Dioecious shrub or dwarf shrub, single-to several-stemmed, ± erect, cylindrical to rounded, c. 0.3-1.5(-2) m tall. Stems much to sparsely branched above or from the base upwards, branches often regular, paired, ascending to ± divaricate or ± irregular and intricate (if browsed). Leaves strictly decussate, pseudo-verticillate; blades (3-)4-12 x 0.5-2.5(-3) mm, obovate, oblanceolate, lanceolate to linear-lanceolate, glabrous, upper surface often ± shiny, with conspicuous, small epidermis cells; stipular sheath with a small seta. Flowers subsessile or fruiting 9 sometimes with pedicels c. 0.2-1.0(-1.4) mm long, in clusters of many to 2 at nodes, sometimes in ± condensed inflorescence zones; corolla 4-merous, yellow to greenish yellow or pale whitish yellow, occasionally purplish tinged outside, glabrous. cf: tube 0.5-1.2 mm long, (broadly) fiinnel-shaped, lobes 2-3.4 x 0.7-1,2(-1,5) mm; anthers 1.2-2.5 mm long; minute rudimentary ovary with 4 small calyx lobes, tube 0.1-0.4 mm long, lobes 0.3-0.8 x 0.1-0.3 mm; style ±0-0.5 mm long; stigmas 2, (1.5-)2-7.6 mm long; ovary c. 0.9-1.5 x 0.5-0.8 mm, with 4 calyx lobes. Fruit shiny reddish brown to dull greyish brown; mericarps 2.4-4.2 x 1.2-2.2 mm, (broadly) obovate to ± elliptic, distinctly to rather obscurely 3-ribbed (hence mericarps often ± triangular in section), glabrous or, very rarely, shortly hairy, with 2 distinct to obscure ± triangular calyx lobes 0.3-0.6(-0.9) x 0.5-0.7 mm or, less often, calyx lobes ± lacking.
