Leaves sessile, spreading to erect, sometimes glaucous; lamina (main stem) 3–30(–37) × 1–4 mm, linear, apex obtuse or apiculate to acute, margin revolute, base cuneate, 1-veined or with 1–3 pairs of lateral branches from lower 2/ 3 of midrib, with laminar glands pale, numerous, small, marginal glands pale, dense; leaves(axillary and sterile shoots) smaller, ± crowded. Inflorescence (1)3–∞-flowered, narrowly pyramidal to cylindric, (15–)50– 120 mm long, with lateral cymules 1–2(–4)-flowered, rarely with one pair of lower branches; bracts and bracteoles lanceolate to linear, entire, upper sometimes with marginal black glands.
