The Myrtaceae or Myrtle family are a family of dicotyledon plants, placed within the order Myrtales. Plants are living Organisms belonging to the kingdom Plantae. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group Magnoliopsida is the Botanical name for a class of Flowering plants By definition the class will include the family Magnoliaceae, but its The Myrtales are an order of Flowering plants placed as a basal group within the rosid group of Dicotyledons (not a member of eurosids I or eurosids II Antoine Laurent de Jussieu ( April 12, 1748 - September 17, 1836) was a French Botanist, notable as the first to propose Dicotyledons, or "dicots", is a name for a group of Flowering plants whose Seed typically has two embryonic leaves or Cotyledons There Plants are living Organisms belonging to the kingdom Plantae. The Myrtales are an order of Flowering plants placed as a basal group within the rosid group of Dicotyledons (not a member of eurosids I or eurosids II Myrtle, clove, guava, feijoa, allspice, and eucalyptus belong here. The Myrtle ( Myrtus) is a genus of one or two species of Flowering plants in the family Myrtaceae, native to southern Europe and north This article is about the Spice; for other meanings see Clove (disambiguation. Guava is a Genus of about 100 Species of Tropical Shrubs and small Trees in the myrtle family Myrtaceae. The Feijoa ( Feijoa sellowiana, synonym Acca sellowiana) also known as Pineapple Guava or Guavasteen, is an Evergreen Allspice, also called Jamaica pepper,"Kurundu" Myrtle pepper, pimento, or newspice, is a Spice which is the dried unripe Eucalyptus (From Greek ευκάλυπτος meaning "well covered" is a diverse Genus of Trees (and a few shrubs the members of which All species are woody, with essential oils, and flower parts in multiples of four or five. An essential oil is a concentrated Hydrophobic Liquid containing volatile Aroma compounds from Plants They are also known as volatile One notable character of the family is that the phloem is located on both sides of the xylem, not just outside as in most other plants. In Vascular plants phloem is the living tissue that carries organic Nutrients (known as photosynthate particularly Sucrose, a sugar to In Vascular plants xylem is one of the two types of transport tissue Phloem being the other The leaves are evergreen, alternate to mostly opposite, simple, and usually with an entire (not toothed) margin. In Botany, a leaf is an above-ground Plant organ specialized for Photosynthesis. In Botany, an Evergreen plant is a plant having leaves all year round The flowers have a base number of five petals, though in several genera the petals are minute or absent. A flower, also known as a bloom or Blossom, is the reproductive structure found in Flowering plants (plants of the division Magnoliophyta, also The stamens are usually very conspicuous, brightly coloured and numerous. The stamen ( Plural stamina or stamens, from Latin stamen meaning "thread of the warp " is the male
The family Myrtaceae has at least 3000 species distributed in 130-150 genera. They have a wide distribution in tropical and warm-temperate regions of the world, and are typically common in many of the world's biodiversity hotspots. A biodiversity hotspot is a Biogeographic region with a significant reservoir of biodiversity that is threatened with destruction Genera with capsular fruits such as Eucalyptus, Corymbia, Angophora, Leptospermum, Melaleuca, Metrosideros are absent from the Americas, apart from the monotypic genus Tepualia in Chile. Eucalyptus (From Greek ευκάλυπτος meaning "well covered" is a diverse Genus of Trees (and a few shrubs the members of which Corymbia is a genus of about 113 species of tree that were classified as Eucalyptus species until the mid-1990s Angophora is a genus of ten species of Trees or large Shrubs in the myrtle family ( Myrtaceae) native to eastern Australia. Leptospermum is a genus of about 80-86 species of plants in the myrtle family Myrtaceae. Melaleuca is a Genus of Plants in the myrtle family Myrtaceae. Metrosideros is a genus of approximately 50 Trees Shrubs and Vines native to the islands of the Pacific Ocean, from the Philippines Chile, officially the Republic of Chile ( Spanish:) is a country in South America occupying a long and narrow Coastal strip wedged between the Genera with fleshy fruits have their greatest concentrations in eastern Australia and Malesia (the Australasia ecozone) and the Neotropics. For a topic outline on this subject see List of basic Australia topics. Malesia is a biogeographical region straddling the boundary of the Indomalaya and Australasia ecozones Malesia was first identified as a Floristic The Australasian zone is an ecological region that is coincident but not synonymous (by some definitions with the geographic Region of Australasia In Biogeography, Neotropic or Neotropical refers to one of the world's eight terrestrial Ecozones This ecozone includes South and Central America the Eucalyptus is a dominant, nearly ubiquitous genus in the more mesic parts of Australia and extends north sporadically to the Philippines. The Philippines ( Filipino: Pilipinas, officially known as the Republic of the Philippines (fil ''Republika ng Pilipinas'' RP Eucalyptus regnans is the tallest flowering plant in the world. Eucalyptus regnans, known variously by the common names Mountain Ash, Victorian Ash, Swamp Gum, Tasmanian Oak or Stringy Other important Australian genera are Callistemon (bottlebrushes), Syzygium, and Melaleuca (paperbarks). Syzygium is a Genus of Flowering plants belonging to the myrtle family Myrtaceae. Melaleuca is a Genus of Plants in the myrtle family Myrtaceae. The genus Osbornia, native to Australasia, are mangroves. Mangroves (generally are Trees and Shrubs that grow in saline coastal habitats in the Tropics and Subtropics. Eugenia, Myrcia, and Calyptranthes are among the larger genera in the neotropics. Eugenia is a Genus of Flowering plants in the myrtle family Myrtaceae. Myrcia is a genus of the Flowering plant family Myrtaceae.;Selected species Myrcia albobrunnea
Historically, the Myrtaceae were divided into two subfamilies.
- Subfamily Myrtoideae have fleshy fruits and opposite, entire leaves. Most genera in this subfamily have one of three easily recognized types of embryos. The genera of Myrtoideae can be very difficult to distinguish in the absence of mature fruits. The Myrtoideae are found worldwide in subtropical and tropical regions, with centres of diversity in the Neotropics, northeastern Australia, and Malesia.
- Subfamily Leptospermoideae has dry, indehiscent fruits (capsules) and leaves arranged spirally or alternate. The Leptospermoideae are found mostly in Australasia, with a centre of diversity in Australia. Many genera in Western Australia have greatly reduced leaves and flowers typical of more xeric habitats.
The division of the Myrtaceae into the Leptospermoideae and Myrtoideae was challenged by a number of authors, including Johnson and Briggs (1984), who identified 14 tribes or clades within the Myrtaceae, and found the Myrtoideae to be polyphyletic. A molecular analysis by Wilson, O'Brien et al. (2001) found eleven strong groupings within the family, including many of the groupings identified by Johnson and Briggs. Further molecular analysis by Sytsma and Litt (2002) found that the Neotropic Myrtoideae grouping fit within the paraphyletic Leptopermoideae.
The genera Heteropyxis and Psiloxylon, which some authorities include in Myrtaceae, are here placed as separate families by most authors, based on evidence of their divergence before the origin of the common ancestor of the Myrtaceae. Heteropyxis is a genus which includes three species of small evergreen Trees It was previously placed along in family Heteropyxidaceae, but is now Psiloxylon mauritianum is species of Flowering plant, the sole species of family Psiloxylaceae.
