absent or simple.

Racemes

(corymbose), greatly elongated in fruit.

usually ebracteate, often elongated in fruit.

Flowers

sepals (sometimes persistent), erect, oblong [linear], (connivent), lateral pair saccate basally;

petals cream or yellow (with dark brown or purple veins), broadly obovate, claw differentiated from blade (± equal to sepals, apex obtuse or emarginate);

stamens strongly tetradynamous;

filaments not dilated basally;

anthers oblong or linear, (base sagittate, apex obtuse);

nectar glands (4), distinct, median pair present.

actinomorphic;

sepals erect, ascending, or spreading, lateral pair saccate or not basally;

petals white, cream, yellow, pink, lilac, lavender, or purple, claw present, often distinct;

filaments unappendaged, not winged;

pollen 3-colpate.

Fruiting pedicels

Fruits

siliques, dehiscent, sessile, segments 2, linear or oblong [elliptic], not torulose, terete or slightly 4-angled; (terminal segment indehiscent, flattened and ensiform, seedless);

valves each with prominent midvein, (coriaceous), glabrous, hirsute, or hispid;

replum rounded;

septum complete, (membranous);

ovules 10–50 per ovary; (style obsolete);

stigma conical, 2-lobed (lobes connivent, decurrent).

silicles or siliques, dehiscent or indehiscent, usually segmented, usually latiseptate or terete (subterete or 4-angled in Erucastrum) [angustiseptate];

ovules (1–)2–276[–numerous] per ovary;

style usually distinct (absent in Cakile, obscure in Carrichtera, obsolete in Eruca);

stigma entire or strongly 2-lobed (sometimes slightly 2-lobed in Cakile).

Seeds

biseriate, plump, not winged, [sub]globose or ovoid;

seed coat (minutely reticulate), mucilaginous when wetted;

Discussion

Species 1.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Genera 46, species ca. 245 (13 genera, 28 species in the flora).

The generic boundaries in Brassiceae are largely artificial, and the number of genera may be substantially reduced.
