several from base, decumbent to ascending, (unbranched), 0.5–1.5 dm.

simple from base, erect, (arising from a condensed rosette), to 1 dm.

(petiole slender);

blade obovate, 3–5 cm (width 10–20 mm, base tapering abruptly to petiole), margins entire, (apex rarely slightly acute).

(ascending or erect);

blade elliptic to oblanceolate to obovate, (usually curled from middle to apex), (1.5–)5–7 cm (width 12–20 mm), margins entire.
