(strongly rosulate);

blade usually oblanceolate or broader, sometimes triangular, 2–3.5 cm (width 5–10 mm), margins entire or with 1 or 2 broad teeth, (apex acute).

(petiole slender);

blade (horizontal on the ground), obovate, 0.5–1.5 cm (width 4–8 mm, base tapering abruptly to petiole), margins entire, (apex usually acute, surfaces silvery from a dense incrustation of appressed, stellate trichomes).
