Prostrate densely branching annual herb, with branches to 25 cm. long, glabrous on the undersurface, the upper surface densely pilose with fairly long curved adpressed hairs, the whole plant tinged reddish brown.. Leaves ovate, to 8 × 4 mm., base obliquely subcordate, apex obtuse, margin shallowly toothed, upper surface glabrous, the lower surface with long scattered hairs; petiole 0.5 mm. long; stipules free, linear, to 1.25 mm. long, often deeply 2–3-toothed, pilose.. Cyathia solitary, subsessile, terminal and pseudoaxillary on congested leafy shoots, ± 0.5 × 0.5 mm., with funnel-shaped involucres, pilose; glands 4, minute, subcircular, red, with often almost invisible red appendages; lobes minute, triangular, ciliate.. Male flowers very few (5 or less): bracteoles reduced to 1 or 2 threads; stamens 0.8 mm. long.. Female flower: ovary subsessile; styles 0.6 mm. long, erect, bifid to halfway.. Capsule subsessile (pedicel 0.2 mm. long), splitting the involucre during development, 3-lobed, with truncate base, 1 × 1 mm., pilose with short adpressed hairs.. Seeds conical, sharply 4-angled, 0.6 × 0.4 mm., reddish brown, with shallow transverse ridges and grooves.
Herbs, annual, 10-20 cm tall. Root fibrous. Stems slender and thin, many from base, usually prostrate, 1-2(-3) mm thick, with many adventitious roots, sparsely pilose.

Male flowers few, slightly exserted from involucre. Female flower: pedicel short; ovary shortly pubescent; styles free; stigma 2-lobed. Capsule 3-angular-ovoid, ca. 1.5 × 1.3-1.5 mm, smooth, shortly pubescent. Seeds ovoid-tetragonal, ca. 0.7 × 0.5 mm, dark red, each side with 4 or 5 transverse furrows; caruncle absent. Fl. and fr. Jun-Nov.
