several from base, usually somewhat decumbent, (unbranched), (0.4–)0.5–2 dm.

simple or few from base, prostrate or straggling to erect, (sometimes purplish, usually unbranched), (0.5–)1–2(–3) dm.

(petiole slender, often narrowly winged);

blade obovate to orbicular or rhombic-orbicular, 2–9 cm, (base abruptly narrowed to petiole), margins usually entire, rarely with few scattered teeth, (apex rounded or obtuse, sometimes with apical mucro).

blade oblanceolate, 1.5–5(–7) cm, margins entire or shallowly dentate, (flat).

blade spatulate to oblanceolate, 1–3 cm, margins entire, (apex usually obtuse).

blade elliptic to linear, (0.5–)1–2.5(–3) cm, margins usually entire.

loose, (elongated in fruit).

(secund), dense, (elongated in fruit).

sepals linear-oblong, 4–7.5 mm;

petals spatulate, 6–11 mm.

sepals elliptic or oblong, 4–6(–7) mm, (lateral pair subsaccate, median pair thickened apically, cucullate);

petals (often red or lavender when dried), obovate, 6–8.5(–9.5) mm, (narrowing to broad claw).

valves retaining seeds after dehiscence, pubescent, trichomes appressed;

replum oblong, constricted, 2–3.5 mm, narrower than fruit, apex obtuse;

ovules (2 or) 4 per ovary;

style 4–6(–9) mm.
