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.

Common Name: YELLOW CRESS Habit: Annual to perennial herb, occasionally with caudex or rhizome; hairs simple or 0. Stem: prostrate to erect, branched or not, leafy. Leaf: basal rosetted or not, simple, entire or dentate to 1--3-pinnately divided; cauline petioled or sessile, generally lobed to sagittate at base, entire to dentate or pinnately lobed. Inflorescence: elongated or congested; bracts 0 [rarely throughout]. Flower: sepals erect to spreading, base not sac-like, generally deciduous (persistent); petals present (vestigial or 0), yellow [white or pink], generally not clawed. Fruit: silique, linear or narrowly oblong, or silicle, spheric to ovoid or broadly oblong; dehiscent, unsegmented; stigma entire or +- 2-lobed. Seed: 10--300, 1(2) row(s) per chamber, generally wingless. Etymology: (Latinized Old Saxon: for these or perhaps other crucifers) Note: Other taxa in TJM (1993) moved to Nasturtium. eFlora Treatment Author: Ihsan A.

MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
