few to several from base, prostrate to decumbent or erect, 0.5–2(–4) dm.

several from base, ± erect, exceeding basal rosette by ± 0.5 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.

(forming a strong rosette; long-petiolate);

blade oblanceolate to ovate or orbicular, (1.5–)2–4(–8) cm, (base usually abruptly tapering to petiole), margins entire.

(proximal petiolate, distal sessile);

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

blade oblanceolate, 1–2 cm, margin entire, (apex acute).

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

congested, (greatly exceeding leaves).

sepals lanceolate, 4–6(–7) mm;
