer North Coast Ranges, Central Coast. Cardaria, Coronopus moved to Lepidium; Caulostramina to Hesperidanthus; Guillenia to Caulanthus; Heterodraba to Athysanus; California taxa of Lesquerella to Physaria; Malcolmia africana to Strigosella. —Scientific Editors: Douglas H.

Key to Brassicaceae
Annual to perennial herb, occasionally subshrub; hairs simple or 0. Leaf: rosetted or not, petioled, entire to pinnately lobed; cauline sessile, not lobed basally. Inflorescence: dense panicles, not elongated. Flower: bilateral; sepals erect to ascending, base not sac-like; petals white to pink or purple, generally clawed, inner pair smaller than outer. Fruit: silicle, round, ovate to obcordate, flat perpendicular to septum, dehiscent, unsegmented, winged; style distinct, stigma entire or 2-lobed. Seed: 2, narrowly winged.
± 27 species: Europe, northern Africa, southwestern Asia. (From Iberian Peninsula) Iberis sempervirens L. a waif in gardens.
Plant glabrous. Stem: 1–5.5(7) dm, branched distally. Leaf: proximal, middle cauline 2–5(6.5) cm, linear-oblanceolate, entire. Inflorescence: not elongated in fruit. Flower: sepals 3–5.5 mm; petals white to pink or purple, inner pair 2–5 mm wide, outer pair 10–16 mm, 5–7 mm wide. Fruit: (7)8–10.5 mm, 5–8 mm wide, ovate, notched at tip; valves forming acute wing. Seed: 2–3 mm, ovate, narrowly winged.
