Prostrate villous annual; stems numerous, 2-30 cm long; leaves on petioles from longer than to as long as the leaflets; leaflets obovate to broadly obcordate, 4-20 mm long, irregularly and faintly denticulate; stipules herbaceous, broadly ovate, with an acute point.
Flowers of two kinds, the 2-5 outer complete and fertile, but all later-formed inner flowers of the head reduced to solid calyces, the rigid recurved lobes of which act as anchors in securing ripened pods in the soil; heads on peduncles usually elongated to longer than the petioles, at first erect, later turning the head down into the earth after anthesis; fertile calyx 3-4 mm long, slender, glabrous or sparsely hairy, sometimes reddish; lobes equal, setaceous, hairy and longer than the tube; corolla 8-14 mm, whitish.
Pod ovoid, somewhat exserted, crustaceous, 1-seeded; seed obliquely ovoid, 2.5-3.5 mm long, blackish, smooth.
