General description

Silver saltbush is an open, many-branched shrub growing to about 1.5m. The branches are rigid and slender. The leaves are about 10mm long and are generally elliptical with a smooth outline. They have a thin, bluish, scaly covering.

There are separate male and female plants. The male flowers occur in small, globular clusters. The female flowers occur in clusters at the ends of the branches and along the stems. At maturity, thin, papery seed cases resemble two leaves joined together and they may have two little antler-like structures on each side near the base. Each seed case contains a single seed.
