Dwarf shrub or subshrub with basally woody stems, dioecious (very seldom 'male' with odd 'bisexual'), prostrate, often with ± thick, woody tap root. Stems trailing, rooting at nodes, to c. 1 m long, with ascending to ± erect short lateral branches, c. 10-50(-100) mm long. Leaves decussate, pseudoverticillate; blades (5-)7.5-12 x 0.7-2(-2.3) mm, lanceolate, oblanceolate to ± linear-lanceolate, glabrous or (lower half of) margins papillate; petioles subobsolete; stipular sheath mostly with a small ± broadly triangular seta. Flowers subsessile, on short lateral branches, single or paired at nodes (seldom in paired 3-flowered cymes); corolla 4-merous (very seldom also 5-merous in 'male'), yellowish to greenish yellow, frequently tinged reddish purplish outside, glabrous. 'Male' (odd 'bisexual'): tube 1.2-2.3 mm long, narrowly funnel-shaped, lobes (2-)2.4-3(-3.7) x 0.7-1 mm; anthers 1.5-2.2 mm long; 'male': small rudimentary ovary present. 'Female': tube (0.5-)0.7-0.9(-1.1) mm long, lobes 0.5-1 x 0.1-0.2 mm; style 0-1.3 mm long; stigmas 2, 4.8-10 mm long(shorter in odd 'bisexual'); ovary 0.7-1.4 x 0.5-1 mm, not crowned by conspicuous calyx lobes. Fruit reddish (brown), shiny; mericarps (2-)2.3-2.9 x 1.2-1.7 mm, (ob)ovate, glabrous or with very short whitish hairs, not crowned by distinct calyx lobes.
