Gahnia (sawsedge, saw-sedge) is a genus of sedges native to China, Southeast Asia, New Guinea, Australia, New Zealand and a number of Pacific Islands. [1] [2] [3] [4] The common name is due to the toothed margins. [4] It often forms tussocks.
Accepted species: [1]
The species Gahnia lanaiensis has been known as a rare endemic plant from the Hawaiian island of Lanai and it was federally listed as an endangered species of the United States. In 2010, however, research suggested that the Lanai plants are actually Gahnia lacera introduced from New Zealand in the early 20th century. [7]
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.
Myoporum is a genus of flowering plants in the figwort family, Scrophulariaceae. There are 30 species in the genus, eighteen of which are endemic to Australia although others are endemic to Pacific Islands, including New Zealand, and one is endemic to two Indian Ocean islands. They are shrubs or small trees with leaves that are arranged alternately and have white, occasionally pink flowers and a fruit that is a drupe.
Cordyline is a genus of about 15 species of woody monocotyledonous flowering plants in family Asparagaceae, subfamily Lomandroideae. The subfamily has previously been treated as a separate family Laxmanniaceae, or Lomandraceae. Other authors have placed the genus in the Agavaceae. Cordyline is native to the western Pacific Ocean region, from New Zealand, eastern Australia, southeastern Asia and Polynesia, with one species found in southeastern South America.
Arthropodium is a genus of herbaceous perennial plants in the subfamily Lomandroideae of the family Asparagaceae. It is native to Australia, New Zealand, New Caledonia and Madagascar.
Patersonia is a genus of flowering plants in the family Iridaceae commonly known as native iris or native flag. It was first described as a genus in 1807 by Robert Brown. It is native to Australia, New Guinea, New Caledonia, and insular Southeast Asia. The genus name is a tribute to the first Lieutenant Governor of New South Wales in Australia, William Paterson.
Centrolepis is a genus of small herbaceous plants in the family Restionaceae known as thorn grass scales, with about 25 species native to Australia, New Zealand, New Guinea, and south-east Asia as far north as Hainan Dao. APG III system classifies this genus in the Centrolepidaceae family.
Dianella is a genus of about forty species of flowering plants in the monocot family Asphodelaceae and are commonly known as flax lilies. Plants in this genus are tufted herbs with more or less linear leaves and bisexual flowers with three sepals more or less similar to three petals and a superior ovary, the fruit a berry. They occur in Africa, South-east Asia, the Pacific Islands, New Zealand and Australia.
Melodinus is a genus of plant in the family Apocynaceae, first described as a genus in 1776. It is native to Indomalaya, Meganesia and various islands in the western Pacific. A type of monoterpenoid indole alkaloids called melodinines can be isolated from Melodinus plants.
Uncinia is a genus of flowering plants in the family Cyperaceae, known as hook-sedges in Australia and as hook grasses or bastard grasses in New Zealand. The genus is characterised by the presence of a long hook formed by an extension of the rachilla, which is used to attach the fruit to passing animals (epizoochory), especially birds, and it is this feature which gives the genus its name, from the Latin uncinus, meaning a hook or barb.
Thysanotus is a genus of perennial herbs in the family Asparagaceae, subfamily Lomandroideae. They are mostly native to Australia with 45 of the 50 known species occurring in Western Australia alone, although a few species range northward into New Guinea and Southeast Asia as far north as southern China.
Lepidosperma is a genus of flowering plant of the family Cyperaceae. Most of the species are endemic to Australia, with others native to southern China, southeast Asia, New Guinea, New Caledonia and New Zealand.
Pratia is a genus of flowering plants in the family Campanulaceae, native to Asia, Australia and New Zealand. One study has said, "It is clear that the segregate genera Hypsela, Isotoma, and Pratia are no longer applicable to the New Zealand species of Lobeliaceae, and these are henceforth treated as Lobelia."
Parsonsia is a genus of woody vines in the family Apocynaceae. Species occur throughout Indomalaya, Australasia and Melanesia.
Leptecophylla juniperina is a species of flowering plant in the family Ericaceae. The species is native to New Zealand and the Australian states of Tasmania and Victoria. The plant's fruit is edible, raw or cooked. Plants grow best in areas with moderate winters and cool moist summers.

Cryptostylis, commonly known as tongue orchids, is a genus of flowering plants from the orchid family. Tongue orchids are terrestrial herbs with one to a few stalked leaves at the base of the flowering stem, or leafless. One to a few dull coloured flowers are borne on an erect flowering stem. The most conspicuous part of the flower is the labellum, compared to the much reduced sepals and petals. At least some species are pollinated by wasps when they attempt to mate with the flower. There are about twenty five species found in South Asia, Southeast Asia and the South Pacific.
Hesperilla chrysotricha, the chrysotricha skipper or goldenhaired sedge-skipper, is a butterfly of the family Hesperiidae. It is found in the Australian states of Victoria, Tasmania, South Australia and Western Australia.

Gahnia aspera known as the rough saw-sedge or round sawsedge is a tussock forming perennial plant, often seen in moist situations. The long strap like leaves grow to 80 cm long.
