blade pandurate or obovate, 3–6 cm, margins usually deeply and broadly incised, rarely subentire, (apex obtuse).

blade suborbicular, (1–)2.5(–3) cm, (base abruptly narrowed to petiole), margins entire, (flat), (surfaces densely silvery pubescent, trichomes in multiple layers, appressed).

blade oblanceolate to spatulate, similar to basal, (3–6 mm wide), margins entire, (apex often somewhat acute).
