Plagianthus is a genus of flowering plants confined to New Zealand and the Chatham Islands. The familial placement of the genus was controversial for many years, but modern genetic studies show it definitely belongs in the Malvaceae subfamily Malvoideae. [3] The name means "slanted flowers". [1]

Description

The type species P. divaricatus is a divaricate shrub which grows at the edges of salt marshes. The other species, P. regius is a tree which in juvenile stage may be divaricate (subsp. regius) or not (subsp. chathamica).

These are the only species recognized currently. In the past, species from related genera such as Hoheria (New Zealand), Asterotrichion , Lawrencia and Gynatrix (Australia) were sometimes assigned to the genus. Instead, all these genera are now grouped in an informal "Plagianthus alliance". [4]

Ericaceae The heather family of flowering plants

The Ericaceae are a family of flowering plants, commonly known as the heath or heather family, found most commonly in acid and infertile growing conditions. The family is large, with c. 4250 known species spread across 124 genera, making it the 14th most species-rich family of flowering plants. The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron, and various common heaths and heathers.

Malvaceae Family of flowering plants

Malvaceae, or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include okra, cotton, cacao and durian. There are also some genera containing familiar ornamentals, such as Alcea (hollyhock), Malva (mallow) and Lavatera, as well as Tilia. The largest genera in terms of number of species include Hibiscus, Sterculia, Dombeya, Pavonia and Sida.

Bombacaceae Family of flowering plants

Bombacaceae were long recognised as a family of flowering plants or Angiospermae. The family name was based on the type genus Bombax. As is true for many botanical names, circumscription and status of the taxon has varied with taxonomic point of view, and currently the preference is to transfer most of the erstwhile family Bombacaceae to the subfamily Bombacoideae within the family Malvaceae in the order Malvales. The rest of the family were transferred to other taxa, notably the new family Durionaceae. Irrespective of current taxonomic status, many of the species originally included in the Bombacaceae are of considerable ecological, historical, horticultural, and economic importance, such as balsa, kapok, baobab and durian.

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

Aleurites is a small genus of arborescent flowering plants in the Euphorbiaceae, first described as a genus in 1776. It is native to China, the Indian Subcontinent, Southeast Asia, Papuasia, and Queensland. It is also reportedly naturalized on various islands as well as scattered locations in Africa, South America, and Florida.

Sterculiaceae was a family of flowering plant based on the genus Sterculia. Genera formerly included in Sterculiaceae are now placed in the family Malvaceae, in the subfamilies: Byttnerioideae, Dombeyoideae, Helicteroideae and Sterculioideae.

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

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.

<i>Craspedia</i> (plant) Genus of Australasian flowering plants of Asteraceae (daisy) family

Craspedia is a genus of flowering plants in the daisy family commonly known as billy buttons and woollyheads. They are native to Australia and New Zealand where they grow in a variety of habitats from sea level to the Alps. The genus is found in every state of Australia except the Northern Territory. In New Zealand, Craspedia is found from East Cape on the North Island south to Stewart Island. It also occurs on Campbell Island and the Chatham Islands.

Malvoideae Subfamily of flowering plants

Malvoideae is a botanical name at the rank of subfamily, which includes in the minimum the genus Malva. It was first used by Burnett in 1835, but was not much used until recently, where, within the framework of the APG System, which unites the families Malvaceae, Bombacaceae, Sterculiaceae and Tiliaceae of the Cronquist system, the aggregate family Malvaceae is divided into 9 subfamilies, including Malvoideae. The Malvoideae of Kubitzki and Bayer includes 4 tribes:-

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

Ripogonum is a genus of flowering plants confined to eastern Australia, New Zealand, and New Guinea. Until recently this genus was included in the family Smilacaceae, and earlier in the family Liliaceae, but it has now been separated as its own family Ripogonaceae.

Taxonomy of <i>Banksia</i>

As with other flowering plants, the taxonomy of Banksia has traditionally been based on anatomical and morphological properties of the Banksia flower, fruiting structure and seed, along with secondary characteristics such as leaf structure and growth habit. Increasingly, molecular evidence from DNA is providing important new insights into relationships within the genus and between this and other genera in the Proteaceae.

Haloragaceae Family of flowering plants in the Eudicot order Saxifragales

Haloragaceae is a eudicot flowering plant family in the order Saxifragales, based on the phylogenetic APG system. In the Cronquist system, it was included in the order Haloragales.

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

Lagunaria is a genus in the family Malvaceae. It is an Australian plant which is native to Lord Howe Island, Norfolk Island and parts of coastal Queensland. It has been introduced to many parts of the world. The genus was named for its resemblance to the earlier genus Laguna Cav., which was named in honour of Andrés Laguna, a Spanish botanist and a physician to Pope Julius III.

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

Brachyglottis is a genus of flowering plants in the aster family, Asteraceae. The genus was erected on November 29, 1775, by Johann Reinhold Forster and Georg Forster. The name was derived from the Greek brachus ("short") and glottis a reference to the size of the ray florets.

Gossypieae Tribe of flowering plants

Gossypieae is a tribe of the flowering plant subfamily Malvoideae. It includes the cotton (Gossypium) and related plants. It is distinguished from the Hibisceae on the basis of embryo structure and its apparently unique possession of glands able to synthesize the pigment gossypol.

<i>Leptecophylla juniperina</i> Species of fruit and plant

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.

Malveae Tribe of flowering plants

Malveae is a tribe of flowering plants in the mallow family Malvaceae, subfamily Malvoideae. The tribe circumscribes approximately 70 genera and 1040 species and has the greatest species diversity out the three tribes that make up Malvoideae. The flowers of Malveae are five-merous with a characteristic staminal column, a trait found throughout Malvoideae. Although there are not many economically important species within Malveae, the tribe includes Althaea officinalis, otherwise known as the Marsh Mallow.

<i>Plagianthus regius</i> Species of tree

Plagianthus regius or lowland ribbonwood is a tree that is endemic to New Zealand. The common name is simply ribbonwood. The Māori name is manatu but is also known as houi, manaui manatu, puruhi and whauwhi.

<i>Balanophora fungosa</i> Species of plant in the family Balanophoraceae

Balanophora fungosa, sometimes known as fungus root is a flowering plant in the family Balanophoraceae and occurs in South Asia, Southeast Asia, Australia and some Pacific Islands. It is an obligate parasite growing on the roots of rainforest trees. The flowering structure is shaped like a puffball but in fact consists of a globe covered with thousands of tiny female flowers. The globe is surrounded at its base by a much smaller number of male flowers. In flower, the plant emits an odour resembling that of mice.

Durioneae is a tribe within the subfamily Helicteroideae of the plant family Malvaceae s.l. The tribe contains at least five genera, including Durio, the genus of tree species that produce Durian fruits.
