<i>Metrosideros excelsa</i> Species of tree

Metrosideros excelsa, with common names pōhutukawa, pohutukawa, New Zealand Christmas tree, New Zealand Christmas bush, and iron tree, is a coastal evergreen tree in the myrtle family, Myrtaceae, that produces a brilliant display of red flowers made up of a mass of stamens. The pōhutukawa is one of twelve Metrosideros species endemic to New Zealand. Renowned for its vibrant colour and its ability to survive even perched on rocky, precarious cliffs, it has found an important place in New Zealand culture for its strength and beauty, and is regarded as a chiefly tree by Māori. The blossom of the tree is called kahika.

<i>Metrosideros</i> Genus of trees

Metrosideros is a genus of approximately 60 trees, shrubs, and vines mostly found in the Pacific region in the family Myrtaceae. Most of the tree forms are small, but some are exceptionally large, the New Zealand species in particular. The name derives from the Ancient Greek metra or "heartwood" and sideron or "iron". Perhaps the best-known species are the pōhutukawa, northern and southern rātā of New Zealand, and ʻōhiʻa lehua, from the Hawaiian Islands.

<i>Coprosma robusta</i> Species of tree

Coprosma robusta, commonly known as karamu, is a flowering plant in the family Rubiaceae. It can survive in many climates, but is most commonly found in coastal areas, lowland forests, or shrublands. Karamu can grow to be around 6 meters tall, and grow leaves up to 12 centimeters long. Karamu is used for a variety of purposes in human culture. The fruit that karamu produces can be eaten, and the shoots of karamu are sometimes used for medical purposes.

<i>Coprosma</i> Genus of flowering plants

Coprosma is a genus of flowering plants in the family Rubiaceae. It is found in New Zealand, Hawaiian Islands, Borneo, Java, New Guinea, islands of the Pacific Ocean to Australia and the Juan Fernández Islands.

<i>Acaena</i> Genus of flowering plants

Acaena is a genus of about 60 species of mainly evergreen, creeping herbaceous perennial plants and subshrubs in the family Rosaceae, native mainly to the Southern Hemisphere, notably New Zealand, Australia and South America, but with a few species extending into the Northern Hemisphere, north to Hawaii and California.

Invasive species of Australian origin

There are a number of Australian species that have become invasive when introduced into outside Australia or outside Oceania.

<i>Muehlenbeckia</i> Genus of flowering plants

Muehlenbeckia or maidenhair is a genus of flowering plants in the family Polygonaceae. It is native to the borders of the Pacific, including South and North America, Papua New Guinea and Australasia. It has been introduced elsewhere, including Europe. Species vary in their growth habits, many being vines or shrubs. In some environments, rampant species can become weedy and difficult to eradicate.

New Zealand mud snail Species of gastropod

The New Zealand mud snail is a species of very small freshwater snail with a gill and an operculum. This aquatic gastropod mollusk is in the family Tateidae.

<i>Muehlenbeckia complexa</i> Species of flowering plant

Muehlenbeckia complexa, commonly known as pōhuehue, although this name also applies to some other climbers such as Muehlenbeckia australis.

<i>Metrosideros kermadecensis</i> Species of tree

Metrosideros kermadecensis, with common names Kermadec pōhutukawa and New Zealand Christmas bush is an evergreen tree of the myrtle family which is endemic to the volcanic Kermadec Islands about 900 km north-east of New Zealand. The tree produces a brilliant display of red flowers, made up of a mass of stamens and is the dominant forest tree on Raoul Island, growing to 15 m or more. The trunk is up to 1 m or more in diameter. It is very similar to, and often confused with, the pōhutukawa of mainland New Zealand, differing mainly by having smaller, more oval leaves, and by flowering throughout the year. It also resembles the ʻōhiʻa lehua of Hawaiʻi.

<i>Acaena novae-zelandiae</i> Species of plant

Acaena novae-zelandiae, commonly known as red bidibid, bidgee widgee, buzzy and piri-piri bur, is a small herbaceous, prostrate perennial, native to New Zealand, Australia and New Guinea, of the family Rosaceae.

<i>Potamopyrgus</i> Genus of gastropods

Potamopyrgus is a genus of minute freshwater snails with an operculum, aquatic gastropod molluscs or micromolluscs in the family Tateidae.

<i>Phormium tenax</i> Species of flowering plant

Phormium tenax is an evergreen perennial plant native to New Zealand and Norfolk Island that is an important fibre plant and a popular ornamental plant. The plant grows as a clump of long, straplike leaves, up to two metres long, from which arises a much taller flowering shoot, with dramatic yellow or red flowers.

<i>Coprosma repens</i> Species of flowering plant

Coprosma repens is a species of flowering shrub or small tree of the genus Coprosma, in the family Rubiaceae, native to New Zealand. Common names include taupata, tree bedstraw, mirror bush, looking-glass bush, New Zealand laurel and shiny leaf.

<i>Ascarina lucida</i> Species of tree

Ascarina lucida, commonly known as hutu is a species of small tree in the family Chloranthaceae. It is endemic to New Zealand, being common on the West Coast and Nelson regions of the South Island and more rarely found in the North Island. A typical plant association is within the Westland podocarp/broadleaf forests with common understory associates of Blechnum discolor, Pseudowintera colorata, Pseudopanax colensoi and Coprosma lucida. Most genus members are dioecious, producing unisexual male or female flowers on separate plants. Ascarina lucida, the only member of its genus to occur in New Zealand, is monoecious. It will grow to a height of 6m and can have a 30 cm trunk. The leaves which are in opposite pairs are simple, yellowish green in color, have a raised mid rib and are very similar to Laurelia novae-zelandiae. Their margins have prominent teeth which are dark colored at the tips. Ascarina lucida is now nearly extinct in the Taranaki region but was last reported in Oct 1969 at Mt Taranaki, near Pukeiti by Colin Ogle.

Banksia novae-zelandiae is an extinct species of Banksia, known only from fossil leaves found in the South Island of New Zealand.

<i>Flora of Lord Auckland and Campbells Islands</i>

The Flora of Lord Auckland and Campbell's Islands is a description of the plants discovered in those islands during the Ross expedition written by Joseph Dalton Hooker and published by Reeve Brothers in London between 1843 and 1845. Hooker sailed on HMS Erebus as assistant surgeon. It was the first in a series of four Floras in the Flora Antarctica, the others being the Flora of Fuegia, the Falklands, Kerguellen's land, etc (1845–1847), the Flora Novae-Zelandiae (1851–53), and the Flora Tasmaniae (1853–59). They were "splendidly" illustrated by Walter Hood Fitch.

<i>Dictyotus caenosus</i> Species of true bug

Dictyotus caenosus, commonly known as the brown shield bug, is an Australian species of stink bug that has been introduced into New Zealand and New Caledonia.
