Abstract
Atriplex cinerea (Chenopodiaceae), a common coastal Australian salt bush, has been treated as adventive to New Zealand since 1940. Evidence is presented which refutes this claim and reinstates A. cinerea as indigenous to New Zealand. A detailed description and chromosome count (based on New Zealand material) for A. cinerea is provided, and a lectotype is selected for the species. Aspects of the ecology, means of seed dispersal, and the conservation of the species are reviewed. It is concluded that A. cinerea is a further example of a distinctive vagrant element within the indigenous flora of New Zealand.
