Etymology: Saltbush is a plain compound: "salt" joined to "bush," the familiar word for a low, branching shrub. The name describes exactly what the plant does. Many saltbushes, the Atriplex species of Australia and the arid regions of the wider world, grow in soils so saline that most plants could not survive there, and they take up and store salt in their tissues. The name thus records an adaptation rather than a shape or a colour. The word is "bush" in its ordinary sense, a dense woody plant without a single main trunk, and "salt" in its literal sense of sodium chloride. Put together, the compound reads simply as "salt-loving bush" or "bush of salty ground," which is a transparent and accurate name for a plant that thrives where the soil is salty.
