Description from Flora of China

Stellaria monosperma (F. N. Williams) Kozhevnikov (1983), not Buchanan-Hamilton ex D. Don (1825); S. williamsiana Kozhevnikov.

Herbs perennial. Roots cylindric, fleshy. Stems branched at base, violet proximally, cylindric, slender, 10--20 cm; nodes and internodes coarsely glandular puberulent or glabrous. Leaves numerous, congested; leaf blade effuse, linear, 5--10 mm, slightly coarsened with ± short, glandular hairs, 1-veined. Cymes terminal, many flowered. Pedicel 5--10 mm, white pubescent. Sepals 5, elliptic, ca. 4 mm, ± papillose spotted abaxially, margin slightly incrassate, sometimes membranous, apex acuminate. Petals 5, white, narrowly obovate, shorter than sepals. Ovary ovoid. Styles 3, linear. Capsule ovoid, equaling persistent sepals, apex 6-lobed. Seed 1, yellow-brown, reniform, reticulate. Fl. and fr. Jun--Oct.

This species may belong to Stellaria . Kozhevnikov (Novosti Sist. Vyssh. Rast. 20: 94–107. 1983) transferred Arenaria monosperma to Stellaria, but published a later homonym.
