Flora of North America species comparison

erect or decumbent, unbranched or branched distally.

usually several from caudex, rarely simple, erect to decumbent, unbranched or branched distally, (1–)1.3–4(–5) dm, densely pubescent throughout or glabrescent distally.

basal and cauline;

petiolate or sessile;

basal usually rosulate, petiolate, blade margins entire, dentate, or lyrate-pinnatifid, (apex obtuse to acute);

cauline sessile, blade (base attenuate, not auriculate), margins entire, subentire, dentate, or pinnatifid.

rosulate;

petiole 0.5–2.5 cm;

blade narrowly to broadly oblanceolate, 2–5 cm × 5–15 mm, margins lyrate-pinnatifid to coarsely dentate, apex obtuse to acute, surfaces densely pubescent.

4–12;

blade oblong to oblanceolate, 0.6–2 cm × 2–6 mm (base attenuate, not auriculate), margins coarsely dentate to pinnatifid, or (distal) subentire or dentate, apex obtuse to subacute, surfaces densely to sparsely pubescent.

(corymbose, several-flowered), considerably elongated in fruit.

sepals (erect), oblong;

petals white, oblanceolate-spatulate, (longer than sepals, claw obscurely differentiated from blade, apex rounded);

stamens slightly tetradynamous;

filaments not dilated basally, (slender);

anthers ovate or oblong, (apex obtuse);

nectar glands confluent, subtending bases of stamens.

sepals 1.5–2 × 0.8–1.2 mm;

petals (3–)4–7 × 1.2–2 mm;

filaments 2–3 mm;

anthers ovate, 0.5–0.6 mm.

ascending to subdivaricate, (straight), slender, (terete).

4–15 mm, densely pubescent to glabrescent.

subsessile or shortly stipitate (gynophore less than 1 mm), linear, slightly to strongly torulose, subterete to strongly latiseptate;

valves each without midvein or with obscure one on proximal 1/2, sparsely to densely pubescent or glabrescent;

replum rounded;

septum complete;

ovules 12–30 per ovary; (style obsolete or distinct);

stigma capitate.

ascending to suberect, straight to slightly tortuous, strongly torulose, strongly latiseptate, (1–)1.5–2(–2.5) cm × 0.8–1 mm;

valves each with obscure midvein, densely pubescent to glabrescent;

ovules 12–20 per ovary;

style 0.2–1.3 mm.

uniseriate, plump, not winged, oblong;

seed coat (minutely reticulate), not mucilaginous when wetted;

cotyledons incumbent.

1–1.3 × 0.5–0.6 mm.
