several from base, decumbent to erect or ascending (unbranched), 1–2.5 dm.

several from base, erect or laterally decumbent, (usually unbranched), (0.3–)0.5–2.5(–4) dm.

(outer ones spreading, inner erect or ascending);

blade ovate, often broadly so, 4–7 cm, margins repand to lyrate-lobed.

blade linear to somewhat elliptic, 1–4(–8) cm, margins entire or coarsely dentate.

similar to basal, blade oblanceolate or narrowly oblong, reduced in size, (base gibbous).

(shortly petiolate);

blade usually linear to narrowly oblanceolate, rarely elliptic to rhombic, 0.5–2.5 cm, (base narrowing to petiole), margins entire or remotely dentate (sometimes involute).

loose, (elongated).

loose to somewhat dense.

sepals lanceolate or narrowly oblong, 5.8–7.2 mm;

petals (erect, sometime purplish or drying purple), narrowly oblong to oblanceolate, 7–10 mm, (not or weakly clawed).

valves (retaining seeds after dehiscence), pubescent, trichomes ascending, appearing fuzzy;

replum oblong to oblanceolate, as wide as or wider than fruit, apex obtuse;

ovules 4 per ovary;

style (4–)5–7 mm.

globose, broadly ellipsoid, or ovoid, not or slightly inflated, 5–8 mm, (firm, apex usually acute);
