basal marcescent, long-petiolate, densely tufted, blade 1-veined, narrowly oblanceolate, 2–10(–20) cm × 2–12(–20) mm, not fleshy, base tapering to petiole, apex acute to obtuse, finely puberulent on both surfaces;

cauline in 1–3 pairs, sessile, much reduced, blade linear-lanceolate, not fleshy.

withering proximally, in whorls of 4, ± sessile to short-petiolate, largest in mid-stem region;

blade lanceolate to ovate-lanceolate, 3–10 cm × 4–40 mm, apex acuminate, puberulent on both surfaces, sparsely so adaxially.

1–5(–7)-flowered, with terminal flower and lateral, open, pedunculate cymes often reduced to single flowers, bracteate;
