several from base, erect or outer ones decumbent, (unbranched, stout, usually sparsely leaved), 1–3 dm.

simple from base, erect, (arising from a condensed rosette), to 1 dm.

blade linear, 2–7(–10) cm, margins entire, repand, or shallowly dentate.

(ascending or erect);

blade elliptic to oblanceolate to obovate, (usually curled from middle to apex), (1.5–)5–7 cm (width 12–20 mm), margins entire.

(sessile);

blade (erect), spatulate to linear, (1–)2–3(–4.5) cm, margins entire, sometimes involute, (apex acute or subacute).

(1–5);

blade oblanceolate, 1–2.5 cm, margins entire.
