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.
