Petiole (1–)2–5 mm long, hairy along margins. Inflorescences terminal and lateral, reduced spikes arranged (often somewhat laxly) in a terminal flowering head (0.5–)1–3(–4.3) cm long; lowermost pair of bracts on a spike opposite and connate, or rarely free, then subopposite or alternate above, lanceolate to linear or sometimes deltoid, usually subacute or obtuse, glabrous or minutely ciliolate, and sometimes also sparsely hairy inside; pedicels absent. Flowers on individual plants either hermaphrodite or female. Calyx 4.5–7(–9) mm long, usually linear to linearlanceolate or rarely oblong or deltoid, subacute to obtuse or occasionally acute, minutely ciliolate, glandular hairy inside, margins green or red (at apex). Corolla white; tube (2.5–)4.0–6.0 mm long, shorter than or equalling or sometimes longer than calyx; lobes usually shorter than corolla tube, glabrous; lobes usually ovate to elliptic, subacute to obtuse, patent to recurved (with age), with apex turned slightly upwards. Anthers held at corolla throat, pink, 1–1.9 mm long; sterile anthers white. Ovary glabrous; style 3–8 mm long (on hermaphrodite flowers), or 5–6 mm (on female flowers); stigma no wider than style (usually in hermaphrodite flowers) to subcapitate (usually in female flowers). Capsules acute to subacute, 3.5–4.5(–5.5) mm long, 2–3.5 mm wide, glabrous.

Mat-forming subshrub to 20 cm tall, 1 m diameter. Leaves not distinctly keeled, spathulate, 9–16 mm long, (2.5–)3.5–9 mm wide; apex rounded to slightly retuse; margins green or colourless, smoothly cartilaginous, entire. Calyx lobes green, linear, 5–9 mm long.

Subshrub to 20 cm high. Leaves often slightly keeled, elliptic or rhomboidal to spathulate, 6.5–11(–13.5) mm long, (2–)3–7.5(–8.5) mm wide; apex obtuse; margins usually red near shoot apex, slightly papillate, or rounded and/or minutely erose, occasionally obscurely toothed. Calyx lobes red at apex, oblong to linear, 4.5–7 mm long.

Subshrub, to 20 cm tall, forming mats up to 30 cm in diam. Branches prostrate or decumbent; internodes 0.9–5(–7.5) mm long. Leaves decussate to subdistichous, shortly connate, usually petiolate (unless lamina very narrow), erecto-patent to recurved, green to dark green; leaf bases shortly connate; lamina elliptic to obovate or oblong, often quite narrow, somewhat fleshy, 3.5–7.5(–9.5) mm long, (1.5–)2.0–5.5 mm wide; apex subacute to rounded, and often distinctly “dimpled”; leaf margin not thickened, often red, midrib very slightly thickened beneath, margin commonly ciliate toward base sometimes with minute glandular hairs along margin, usually entire or rarely minutely erose or shallowly toothed. Inflorescences terminal, simple, usually pedunculate (and sometimes also subtended by 2–4 lateral pedunculate spikes), or sometimes with numerous bracts at base containing aborted flower buds, 0.8–2 cm long, peduncle 0.15–0.4 cm long; bracts usually opposite, or lowermost pair opposite then subopposite or alternate above, connate or free; pedicels absent.
