Olearia lyallii

Olearia lyallii is a New Zealand plant from the genus Olearia. It is commonly known as the subantarctic tree daisy. The species is endemic to the Snares Islands and southern New Zealand, and has also established itself as an introduced species on the Auckland Islands, where the type specimen was described from.[1] O. lyallii forms trees up to 10 m tall with trunks 50 cm in diameter.[2]

Auckland Islands

The Auckland Islands (Māori: Motu Maha or Maungahuka) are an archipelago of New Zealand, lying 465 kilometres (290 mi) south of the South Island. The main Auckland Island, occupying 510 km2 (200 sq mi), is surrounded by smaller Adams Island, Enderby Island, Disappointment Island, Ewing Island, Rose Island, Dundas Island, and Green Island, with a combined area of 625 km2 (240 sq mi). The islands have no permanent human inhabitants.

The islands are listed with the New Zealand Outlying Islands. The islands are an immediate part of New Zealand, but not part of any region or district, but instead Area Outside Territorial Authority, like all the other outlying islands except the Solander Islands.

Ecologically, the Auckland Islands form part of the Antipodes Subantarctic Islands tundra ecoregion. Along with other New Zealand Sub-Antarctic Islands, they were designated a UNESCO World Heritage Site in 1998.

Brachyglottis stewartiae

Brachyglottis stewartiae is a species of flowering plant, often referred to as a tree daisy, in the Asteraceae family. It is found only in New Zealand, especially on its subantarctic islands. With another tree daisy, Olearia lyallii, it is common in the forest of the Snares Islands, growing to about 6 m in height. It bears conspicuous clusters of yellow daisy-like flowers.

Izatha oleariae

Izatha oleariae is a species of moth in the family Oecophoridae. It is endemic to New Zealand. This species is classified as "At Risk, Naturally Uncommon" by the Department of Conservation. It is only found on the Snares Islands.

List of trees native to New Zealand

New Zealand's long geological isolation means that most of its flora is unique, with many durable hard woods. There is a wide variety of native trees, adapted to all the various micro-climates in New Zealand. The native bush (forest) ranges from the subtropical kauri forests of the northern North Island, temperate rainforests of the West Coast, the alpine forests of the Southern Alps and Fiordland to the coastal forests of the Abel Tasman National Park and the Catlins.

In the early period of British colonisation, many New Zealand trees were known by names derived from the names of unrelated European trees, but more recently the trend has been to adopt the native Māori language names into English. For a listing in order of Māori name, with species names for most, see the Flora of New Zealand list of vernacular names.

The New Zealand Plant Conservation Network has published a list of New Zealand indigenous vascular plants including all 574 native trees and shrubs. This list also identifies which trees are endemic to New Zealand and which are threatened with extinction.


Olearia is a genus of flowering plants belonging to the family Asteraceae. There are about 130 different species within the genus found mostly in Australia, New Guinea and New Zealand. The genus includes herbaceous plants, shrubs and small trees. The latter are unusual among the Asteraceae and are called tree daisies in New Zealand. Shrubs are called daisy bushes. All bear the familiar daisy-like composite flowerheads.

The genus is named after Johann Gottfried Olearius, a 17th-century German scholar and author of Specimen Florae Hallensis. Originally a large genus, a molecular study has found it to be polyphyletic.Olearia species are used as food plants by the larvae of some Lepidoptera species including Aenetus ligniveren, which burrows into the trunk.

Stigmella laqueorum

Stigmella laqueorum is a species of moth in the Nepticulidae family. It is endemic to New Zealand. This species is classified as "At Risk, Naturally Uncommon" by the Department of Conservation.
