Flora of North America species comparison

several from base, erect to decumbent or prostrate, (unbranched or branched, sometimes densely leaved), 1–3.5(–4.5) dm.

simple from base, erect, (arising from a condensed rosette), to 1 dm.

blade obovate to broadly oblong, 1.5–5(–8) cm, margins lyrate-pinnatifid, dentate, or entire.

(ascending or erect);

blade elliptic to oblanceolate to obovate, (usually curled from middle to apex), (1.5–)5–7 cm (width 12–20 mm), margins entire.

(proximal sometimes petiolate, distal sessile);

blade linear to oblanceolate, often falcate, 1–4(–7) cm, (proximal with base sometimes cuneate), margins entire, repand, or shallowly dentate.

(1–5);

blade oblanceolate, 1–2.5 cm, margins entire.

dense.

compact (or elongated in fruit, to 1 dm, barely exceeding leaves).

sepals elliptic or oblong, 3–6.5 mm, (lateral pair subsaccate, median pair thickened apically, cucullate);

petals (widely spreading at anthesis, yellow to orange, claw sometimes whitish), cuneate, obdeltate, or obovate, (tapering to claw), 5–8(–10) mm, (claw often widened at base).

sepals (erect), oblong to linear or spatulate, 5.5–7 mm;

petals spatulate, 10–14 mm, (claw undifferentiated from blade).
