Flora of North America species comparison

erect or decumbent, branched basally [and distally] (leafy or not).

(0.5–)1–4(–5.6) dm.

basal and sometimes cauline;

petiolate;

basal not rosulate [rosulate], blade margins sinuate-dentate, [pinnatifid, or pinnatisect, rarely entire];

cauline absent or shortly petiolate, blade (base not auriculate) margins often entire.

(often withered by flowering);

petiole (0.5–)1–2(–4) cm;

blade oblanceolate or oblong, (1.5–)2.5–8(–13) cm × (4–)8–20(–30) mm, base cuneate or attenuate, apex acute, surfaces glandular.

similar to basal, distalmost subsessile, blades smaller distally.

(corymbose [or, rarely, flowers solitary on long pedicels from axils of rosettes], several-flowered), slightly or considerably elongated in fruit.

sepals linear [ovate, or oblong];

petals usually purple or lavender [yellow], rarely white, (much longer than sepals), oblanceolate [broadly obovate or obcordate], claw strongly differentiated from blade, (apex obtuse [emarginate]);

stamens strongly tetradynamous;

filaments not dilated basally;

anthers narrowly oblong [linear], (apex obtuse);

nectar glands (2 or 4), lateral, intrastaminal or each side of lateral stamen.

sepals purplish, (3–)4–5(–6) × 0.5–0.7 mm;

petals 8–10(–12) × 1–2 mm, claw 6–7 mm;

filaments 4–6(–7) mm;

anthers ca. 1.5 mm.Fruits slightly curved-ascending, (1.4–)1.8–2.5(–3) cm × 1.5–2 mm, with 8–12 constrictions on each side;

style (6–)10–18(–22) mm.

divaricate, stout [slender] (nearly as thick as fruit).

(2–)3–5 mm, glandular.

sessile, segments 2, linear, slightly [strongly] torulose or submoniliform, terete; (segments breaking into 1-seeded units, lomentaceous with thick, corky, or woody wall);

valves usually glandular, rarely eglandular;

replum flattened, (persistent after segments fall off);

septum becoming corky, splitting at middle;

ovules 5–30 per ovary; (style beaklike);

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

flattened, not winged, oblong;

seed coat not mucilaginous when wetted;

cotyledons accumbent.

brown, 1–1.4 × 0.8–1 mm.
