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] perennial herb, subshrub; hairs 0 or simple, glaucous. Leaf: basal, proximal-most cauline petioled, simple to entire or 1(2)-pinnately lobed; middle, distal cauline petioled to sessile, base occasionally lobed or sagittate. Inflorescence: dense, elongated. Flower: sepals oblong to linear, spreading to reflexed, base not sac-like; petals yellow to white, long-clawed; filaments equal; anthers linear, coiled. Fruit: silique, dehiscent, linear, flat parallel to septum or cylindric, unsegmented; stalk above receptacle [0.4]0.6–2.8 cm; style 0 or short, stigma entire. Seed: 10–70, in 1 row, oblong, wingless.Key to Stanleya
