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.

several from base, erect or outer usually decumbent toward base, (from below a terminal tuft of mostly erect leaves, unbranched), 1–2 dm.

(clustered at stem base);

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

blade ovate to elliptic, 2–4 cm, (base gradually narrowed to petiole), margins entire, (surfaces densely pubescent with trichome layers).

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

(remote, proximal shortly petiolate);

blade spatulate to oblanceolate, similar to basal, (base often cuneate), margins entire.

compact, (often nearly subumbellate).

elongated.

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);

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

(recurved), 7–10 mm.

(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.
