Carpels oblong, 0.7–1 mm. long, contracted or attenuate into a very short style; stigma terminal.
Seeds 2 per carpel, oblong-ovoid, ± 0.5 mm. long, ± 0.3 mm. wide
Petals whitish, yellowish or pink, oblong to oblong-ovate or lanceolate, acute, thickened and somewhat hooded, shortly united at the base.
Calyx-lobes narrowly triangular to lanceolate, 0.7–1.8 mm. long, 0.2–0.3 mm. wide, longer or slightly shorter than the petals, acute to attenuate, shortly united at the base, thin to scarcely fleshy.
Nectary scales broadly to narrowly spathulate.
Stamen-filaments scarcely attached to the corolla-tube, 0.5–0.7 mm. long; anthers ovate, ± 0.1–0.2 mm. long.
Perennial herbs, erect, sprawling or lycopodium-like; stems succulent to almost woody especially at the base, up to 5 mm. in diameter; bark dark brown to reddish brown, peeling irregularly; remains of dead leaves usually present below new growth.
Inflorescence of condensed axillary cymes, shorter than to subequalling or rarely exceeding the subtending leaf; flowers (1–)3–12, (4–)5-merous; pedicels short.
Leaves sessile, lanceolate to ovate, linear or triangular, up to 12 mm. long, up to 3 mm. wide, apex acute or obtuse, sometimes setose, base sometimes spurred, bases of opposite leaves united to form a sheath around the stem up to 2 mm. high, margins thickened and sometimes with marginal papillae; blade flat, thin to thick and fleshy; hydathodes sometimes large and conspicuous.
Follicles 0·75-1 mm. long, contracted or shortly attenuate into a very short style.
Stems ± woody towards the base or herbaceous throughout, 4-gonous above, either slender or somewhat thick throughout or only below, leafy from base to apex or leafless on the older parts.
Moss- or lycopodium-like perennial herbs or sometimes dwarf undershrubs, totally glabrous or sometimes papillose on leaves, calyces and extremities of stem and branches.
Flowers 5-merous, small, shortly pedicellate, in ± dense axillary fascicles shorter than to equalling or a little exceeding the subtending leaf, sometimes flowers solitary.
Leaves not to ± succulent, soft to ± rigid, ovate to linear, obtuse or acute, sometimes setose at the apex, sessile, connate at the base into a short sheath, slightly thickened and indexed at the margin, ± canaliculate above towards the apex, the apical ones ± dense.
Corolla whitish, yellowish or rose, turning reddish-brown on drying; petals oblong or ovate-oblong, connate at base up to 0·5 mm., folded upwards and appearing cuspidate there.
Calyx slightly shorter or longer than the corolla or subequalling it; sepals lanceolate, acute to rather attenuate and nearly subulate, thin to somewhat thick, nearly hyaline to whitish or pale green, shortly connate at the base.
