several from base, erect or laterally decumbent, (usually unbranched), (0.3–)0.5–2.5(–4) dm.

blade linear-spatulate, 1.5–4 cm, (base narrowed gradually to petiole), margins entire.

blade linear to somewhat elliptic, 1–4(–8) cm, margins entire or coarsely dentate.

blade spatulate, similar to basal.

(shortly petiolate);

blade usually linear to narrowly oblanceolate, rarely elliptic to rhombic, 0.5–2.5 cm, (base narrowing to petiole), margins entire or remotely dentate (sometimes involute).

crowded in distal 1/3, (4–10-flowered).
