simple or few to several from base, prostrate, (from below a terminal rosette of leaves, unbranched), 0.2–0.5 dm.

blade elliptic or obovate to oblong, 4–15 cm, margins entire, dentate, or lyrate-pinnatifid.

blade elliptic to broadly ovate or obovate, (1–)1.5–2.5(–3) cm, margins entire, (apex obtuse).
