petiole (5–)8–25(–32) cm;

lateral leaflets (when present) petiolulate to subsessile, blade similar to terminal, sometimes smaller;

terminal leaflet (petiolule (0.7–)2–5(–11) cm), blade (of simple leaf) ovate to orbicular to broadly cordate or reniform, (1.5–)2.5–7.5(–10) cm × (12–)20–90(–130) mm, base obtuse to cordate, margins entire or dentate to shallowly sinuate, (often with apiculae at veins ending at margin, sometimes minutely pubescent on veins).

2–5, usually 3 (or 5)-foliolate, rarely simple, petiolate, leaflets petiolulate or sessile;

petiole 1–5(–9) cm, base not auriculate;

lateral leaflets sessile, blade similar to terminal, smaller, margins usually dentate, rarely entire;

terminal leaflet sessile or petiolulate, blade usually broadly ovate to suborbicular or lanceolate, rarely narrowly oblong, 1–7 cm × (5–)10–47(–65) mm.

(corymbose or paniculate, bracteate in C. pattersonii), elongated in fruit.

ebracteate.

sepals (caducous), usually erect, rarely spreading or ascending, ovate or oblong, lateral pair saccate or not basally, (usually glabrous, rarely pubescent);

petals (rarely absent), white, pink, purple, or lilac, obovate, spatulate, or oblanceolate, claw absent or strongly differentiated from blade, (apex obtuse, rounded, emarginate, or subemarginate);

stamens (6, rarely 4), equal in length;

filaments not dilated basally;

anthers ovate, oblong, or linear, (apex obtuse), glabrous [rarely pubescent];

nectar glands confluent, lateral glands annular or semiannular, subtending bases of stamens, median glands present (2, rarely 4) or absent.

sepals (erect to ascending), oblong, 3.5–4.5(–5.5) × 1.5–2(–2.5) mm, lateral pair saccate basally;

petals white to pale rose, often broadly obovate, 8–13(–15) × 4–8 mm (clawed, apex rounded);

filaments: median pairs 4–6.5 mm, lateral pair 3–4 mm;

anthers oblong, 1.2–1.7 mm.

erect, ascending, divaricate, or reflexed, slender or stout.

ascending to divaricate, 10–33(–41) mm.

siliques, sessile, usually linear, rarely narrowly oblong or narrowly lanceolate, smooth or torulose, latiseptate;

valves (papery, elastically dehiscent, becoming spirally or circinately coiled) each not veined, glabrous or, rarely, pubescent;

replum strongly flattened;

septum complete, (membranous);

ovules 4–80 per ovary;

style usually distinct, rarely obsolete;

stigma capitate.

linear, 2.2–5.4(–6) cm × 2–3 mm;

ovules 12–22 per ovary;

style 2–5(–6) mm.

uniseriate, flattened, usually not winged, rarely margined or winged, oblong, ovoid, or globose;

seed coat (smooth, minutely reticulate, colliculate, or rugose) mucilaginous or not when wetted;

cotyledons accumbent, rarely incumbent.
