Characteristics

Dwarf shrub, 'bisexual' or 'female' (always?), procumbent and ± straggling, sometimes cushion-forming. Stems c. (100-)150-300(-400) mm long, ± sparsely to much branched, mostly densely leafy. Leaves decussate, pseudoverticillate; blades often curved, (5-)8-12 x (0.3-)0.5-0.8(-1) mm, linear to linear-lanceolate, often seemingly terete and needle-like when dried due to strongly revolute margins, glabrous, midrib below (and sometimes also upper surface) reddish brown; petioles subobsolete; stipular sheath mostly with a seta to 0.6(-1) mm long. Flowers subsessile, in clusters of 2-6 at nodes; corolla 4-merous, yellowish, often with a few short hairs near tip 'bisexual': tube 1-1.3 mm long, narrowly funnel-shaped, lobes (1.3-)1.5-2.5(-3) x 1 mm; anthers 1.3-2 mm long; style 0; stigmas 2, 3-5 mm long; ovary c. 0.8-1.2 x 1 mm, with 10 cm distinct calyx lobes. 'Female': tube c. 0.3-0.5 mm long, lobes 0.2-0.5 x 0.2 mm; gynoecium as in 'bisexual'. Fruit reddish brown, ± heart-shaped in side view; mericarps 2-2.5 x (1-)1.2-1.5 mm, ovate to obovate, ± sparsely covered with curled whitish hairs c. 0.1-0.2 mm long, sometimes with 51 mm distinct ± triangular calyx lobes c. 0.1-0.2 mm long.
