Distribution
editIt is found on Macquarie Island (Australia), and in New Zealand on Stewart Island, Antipodes Island, Auckland Islands and Campbell Island.[4]
Taxonomy
editCarex erebus was first described in 1844 by Francis Boott as Uncinia hookeri in Joseph Hooker's Flora Antarctica.[4][1] In 2015, in order to make the genus Carex monophyletic, the genus, Uncinia, was sunk into Carex.[4] The name, Carex hookeri had already been published in 1837 for another species.[6] Hence a new species epithet was required: erebus was chosen, being the name of the ship (HMS Erebus) on which Hooker sailed on the Antarctic expedition of 1839-1843 when this species was first collected on the Auckland Islands.[4]
Conservation status
editIn both 2009 and 2012 it was deemed to be "At Risk - Naturally Uncommon" under the New Zealand Threat Classification System,[5] and this New Zealand classification was reaffirmed in 2018 (due to its restricted range) but with a further comment that it is secure overseas.[2]
