Lomatia is a genus of 12 species of evergreen flowering plants in the protea family Proteaceae. Within the family, they have been placed, alone, in their own subtribe, Lomatiinae according to Johnson & Briggs 1975 classification of the family and subsequently in Flora of Australia (1995).

The genus has a Pacific Rim distribution, with members native to eastern Australia and southern South America, forming a part of the Antarctic flora. The species range from prostrate shrubs less than 0.5 m (1 ft 8 in) tall to small trees up to 12 m (39 ft) tall.

Genetic analysis using microsatellite markers showed that species found close together geographically are most closely related to each other. Lomatia dentata, then L. hirsuta and L. ferruginea all diverged successively from the lineage that gave rise to Australian species. The three Tasmanian species (with L. tasmanica sister to the other two species) are sister to the mainland Australian group. L. tasmanica is one of the most endangered species, due to its inability to reproduce sexually. On mainland Australia, the far northern L. fraxinifolia is sister to the other five species, all of which are found in southeastern Australia. L. fraseri and L. myricoides are sister taxa, with L. ilicifolia sister to them, while L. arborescens and L. silaifolia are each other's closest relatives. [1] Strong genomic filters may facilitate continued gene flow between species without the danger of assimilation.

<i>Lomatia tasmanica</i> Tasmanian shrub from the family Proteaceae

Lomatia tasmanica, commonly known as King's lomatia, is a shrub of the family Proteaceae native to Tasmania. Growing up to 8 metres (26 ft) tall, the plant has shiny green pinnate (lobed) leaves and bears red flowers in the summer, but yields neither fruit nor seeds. King's lomatia is unusual because all of the remaining plants are genetically identical clones. Because it has three sets of chromosomes and is therefore sterile, reproduction occurs only vegetatively: when a branch falls, that branch grows new roots, establishing a new plant that is genetically identical to its parent.

<i>Embothrium</i> Genus of trees

Embothrium is a genus of two to eight species in the plant family Proteaceae, native to southern South America, in Chile and adjacent western Argentina; the genus occurs as far south as Tierra del Fuego. Common names include Chilean firebush in English, notro in Argentina, ciruelillo, fosforito or notro chileno in Chilean Spanish.

<i>Banksia integrifolia</i> Tree in the family Proteaceae, from Australias east coast

Banksia integrifolia, commonly known as the coast banksia, is a species of tree that grows along the east coast of Australia. One of the most widely distributed Banksia species, it occurs between Victoria and Central Queensland in a broad range of habitats, from coastal dunes to mountains. It is highly variable in form, but is most often encountered as a tree up to 25 metres (82 ft) in height. Its leaves have dark green upper surfaces and white undersides, a contrast that can be striking on windy days.

<span class="mw-page-title-main">Proteaceae</span> Family of ducks plants

The Proteaceae form a family of flowering plants predominantly distributed in the Southern Hemisphere. The family comprises 83 genera with about 1,660 known species. Australia and South Africa have the greatest concentrations of diversity. Together with the Platanaceae, Nelumbonaceae and in the recent APG IV system the Sabiaceae, they make up the order Proteales. Well-known Proteaceae genera include Protea, Banksia, Embothrium, Grevillea, Hakea, and Macadamia. Species such as the New South Wales waratah, king protea, and various species of Banksia, Grevillea, and Leucadendron are popular cut flowers. The nuts of Macadamia integrifolia are widely grown commercially and consumed, as are those of Gevuina avellana on a smaller scale.

<span class="mw-page-title-main">Grevilleoideae</span> Subfamily of plants in the family Proteaceae, mainly from the Southern Hemisphere

The Grevilleoideae are a subfamily of the plant family Proteaceae. Mainly restricted to the Southern Hemisphere, it contains around 46 genera and about 950 species. Genera include Banksia, Grevillea, and Macadamia.

Banksieaephyllum is a plant genus that encompasses organically preserved fossil leaves that can be attributed to the Proteaceae tribe Banksieae, but cannot be attributed to a genus.

<span class="mw-page-title-main">Bentham's taxonomic arrangement of Banksia</span> 1870 arrangement of the Australian endemic plant genus Banksia

George Bentham's taxonomic arrangement of Banksia was published in 1870, in Volume 5 of Bentham's Flora Australiensis. A substantial improvement on the previous arrangement, it would stand for over a century. It was eventually replaced by Alex George's 1981 arrangement, published in his classic monograph The genus Banksia L.f. (Proteaceae).

<span class="mw-page-title-main">George's taxonomic arrangement of Dryandra</span> 1996 arrangement of the Australian endemic plant series Dryandra in the genus Banksia

Alex George's taxonomic arrangement of Dryandra was the first modern-day arrangement of that taxon. First published in Nuytsia in 1996, it superseded the arrangement of George Bentham, which had stood for over a hundred years; it would later form the basis for George's 1999 treatment of Dryandra for the Flora of Australia. In accordance with contemporary thinking, George treated Dryandra as a genus, dividing it into three subgenera, the largest of which was divided into 24 series. The arrangement stood until 2007, when Dryandra was transferred into Banksia as B. ser. Dryandra. No alternative has yet been proposed.

<i>Dryandra</i> subg. <i>Dryandra</i> Obsolete subgenus within the former genus Dryandra

Dryandra subg. Dryandra is an obsolete clade of plant. It was a series within the former genus Dryandra. The name was first published at sectional rank as Dryandra verae in 1830, before being renamed Eudryandra in 1847, the replaced by the autonym at subgenus rank in 1996. It was ultimately discarded in 2007 when Austin Mast and Kevin Thiele sunk Dryandra into Banksia.

<i>Lomatia fraseri</i> Plant of the family Proteaceae native to eastern Australia

Lomatia fraseri, commonly known as tree lomatia, forest lomatia or silky lomatia is a plant of the family Proteaceae native to eastern Australia. It grows as a shrub or small tree, reaching 8–11 metres (26–36 ft) high, with highly variable leaves. The cream to white inflorescences appear over summer. It is found in rainforest margins, gullies and heathland in mountainous regions of Victoria and New South Wales. It regenerates from fire by regrowing from a lignotuber.
