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
Perennial herb with caudex (annual or biennial); hairs stellate, ± sessile. Stem: erect to decumbent or prostrate, simple or branched distally. Leaf: basal generally rosetted, simple, entire to wavy or dentate (pinnately lobed); cauline petioled or sessile, entire to wavy or dentate, base not lobed. Flower: sepals oblong to ovate, erect or spreading, sac-like at base; petals yellow (white or ± purple), widely ovate to spoon-shaped, clawed or not. Fruit: silicle, dehiscent, spheric to ovoid, ellipsoid, oblong, or spectacle-shaped, inflated and bladdery or not, unsegmented, generally not flattened (flattened); stigma entire. Seed: 4–28(40), in 2 rows, wingless (narrowly winged).Key to Physaria
