erect, branched, rarely simple, 15–45 cm, with long, often crinkled hairs mixed with short pubescence, viscid-glandular distally.

several, simple or branched, spreading to ascending, leafy, 10–30 cm, densely pubescent, glandular.

2 per node, blade with coarse, ascending, scabrous pubescence on both surfaces;

basal few, withering, blade oblanceolate to spatulate-petiolate, 0.5–5 cm × 3–15 mm;

cauline blades oblanceolate to lanceolate, 1–7 cm × 1–15 mm, apex obtuse or shortly acuminate to acute.
