Higher Taxonomy
Common Name: MUSTARD FAMILY Habit: 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. Genera In Family: +- 330 genera, 3780 species: worldwide, especially temperate. Note: 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 NCoR, Carrichtera annua (L.) DC. in SCo, Iberis sempervirens L., Iberis umbellata L. in PR, Teesdalia coronopifolia (Bergeret) Thell., Teesdalia nudicaulis (L.) W.T. Aiton in southern NCoRO, CCo. Cardaria, Coronopus moved to Lepidium; Caulostramina to Hesperidanthus; Guillenia to Caulanthus; Heterodraba to Athysanus; California taxa of Lesquerella to Physaria; Malcolmia africana to Strigosella. eFlora Treatment Author: Ihsan A.

Cardamine
Habit: 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. Species In Genus: +- 200 species: temperate, worldwide. Etymology: (Greek: for cress) Note: 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. Critical 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 species concept is adopted herein.Jepson eFlora Author: Ihsan A.
