erect or decumbent at base, branched, to 100 cm, finely hirsute, glandular-puberulent distally.

mostly basal, densely tufted;

basal numerous, pseudopetiolate, blade narrowly oblanceolate, tapering into base, 0.5–3 cm × 1.5–4 mm, ± fleshy, apex acute, puberulent;

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

blade hirsute on both surfaces;
