Myrtaceae, the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pōhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group. All species are woody, contain essential oils, and have flower parts in multiples of four or five. The leaves are evergreen, alternate to mostly opposite, simple, and usually entire. The flowers have a base number of five petals, though in several genera, the petals are minute or absent. The stamens are usually very conspicuous, brightly coloured, and numerous.
Alyxia is a genus of flowering plants in the family, Apocynaceae. It contains at present 106 species, but Alyxia stellata and A. tisserantii are very variable, might be cryptic species complexes, and are need of further study. It consists of shrubby, climbing or scrambling plants. This genus occurs in China, the Himalayas, Southeast Asia, Australia, New Caledonia and the Pacific Islands. There are 14 species in Australia, 21 in New Caledonia and 7 in the other Pacific Islands, including Hawaiʻi.
Backhousia is a genus of thirteen currently known species of flowering plants in the family Myrtaceae. All the currently known species are endemic to Australia in the rainforests and seasonally dry forests of Queensland, New South Wales and Western Australia.
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.
