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.)

Key to Brassicaceae
Annual, biennial; hairs simple, rigid. Leaf: basal, proximal cauline petioled, pinnately lobed, margin dentate; distal cauline short-petioled to sessile, base not lobed. Inflorescence: elongated. Flower: sepals erect, oblong to linear, base of inner pair sac-like; petals long-clawed, yellow, white, pink, or purple, veins darker. Fruit: silique or silicle, indehiscent, linear to lanceolate, oblong, or ovoid, segmented; proximal segment short, seedless; terminal segment seeded, beaked; stigma ± 2-lobed. Seed: in 1 row, wingless.Key to Raphanus
3 species: Mediterranean. (Greek: appearing rapidly, from seed germination)
Sparsely to densely hairy. Stem: (2)3–8 dm, reflexed-hairy. Leaf: blade 3–15(22) cm, 1–5 cm wide, oblong, obovate, or oblanceolate, lyre-shaped to pinnately lobed; lateral lobes 1–4 pairs, dentate; distal cauline ± sessile, dentate. Flower: sepals 7–11 mm; petals 15–25 mm, 4–7 mm wide, claw 8–14 mm. Fruit: cylindric to narrowly lanceolate; proximal segment 1–1.5 mm; terminal segment (1.5)2–11(14) cm, (2.5)3–8(11) mm wide, woody; pedicel ascending to spreading, 0.7–2.5 cm. Seed: 2.5–3.5 mm, ovoid to oblong.
2n=18. Disturbed areas, fields; < 1100 m. California Floristic Province, Great Basin Floristic Province; North America; native to Mediterranean Europe. Hybridizes with Raphanus sativus to produce swarms highly variable in flower color and fruit constriction. Apr–Jul [Online Interchange]
