basal and proximal cauline with petiole 1–2 mm;

blade elliptic to elliptic-obovate, 8–20(–30) × 2.5–8(–15) cm, base subrounded to broadly cuneate;

cauline not clasping, gradually smaller distally, base not decurrent, margins coarsely crenate to crenulate, apex of distal cauline and floral bracts acute to obtuse.
