Herbs annual or perennial. Trichomes stalked, glandular, mixed with eglandular simple ones. Stems leafy or not. Basal leaves petiolate, rosulate or not, sinuate-dentate, pinnatifid, or pinnatisect, rarely entire. Cauline leaves absent or shortly petiolate, not auriculate, similar to basal ones. Racemes ebracteate, elongated in fruit, rarely flowers solitary on long pedicels from axils of rosette leaves. Sepals ovate, oblong, or linear, erect, base of lateral pair strongly saccate. Petals yellow or purple or lavender, much longer than sepals; blade broadly obovate, obcordate or rarely oblanceolate, apex emarginate or rarely obtuse; claws strongly differentiated from blade. Stamens 6, strongly tetradynamous; filaments not dilated at base; anthers narrowly oblong or linear, obtuse at apex. Nectar glands 2 or 4, lateral, intrastaminal or 1 on each side of lateral stamen; median glands absent. Ovules (5-) 10-25(-30) per ovary. Fruit breaking into 1-seeded units, lomentaceous, linear, terete, sessile, slightly to strongly torulose or submoniliform; units indehiscent, with a thick corky or woody wall; replum flattened, persisting after segments fall off; septum becoming corky and splitting at middle; style 1.5-21 mm, beaklike; stigma conical, 2-lobed, lobes decurrent, strongly connivent. Seeds uniseriate, wingless, oblong; not mucilaginous when wetted; cotyledons accumbent. [more]
Herbs annual. Trichomes eglandular, simple, mixed with glandular ones. Stems erect, simple basally, often branched above. Basal leaves petiolate, not rosulate, sinuate-dentate, dentate, or rarely pinnatisect. Cauline leaves similar to basal ones, uppermost entire, subsessile. Racemes few flowered, ebracteate, elongated in fruit. Fruiting pedicels thickened, ascending or subdivaricate. Sepals oblong-linear, connivent, erect, base of lateral pair saccate. Petals purple or whitish, longer than sepals; blade linear-oblanceolate, apex obtuse; claw obscurely differentiated from blade. Stamens 6, erect, tetradynamous; filaments not dilated at base; anthers ovate, obtuse at apex. Nectar glands 4, lateral, 1 on each side of lateral stamen; median glands absent. Ovules 10-40 per ovary. Fruit dimorphic siliques, linear, sessile, torulose, glabrous; lowermost fruit indehiscent, terete, corky, breaking into 1-seeded units; upper fruit dehiscent, latiseptate, with obscurely veined leathery valves; replum rounded; septum corky in lower fruit, opaque, complete, and veinless in upper ones; style to 8 mm, stout, cylindric or subconical; stigma capitate, 2-lobed, lobes connivent. Seeds uniseriate, broadly winged, oblong or orbicular, strongly flattened; seed coat smooth, not mucilaginous when wetted; cotyledons accumbent. [more]
