distal winged-petiolate or subpetiolate or sessile, blades lance-ovate or narrowly ovate to lanceolate or sometimes linear (in arrays), 7–1.5 × 3–31 mm, gradually and strongly reduced distally, bases cuneate, scarcely or not clasping, to slightly rounded and ± clasping, margins serrulate or entire, apices acute to acuminate.

bluish (green) thin, sometimes ± fleshy, margins usually entire, sometimes serrulate, strigoso-ciliate to scabrous, midribs conspicuous, apices acute to short-acuminate, faces glabrous;

basal withering by flowering, petiolate, blades spatulate, 15–205 × 1.5–9 mm, bases attenuate;

proximal cauline usually withering by flowering (with clusters of smaller leaves in axils, often elongating into branches);

cauline sessile, blades linear-oblanceolate, (10–)30–80(–150) × 1–4(–9) mm, gradually reduced distally, bases slightly dilated and clasping to rounded.
