Flora of North America species comparison

several from base, erect to decumbent, (unbranched, stout, densely leafy sterile shoots sometimes present), (0.5–)4–2.5 dm.

few to several from base, erect, (from basal leaf cluster, branched distally, flowering branches slender, subtended by bracts), 3–6 dm.

(clustered at stem base);

blade linear to linear-oblanceolate, 2–5 cm, margins entire, usually involute, sometimes flattened, (apex obtuse to subacute).

blade oblanceolate or broadly obovate, to 10 cm, margins usually sinuate-dentate or entire, sometimes lobed.

blade linear-oblanceolate to linear, 1–3.5(–4.5) cm, margins entire, usually involute.

(proximal shortly petiolate, distal sessile);

blade oblanceolate to narrowly oblong, similar to basal, (distal with base slightly cuneate).

compact, (often nearly subumbellate).

paniculate, (rachises and pedicels more densely pubescent than proximal leaves).

sepals (yellowish or greenish yellow), ovate or oblong, 4.5–7.5(–9) mm, (lateral pair sometimes cucullate, median pair tapering at both ends, thickened apically, cucullate);

petals spatulate or oblong, 6.5–10.5(–15) mm, (base sometimes widened, apex rounded or retuse).

sepals elliptic, 3–7 mm, (median pair slightly thickened apically, cucullate);

petals (white), broadly ovate, to 12 mm, (narrowing gradually to short claw).

(often expanded distally, ascending or recurved, usually straight or slightly curved, rarely nearly sigmoid), 4–15 mm, (stout).

(widely divaricate-ascending and straight, or slightly recurved), 10–15 mm, (slender, pubescent).

(sessile or substipitate), subglobose to slightly ovoid, usually inflated, rarely compressed or obcompressed, 4–6(–10) mm, (apex acute, slightly flattened);

valves sparsely pubescent, trichomes appressed;

ovules (8–)12–16(–20) per ovary;

style (2–)3–4.5(–5.5) mm.

(widely spreading to nearly pendent in age, shortly stipitate), globose or subglobose, not or slightly inflated, 3–10 mm;

valves (not retaining seeds after dehiscence), glabrous;

replum as wide as or wider than fruit;

ovules 8–12 per ovary;

style ca. 2 mm, (slender, fragile).

flattened.
