Myrtaceae genera

Psidium is a genus of trees and shrubs in the family Myrtaceae. It is native to warmer parts of the Western Hemisphere (Mexico, Central and South America, the West Indies, and the Galápagos Islands). Many of the species bear edible fruits, and for this reason several are cultivated commercially. The most popularly cultivated species is the common guava, Psidium guajava.

Eugenia is a genus of flowering plants in the myrtle family Myrtaceae. It has a worldwide, although highly uneven, distribution in tropical and subtropical regions. The bulk of the approximately 1,100 species occur in the New World tropics, especially in the eastern Brazil's northern Andes, the Caribbean, and the Atlantic Forest (coastal forests). Other centers of diversity include New Caledonia and Madagascar. Many species in the Old World have received a new classification into the genus Syzygium.

Melaleuca () is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles, bottlebrushes or tea-trees (although the last name is also applied to species of Leptospermum). They range in size from small shrubs that rarely grow to more than high, to trees up to . Their flowers generally occur in groups, forming a "head" or "spike" resembling a brush used for cleaning bottles, containing up to 80 individual flowers.

Callistemon is a genus of shrubs in the family Myrtaceae, first described as a genus in 1814. The entire genus is endemic to Australia but widely cultivated in many other regions and naturalised in scattered locations. Their status as a separate taxon is in doubt, some authorities accepting that the difference between callistemons and melaleucas is not sufficient for them to be grouped in a separate genus.

Metrosideros (; ) is a genus of approximately 60 trees, shrubs, and vines in the family Myrtaceae, mostly found in the Pacific region. Most of the tree forms are small, but some are exceptionally large, the New Zealand species in particular. The name derives from the Ancient Greek metra or "heartwood" and sideron or "iron". Perhaps the best-known species are the pōhutukawa (M. excelsa), northern rātā (M. robusta) and southern rātā (M. umbellata) of New Zealand, and ōhia lehua (M. polymorpha) from the Hawaiian Islands.

Leptospermum is a genus of shrubs and small trees in the myrtle family Myrtaceae commonly known as tea trees, although this name is sometimes also used for some species of Melaleuca. Most species are endemic to Australia, with the greatest diversity in the south of the continent, but some are native to other parts of the world, including New Zealand and Southeast Asia. Leptospermums all have five conspicuous petals and five groups of stamens which alternate with the petals. There is a single style in the centre of the flower and the fruit is a woody capsule.

Baeckea is a genus of flowering plants in the myrtle family, Myrtaceae, all but one endemic to Australia. Plants in the genus Baeckea are shrubs or small trees with leaves arranged in opposite pairs, white to deep pink flowers with five sepals and five petals, and five to fifteen stamens that are shorter than the petals.

Ugni is a genus of plants in the myrtle family Myrtaceae, described as a genus in 1848. It is native to western Latin America from the Valdivian temperate rain forests of southern Chile (including the Juan Fernández Islands) and adjacent regions of southern Argentina, north to southern Mexico.

Kunzea is a genus of plants in the family Myrtaceae and is endemic to Australasia. They are shrubs, sometimes small trees and usually have small, crowded, rather aromatic leaves. The flowers are similar to those of plants in the genus Leptospermum but differ in having stamens that are longer than the petals. Most kunzeas are endemic to Western Australia but a few occur in eastern Australia and a few are found in New Zealand. The taxonomy of the genus is not settled and is complicated by the existence of a number of hybrids.

Angophora is a genus of nine species of trees and shrubs in the myrtle family, Myrtaceae. Endemic to eastern Australia, they differ from other eucalypts in having juvenile and adult leaves arranged in opposite pairs, sepals reduced to projections on the edge of the floral cup, four or five overlapping, more or less round petals, and a papery or thin, woody, often strongly ribbed capsule. Species are found between the Atherton Tableland in Queensland and south through New South Wales to eastern Victoria, Australia.
