Shoots strongly angular, with scattered glandular hairs. Lvs subsessile, 1-2.7 × 2-4 mm, linear or oblong-linear, entire; base attenuate; apex obtuse or nearly so. ♂ fls in continuous or interrupted terminal spikes or panicles. ♀ fls solitary or few in axillary clusters, monomorphic; bracteoles united for c. ⅓ length, to 3.5 × 3.5 mm at fruiting, often smaller, broad-ovate to rhombic, entire; united part becoming indurate; free parts becoming ± swollen, spongy; apex obtuse. Seed c. 2 mm diam., circular, with radicles protruding.
A dense small shrub. It grows 60-90 cm high. It can be 2 m high. It can spread 1.8-6 m wide. Stems can form roots at the nodes. The leaves are pale grey-blue.
