Flora of North America species comparison

several from base, erect or lateral decumbent, (unbranched), 1–2 dm.

several from base, erect (and stout) or outer ones decumbent, (unbranched or branched, stiff and densely foliate, sterile leaf-bearing branches sometimes present), to 4 dm.

(petiole usually winged);

blade broadly oblanceolate, 3–8 cm, margins usually dentate or pinnatifid, rarely subentire, (terminal lobe acute or obtuse, not rounded).

blade obovate or elliptic, to ca. 3 cm, margins sinuate or shallowly dentate.

blade spatulate to linear-oblanceolate, 1–3 cm, margins usually entire, rarely toothed, (apex acute).

(proximal usually shortly petiolate, distal sessile);

blade obovate to broadly elliptic, 1–3 cm, margins sinuate or shallowly toothed.

loose (and greatly elongated in fruit) to congested.

dense, compact, (elongated in fruit).

sepals linear-oblong, 5–7 mm;

petals spatulate, 9–11 mm.

sepals elliptic or narrowly elliptic or oblong, (3.8–)4.5–5.5 mm, (lateral pair cucullate, very convex, median pair tapering to base, thickened apically, cucullate, often slightly keeled);

petals cuneate, 6.5–8 mm, (slightly expanded at base, margins sinuate, apex retuse or entire).

(recurved), 6–15 mm.

(recurved, curved or sigmoid), somewhat expanded apically.

(usually pendent on arching pedicels, less frequently widely divergent), irregular in shape, (base obtuse or slightly cordate, apex deeply and broadly notched), not strongly inflated, 8–11 × 8–12 mm, (papery);

valves retaining seeds after dehiscence;
