simple or few to several from base, erect, (unbranched, slender), 0.2–1(–1.5) dm.

blade narrowly oblanceolate or broadly elliptic, 1–7(–12) cm, margins entire or shallowly toothed, sometimes repand, (inner blades usually flattened in age, surfaces often gray-green, scabrous).

(densely tufted, not rosulate, reflexed in age);

blade obovate to oblanceolate, 0.7–2(–3) cm, margins usually entire, sometimes repand or shallowly dentate, (apex acute).

(usually secund);

blade spatulate or obovate, 1–2.5(–4.5) cm, margins entire or shallowly toothed, (flat or involute).

similar to basal, becoming narrower distally, somewhat reflexed, (distal) blade linear or narrowly oblanceolate, 0.5–2.5(–5.5) cm.

somewhat crowded (to moderately elongated in fruit, exceeding basal leaves).

dense, often subcorymbiform.

sepals broadly elliptic or oblong, 4–7.5(–9) mm, (median pair thickened apically, cucullate);

petals cuneate or obovate, 7–10(–16) mm, (tapering gradually to broad claw).
