few from base, erect, (stout), to 1.5 dm (sometimes greatly reduced).

similar to cauline, (erect, surfaces silvery).

blade suborbicular to rhombic or broadly elliptic, 1–4.5 cm, margins entire, (apex rounded to subacute).

(ascending, subsessile);

blade linear-oblanceolate, (0.6–)0.8–1.3(–1.5) cm, margins entire, (apex acute to narrowly obtuse).

(proximal petiolate, distal subsessile);
