Characteristics

Herbs annual or rarely biennial, mostly glabrous throughout, usually glaucous. Trichomes absent or rarely as minute papillae on pedicels. Stems erect, simple. Basal leaves subsessile, subfleshy, not rosulate, simple, entire. Cauline leaves sessile, cordate-amplexicaul or rarely auriculate at base, entire. Racemes ebracteate, elongated in fruit. Fruiting pedicels slender or thick and as wide as fruit, erect or divaricate. Sepals oblong or linear, erect or ascending, base of lateral pair not saccate or strongly saccate. Petals yellow or white, rarely with purple veins, longer than sepals; blade obovate, oblong, or oblanceolate, apex obtuse; claw somewhat differentiated from blade. Stamens 6, tetradynamous; filaments not dilated at base; anthers narrowly oblong, obtuse at apex. Nectar glands 2, lateral, semiannular, rarely 1 and confluent; median glands absent or rarely present. Ovules 10-50 per ovary. Fruit dehiscent siliques, linear, terete, 4-or 8-angled, or latiseptate; valves veinless or prominently veined, smooth or torulose; replum rounded; septum complete; style to 1.5 mm; stigma capitate, entire or decurrently 2-lobed. Seeds uniseriate, wingless, oblong or elliptic, plump; seed coat reticulate, mucilaginous or not when wetted; cotyledons incumbent or rarely subconduplicate.
More
Plants not scapose; (usually glaucous). Stems erect, unbranched or branched proximally. Leaves basal and cauline; subsessile or sessile; basal not rosulate, subsessile, blade margins usually entire; cauline blade (base cordate-amplexicaul or, rarely, auriculate), margins usually entire, rarely crenulate. Racemes (corymbose, several-flowered). Fruiting pedicels ascending, stout (almost as thick as fruit, or, rarely, much narrower). Flowers: sepals oblong; petals usually narrowly obovate, rarely oblanceolate, claw differentiated from blade [undifferentiated], (apex obtuse); stamens slightly tetradynamous; filaments not dilated, slender; anthers oblong (base slightly sagittate); nectar glands lateral, median glands often absent. Fruits sessile, linear, torulose, 4-angled or terete; valves each with prominent midvein; replum rounded; septum complete; stigmas capitate-flattened, entire. Seeds not winged, oblong [ellipsoid]; seed coat (papillose), copiously mucilaginous (granular) when wetted; cotyledons incumbent. x = 7 [9].
Sep erect, saccate at base; pet long-clawed, bright yellow to nearly white; short stamens subtended by a U-shaped gland; ovary cylindric, gradually tapering to the short style; ovules many; stigma capitate; fr elongate, slender, many-seeded, terete or 4-angled, tapering to a short beak; seeds in 1 row in each locule, oblong, granular-roughened; annual or biennial glabrous herbs, often glaucous; lvs entire, at least the upper cordate-clasping. 6, w. Eurasia, Mediterranean.
Annual herbs, glabrous. Sepals erect, dimorphic, the medians saccate. Petals long-clawed. Stamens 6. Nectariferous glands 2 or 4, usually crescent-shaped outside base of short stamens, median glands absent. Siliqua dehiscent, angled, beaked; valves with prominent midrib. Seeds in 1 row per locule. Cotyledons sub-conduplicate; radicle incumbent.
