few from base, well-exserted from basal leaves, 0.4–1(–1.2) dm.

blade suborbicular to narrowly or broadly oblanceolate to broadly elliptic or rhombic, (1.2–)2–6(–8) cm, (base usually abruptly narrowed to petiole), margins entire, sinuate, or lobed.

blade (erect), obovate to orbicular, 1.5–2.5 cm, (base evidently distinct from petiole), margins entire, (folded).

(proximal petiolate, distal sessile);

blade obovate or elliptic to spatulate, 0.5–2 cm, margins entire.

blade spatulate, margins entire.

(usually not secund), dense, (sometimes elongated in fruit).
