The name is derived from two Greek words, ἅλς - hals (sea or salt) and ῥάξ - rax (grape-berry). This refers to the first discovered species being found on beaches and having globular fruit.

Of the 28 species, 23 are endemic to Australia and the remainder to the South Pacific (Tuvalu, New Caledonia, New Zealand, the Cook Islands, Rapa Nui and the Juan Fernandez Islands, e.g. H. prostrata (Cook Islands).

Some cultivars are valued as ornamentals, e.g. 'Wanganui Bronze', 'Wellington Bronze'.
