Althenia bilocularis is a plant found in both Australia and New Zealand, [3] in fresh to brackish waters. In Australia it is found in all mainland states with the exception of the Northern Territory. [4] In New Zealand it is found on the North, South and Chatham Islands. [5]
It was first described as Lepilaena bilocularis by Thomas Kirk in 1896. [1] [6] It was transferred to the genus, Althenia , in 1927 by Leonard Cockayne. [1] [2] This change by Cockayne is supported by DNA analyses. [7]
Nothofagus, also known as the southern beeches, is a genus of 43 species of trees and shrubs native to the Southern Hemisphere in southern South America and east and southeast Australia, New Zealand, New Guinea, and New Caledonia. The species are ecological dominants in many temperate forests in these regions. Some species are reportedly naturalised in Germany and Great Britain. The genus has a rich fossil record of leaves, cupules, and pollen, with fossils extending into the late Cretaceous period and occurring in Australia, New Zealand, Antarctica, and South America.
The genus Eudyptula contains two species of penguin, found in southern Australia, Tasmania, and New Zealand. They are commonly known as the little penguin, little blue penguin, or, in Australia, fairy penguin. In the language of the Māori people of New Zealand, little penguins are known as kororā.
The Potamogetonaceae, commonly referred to as the pondweed family, is an aquatic family of monocotyledonous flowering plants. The roughly 110 known species are divided over six genera. The largest genus in the family by far is Potamogeton, which contains about 100 species.
Leonard Cockayne is regarded as New Zealand's greatest botanist and a founder of modern science in New Zealand.
Veronica is the largest genus in the flowering plant family Plantaginaceae, with about 500 species. It was formerly classified in the family Scrophulariaceae. Common names include speedwell, bird's eye, and gypsyweed.
Olearia, most commonly known as daisy-bush, is a genus of flowering plants belonging to the family Asteraceae, the largest of the flowering plant families in the world. Olearia are found 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. All bear the familiar daisy-like composite flowerheads in white, pink, mauve or purple.
Carmichaelia is a genus of 24 plant species belonging to Fabaceae, the legume family. All but one species are native to New Zealand; the exception, Carmichaelia exsul, is native to Lord Howe Island and presumably dispersed there from New Zealand.
Dracophyllum is a genus of plants belonging to the family Ericaceae, formerly Epacridaceae. There are 61 species in the genus, mostly shrubs, but also cushion plants and trees, found in New Zealand, Australia, Lord Howe Island and New Caledonia. The name Dracophyllum, meaning dragon-leaf, refers to their strong outward similarity to the unrelated Dracaena, sometimes known as dragon tree. Although dicotyledonous, they resemble primitive monocots with their slender leaves concentrated in clumps at the ends of the branches; they are sometimes called grass-trees.
Celmisia is a genus of perennial herbs or subshrubs, in the family Asteraceae. Most of the species are endemic to New Zealand; several others are endemic to Australia.
Althenia is a genus of aquatic plants of the family Potamogetonaceae. This has long been a group of two species in the Mediterranean Europe and South Africa, but in 2016 was revised to include an Australasian relative, Lepilaena.
Harry Howard Barton Allan was a New Zealand teacher, botanist, scientific administrator, and writer. Despite never receiving a formal education in botany, he became an eminent scientist, publishing over 100 scientific papers, three introductory handbooks on New Zealand plants, and completing the first volume of a flora in his lifetime.
Maytenus bilocularis, commonly known as orangebark, is a tree that is endemic to eastern Australia. It grows to 10 metres high and has leaves with toothed edges that are 3 to 9 cm long and 1.3 to 3 cm wide and elliptic, ovate or obovate in shape.
Althenia australis is a species of aquatic plant in the family Potamogetonaceae. It is found in fresh to brackish waters in Australia. This species has been transferred from Lepilaena.
Althenia preissii is a plant found in fresh to brackish waters in Australia. This species has been transferred from the genus Lepilaena.
Althenia marina is a plant found in brackish to marine waters in Australia. The species has been transferred from the genus Lepilaena.
Althenia cylindrocarpa is a species of aquatic plant in the family Potamogetonaceae. It is found in fresh to brackish waters in Australia. This species has been transferred from Lepilaena.
Leptinella filiformis, or slender button daisy, is a species of flowering plant in the daisy family, found only in the north-eastern part of the South Island of New Zealand. Thought to be extinct by the 1980s, it was rediscovered growing on a Hanmer Springs hotel lawn in 1998, and in the wild in 2015.
Carmichaelia astonii is a species of pea in the family Fabaceae. It is found only in South Island of New Zealand. Its conservation status (2018) is "Nationally vulnerable" under the New Zealand Threat Classification System.
Carmichaelia appressa is a species of pea in the family Fabaceae. It is found only in the South Island of New Zealand. Its conservation status (2018) is "At Risk - Naturally Uncommon" under the New Zealand Threat Classification System.
Myosotis colensoi is a species of flowering plant in the family Boraginaceae, endemic to the South Island of New Zealand. Thomas Kirk described the species in 1896. Plants of this species of forget-me-not are perennial rosettes with bracteate inflorescences and white corollas.
