Leaves decussate, pseudo-verticillate; blades (4)6–12(22) x (0.5)0.8–1.5(2) mm., linear, linear-(ob-)lanceolate or narrowly lanceolate, ± membranous; flat to somewhat revolute margins mostly papillate, midrib below often reddish-brown and prominent; petioles subobsolete; stipular sheath with 1 (rarely 3) small seta(e). Flowers subsessile, in clusters of 6–2 (occasionally more) at nodes; corolla 4-merous, greenish to yellowish, often papillate near tip. Hermaphrodite, male: tube (0.5)0.7–1.4(1.7) mm. long, narrowly funnel-shaped, lobes 1.2–1.9(2.5) x 0.3–0.7 mm.; anthers 1–1.8(2) mm. long; hermaphrodite: stigmas often shorter than in female; ovary 0.5–0.9 x 0.3–0.8 mm., with 4 ± indistinct calyx lobes.
