sessile;

blades ovate to ovate-elliptic, 1.5 (cauline)–18 (basal) cm, bases shortly sagittate or clasping, margins acerose-denticulate, faces densely glandular-puberulent.

basal, cauline, or both; shortly petiolate or sessile;

blades elliptic-oblong, lanceolate, oblong, oblong-lanceolate, oblong-oblanceolate, orbiculate, ovate, ovate-elliptic, or rhombic-orbiculate (thin and chartaceous to thick and coriaceous), bases cuneate to cordate or clasping, margins entire or lobed or pinnately parted, dentate, or serrate, faces usually minutely stipitate-glandular and/or hirtellous.

obconic to campanulate, 7–9 mm.
