cauline in 1–3 pairs, ± sessile, reduced, blade narrowly oblanceolate to linear-lanceolate, 0.7–2 cm × 1–3 mm, apex acute, puberulent.

sessile, or basal with short pseudopetiole;

blade linear to lanceolate or broadly ovate, base round to cuneate, apex acute to shortly acuminate, puberulent on both surfaces, sometimes glandular.
