Pleurophyllum speciosum | |
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. [2] A false colour image is depicted on the lower left corner on the reverse of the current five dollar New Zealand banknote. [3] The Campbell Island daisy was first described by Joseph Dalton Hooker in Flora Antarctica of 1844, [4] 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, [5] and this New Zealand classification was reaffirmed in 2018 (due to its restricted range). [1]

Joseph Dalton Hooker described the species in his 19th century work Flora Antarctica. Plants of this species of forget-me-not are perennial with a prostrate habit, bracteate inflorescences, and white or blue corollas. It is one of two native species of Myosotis in the New Zealand subantarctic islands, the other being M. capitata, which also has blue corollas.

Myosotis capitata is a species of flowering plant in the family Boraginaceae, endemic to the Campbell and Auckland Islands of New Zealand. Joseph Dalton Hooker described the species in his 19th century work Flora Antarctica. Plants of this species of forget-me-not are perennial and erect, and have ebracteate inflorescences and blue corollas. It is one of two native species of Myosotis in the New Zealand subantarctic islands, the other being M. antarctica, which can also have blue corollas.

Megaherbs are a group of herbaceous wildflowers growing in the New Zealand subantarctic islands and on the other subantarctic islands. They are characterised by their great size, with huge leaves and very large and often unusually coloured flowers, which have evolved as an adaptation to the harsh weather conditions on the islands. They suffer from overgrazing due to introduced mammals.
Myosotis antarcticasubsp. antarctica is a subspecies of flowering plant in the family Boraginaceae, native to New Zealand, Campbell Island, and southern Chile. Joseph Dalton Hooker described the species in his 19th century work Flora Antarctica. Plants of this subspecies of forget-me-not are perennial with a prostrate habit, bracteate inflorescences, and white or blue corollas. It is one of two native Myosotis in the New Zealand subantarctic islands, the other being M. capitata, which also has blue corollas.
