Prostrate to decumbent perennial, monoecious. Leaves very shortly petiolate, elliptic to circular, 2–6 mm long with a scaly sheen on both surfaces. Flowers in glomerules; male glomerules terminal or in distal leaf axils on principal branchlets; female glomerules scattered along branches or on dwarf lateral shoots, sometimes reduced to one flower. Fruiting bracteoles broadly oblong-elliptic, convex, obtuse or rounded at apex, 1–1.5 mm long, sessile or minutely stipitate, the valves united except at apex.
