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. Goldman, Bruce G. Baldwin.
Key to Brassicaceae
Annual to subshrub [shrub]; hairs sessile, appressed, 2–5(8)-rayed. Leaf: basal rosetted, petioled, entire, dentate, or pinnately lobed; cauline sessile or petioled, bases not lobed. Inflorescence: elongated. Flower: sepals oblong to linear, erect, base of lateral pair sac-like or not; petals clawed, yellow or orange (white, purple, or brown). Fruit: silique, dehiscent, linear, cylindric, 4-sided, or flat parallel or perpendicular to septum, unsegmented; stigma entire or 2-lobed. Seed: 15–100, in 1 or 2 rows, plump or flattened, oblong, winged or not.Key to Erysimum
± 150 species: North America, Eurasia, northern Africa. (Greek: to help or save, from alleged medicinal properties of some species) [Rossbach 1958 Madroño 14:261–267] Fls, fruit, basal leaves needed for identification. All native California taxa related to Erysimum capitatum; hybridization blurs limits of some species.

Annual. Stem: (0.4)1.5–4.5(7) dm. Leaf: (2)5–12(17) mm wide, linear to narrowly oblanceolate or oblong, wavy, dentate or shallowly wavy, flat, hairs 2(3)-rayed. Flower: sepals 4–8 mm; petals 6–8 mm, 1.5–2 mm wide, light yellow, claw 3–8 mm. Fruit: (2)3–8(10) cm, 1.5–2 mm wide, 4-angled, ± constricted between seeds; valves outside with 2(3)-rayed hairs, inside glabrous or occasionally sparsely hairy, midvein distinct; style 1–4 mm; pedicel spreading, 2–4(6) mm, ± as wide as fruit. Seed: (40)50–80(90), 1–1.5 mm, oblong; wing 0 (tip winged).
