Pleurophyllum speciosum, also known as the giant emperor daisy or Campbell Island daisy, is a megaherb native to the Auckland and Campbell Islands of New Zealand.[1] A false colour image is depicted on the lower left corner on the reverse of the current five dollar New Zealand banknote.[2] The Campbell Island daisy was first described by Joseph Dalton Hooker in Flora Antarctica of 1844,[3] after he had collected it during the Ross expedition.
In both 2009 and 2012 it was deemed to be "At Risk - Naturally Uncommon" under the New Zealand Threat Classification System, and this New Zealand classification was reaffirmed in 2018 (due to its restricted range).
