About

Libertia micrantha, commonly known as mikoikoi and the native iris, is a species of flowering plant in the family Iridaceae. It is endemic to New Zealand; its range covers the North and South Islands. A perennial herb, L. micrantha inhabits montane forests in high rainfall areas and river banks. It was first described in 1837 by the British botanist Allan Cunningham. The specific epithet, micrantha, simply means 'tiny flower'.

Where it grows

Libertia micrantha is endemic to New Zealand. Its range covers the North and South Islands. In the North Island, the species is widespread on mountain ranges from Mangōnui (in Northland) to Wellington. In the South Island, the species primarily occurs in the western side of the island, from Nelson and Marlborough to Fiordland. It does not naturally occur on Stewart Island, and appears to be uncommon in the eastern side of the South Island. L. micrantha's 2023 assessment in the New Zealand Threat Classification System was "Not Threatened".
