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.

Turritis
Habit: 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. Species In Genus: 2 species: North America, Eurasia, northern Africa. Etymology: (Latin: tower, from orientation of overlapping leaves, fruits, giving plant a pyramidal shape) Jepson eFlora Author: Ihsan A.
