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
Biennial (perennial herb), glaucous distally; hairs on proximal parts simple to stalked-forked or many-branched. Leaf: basal rosetted, petioled, [entire or] dentate to pinnately lobed; cauline sessile, sagittate to clasping, dentate or entire. Inflorescence: much elongated. Flower: sepals erect, base not sac-like; petals ± white (pink or purple), not clawed. Fruit: silique, dehiscent, linear, cylindric or ± 4-angled, unsegmented; stigma entire. Seed: 130–200, 2 rows per chamber, wingless or only tip winged; cotyledons face-to-face.
2 species: North America, Eurasia, northern Africa. (Latin: tower, from orientation of overlapping leaves, fruits, giving plant a pyramidal shape) [Al-Shehbaz 2005 Novon 15:519–524]
Stem: simple, occasionally few-branched distally, (3)4–12(15) dm. Leaf: basal (4)5–12(15) cm, 1–3 cm wide, oblanceolate to spoon-shaped or oblong; cauline 2–9(12) cm, (0.5)1–2.5(4) cm wide, lanceolate to oblong-elliptic or ovate. Flower: sepals 2.5–5 mm; petals 5–8.5 mm, 1.3–1.7 mm wide, linear-oblanceolate to narrowly spoon-shaped, cream (lilac or purple). Fruit: erect, appressed, (3)4–10(12.5) cm, 0.7–1.5 mm wide; pedicel 6–16(20) mm, glabrous; style 0.5–0.8(1) mm. Seed: 0.6–1.2 mm, oblong to ± round.
Open fields, meadows, slopes; < 2800 m. California Floristic Province, Modoc Plateau; temperate North America, Eurasia, northern Africa. [Arabis glabra (L.) Bernh.; Arabis glabra var. furcatipilis M. Hopkins] Apr–Jul [Online Interchange]
