Herb, annual or perennial, with stem and branches prostrate to ascending, 10–40 cm long, with conspicuous indumentum of stellate hairs. Cauline leaves barely petiolate or with stellate-hairy petioles to c. 1 cm long; lamina mostly very widely obovate to obovate, 8–23 mm long, 7–14 mm wide, margin entire, both surfaces greyish green and with a moderate to dense indumentum of stellate hairs, upper surface sometimes glabrescent (Walsh 1996: 227). Flowers c. 3–8 in axillary clusters, near-sessile or on stellate-hairy pedicels to c. 5 mm long. Perianth segments 6–7 mm long, externally stellate-hairy but internally glabrous, with 1 or 2 segments thin and entirely herbaceous, and other segments with scarious margins. Stamens c. 10–15; some staminodes also present. Ovary glabrous. Styles 5, 1–1.5 mm long. Capsule 4.5–6 mm long, 5-valved, 4–6 mm long, enclosed within the perianth. Seeds subreniform, c. 0.4 mm long, shiny reddish brown, with lines of tubercles.
A semi-erect, decumbent or prostrate and rosette-forming pale-or grey-green diffusely-branched densely stellate pubescent herb up to 20 cm. high; branchlets 10–45 cm. long.. Leaves opposite or apparently verticillate, petiolate, 10–42 mm. long (including petiole of 1–11 mm.), 5–22 mm. broad; blade elliptic or obovate or suborbicular, plane or the veins impressed above and prominent below, entire or the margin obscurely wavy, subacute to rounded at the apex, cuneate at the base..

Stamens 10-20 or more, rarely 3-5, the outer often without anthers. Stigmas 3 or 5. Seeds dark brown, smooth or with raised ridges, with or without tubercles, the aril about half the length of the seed.

Flowers several, in groups, sessile or subsessile. Tepals elliptic or oblong, 4-6(-10) mm. Stamens usually 3-15, free. Ovary ovoid, 5-loculed; styles 5, free, linear, short, curved outward. Capsule ovoid, ca. as long as persistent tepals, 5-valved. Seeds numerous, chestnut-brown, reniform, granulose; strophiole scrotiform, ca. 2/3 as long as seed or longer. Fl. and fr. spring-summer. 2n = 36.
Stems 0.5-3.5 dm. Leaves whor-led; petiole 1-7 mm; blade obovate or orbiculate to broadly spatulate, 5-25 × 0.4-17 mm, base cuneate, apex broadly rounded to acute. Flowers in clusters of 3-15; sepals lanceolate, 3.5-4.1 × 0.4-2 mm, stellate-pubescent abaxially, glabrous adaxially, apex rounded to acute or slightly mucronate; stamens 3-5. Capsules ellipsoid, 3.6-4.5 × 1.8-2 mm. Seeds 10-25 per locule, orange-brown, 0.4-0.6 × 0.3-0.4 mm, papillate, somewhat glossy or dull; papillae sometimes black. 2n = 36.
Much-branched, prostrate annual, stems 150-500 mm long, covered with stellate and simple hairs. Leaves alternate below, with upper ones in whorls, narrowly elliptic to ovate, ± fleshy, without stipules. Flowers 1 or 3-8 axillary cymes, sepals with acute mucronate tips, yellowish to whitish green on inside, inner 3 with membranous edges, stamens 10-20 or more.
A herb. It lays along the ground. The stem are hairy. They are 10-40 cm long. There are many branches. The leaves at the base are in a ring. These dry off. The higher leaves are 6-24 mm long by 5-15 mm wide. Several flowers occur in a group. The fruit are capsules which have 5 valves. There are many chestnut brown seeds. They are kidney shaped.
Leaves alternate, opposite or apparently verticillate; laminae 2–37 × 4–23 mm., elliptic, obovate, spathulate or circular, entire; base cuneate, apex subacute to rounded; petiole up to 1–3 cm. long, green when glabrous or glabrescent, whitish when densely covered with persistent stellate silky hairs.
