several, erect, not much-branched, slender, 15–60 cm, flowering above middle.

basal with blade 1-veined, oblanceolate, broadly spatulate, 1–4 cm × 2–8 mm, apex obtuse to acute, glandular-puberulent throughout, rarely subglabrous adaxially;

cauline in 3–6 pairs, sessile, reduced distally, blade lanceolate, narrowly elliptic, or oblanceolate, 2–4 cm × 2–8 mm, apex ± acute, glandular-puberulent throughout.

cauline in 2–4 pairs, gradually reduced distally, blade linear with broadened base, 1–8 cm × 1–2 mm, apex acute;
