simple or few from base, decumbent to ascending, (arising laterally from a tight hemispherical tuft of leaves), to 0.15 dm.

several from base, erect (and stout) or outer ones decumbent, (unbranched or branched, stiff and densely foliate, sterile leaf-bearing branches sometimes present), to 4 dm.

similar to cauline, (erect, surfaces silvery).

blade obovate or elliptic, to ca. 3 cm, margins sinuate or shallowly dentate.

(ascending, subsessile);

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

(proximal usually shortly petiolate, distal sessile);
