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
Annual to perennial herb, from taproots, fibrous roots, or tuber-like rhizomes; hairs 0 or simple. Leaf: alternate, opposite, or whorled; entire to palmately, pinnately lobed, or compound; cauline leaves petioled or 0, not lobed at base [lobed]. Inflorescence: elongated, bracts generally 0. Flower: sepals erect (spreading), bases sac-like or not; petals white, pink, purple, or violet. Fruit: silique, linear, flat parallel to septum, dehiscent, unsegmented; valves generally coiling when dehiscent; placental margins flattened. Seed: (4)10–80, in 1 row, wingless.Key to Cardamine
± 200 species: temperate, worldwide. (Greek: for cress) Some North American species (e.g., Cardamine californica, Cardamine nuttallii, Cardamine pachystigma) highly variable, more study needed; species treated conservatively here. Cardamine flexuosa With. a waif in gardens, nurseries.
Unabridged note: Some North American species (e.g., Cardamine californica, Cardamine nuttallii, Cardamine pachystigma) highly variable and numerous minor variants were recognized as varieties. C ritical studies of these complexes reveal that only a fraction of the overall continuous variation was formally recognized. Without detailed molecular and cytological studies, a broader sp. concept is adopted herein.
Perennial herb, glabrous or hairy at least at base; rhizome cylindric, 1–3 mm wide. Stem: 2–7(10) dm, simple or branched above. Leaf: simple, 5–15 cm, cordate or reniform, petiole 2.5–12 cm; cauline (3)5–17(23), generally simple, fleshy, petioled, 2–10 cm, 1–5.5(8.5) cm wide, reniform to cordate or ovate, distal reduced. Flower: sepals 2.5–4.5 mm; petals 7–12 mm, 4–6 mm wide, obovate, white. Fruit: ascending to erect, (2)2.5–3.7(4) cm, 1.2–2 mm wide; style 0.5–3(6) mm; pedicel ascending to spreading, (0.7)1–2 cm. Seed: 14–24, 1.6–2 mm, oblong.
2n=24. Streambanks, meadows, wet or moist areas, mixed-conifer forest; 600–3600 m. Klamath Ranges, Cascade Range, n High Sierra Nevada; to British Columbia, Wyoming, New Mexico. [Cardamine cordifolia var. lyallii (S. Watson) A. Nelson & J.F. Macbr.] May–Aug [Online Interchange]
