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.
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.
Flindersia is a genus of 17 species of small to large trees in the family Rutaceae. They have simple or pinnate leaves, flowers arranged in panicles at or near the ends of branchlets and fruit that is a woody capsule containing winged seeds. They grow naturally in Australia, the Moluccas, New Guinea and New Caledonia.
Leucopogon is a genus of about 150-160 species of shrubs or small trees in the family Ericaceae, in the section of that family formerly treated as the separate family Epacridaceae. They are native to Australia, New Zealand, New Caledonia, the western Pacific Islands and Malaysia, with the greatest species diversity in the south-west of Western Australia. Plants in this genus have leaves with a few more or less parallel veins, and tube-shaped flowers usually with a white beard inside.
Prostanthera, commonly known as mintbush or mint bush, is a genus of about 100 species of flowering plants in the mint family Lamiaceae, and all are endemic to Australia. Plants are usually shrubs, rarely trees with leaves in opposite pairs. The flowers are arranged in panicles in the leaf axils or on the ends of branchlets. The sepals are joined at the base with two lobes. The petals are usually blue to purple or white, joined in a tube with two "lips", the lower lip with three lobes and the upper lip with two lobes or notched.
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.
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.
Homoranthus is a genus of about thirty species of plants in the myrtle family Myrtaceae and all are endemic to Australia. Plants in this genus share similarities with those in both Darwinia and Verticordia. They are shrubs with their leaves arranged in opposite pairs and with flowers appearing either singly or in small groups, usually in upper leaf axils. They are found in Queensland, New South Wales and South Australia. The genus was first described in 1836. None of the species is common nor are they well-known in horticulture.
Cryptandra is a genus of flowering plants in the family Rhamnaceae and is endemic to Australia. Most plants in the genus Cryptandra are spiny, heath-like shrubs with small, clustered leaves and flowers crowded at the ends of branches, the flowers are usually small, surrounded by brown bracts, and with tube-shaped hypanthium, the petals hooded over the anthers.
Micromyrtus is a genus of flowering plants in the family Myrtaceae and is endemic to Australia. Plants in the genus Micromyrtus are shrubs with simple leaves arranged in opposite pairs, and white, pink or yellow flowers arranged in upper leaf axils, the flowers with five sepals five petals and five or ten stamens.
Xanthostemon is a genus of plants in the myrtle family Myrtaceae, first described in 1857 by the German–born Australian botanist Ferdinand von Mueller. The genus is distributed across Malesia, Papuasia and northern Australia. The genera Pleurocalyptus and Purpureostemon from New Caledonia are morphologically close to Xanthostemon.
Chamelaucieae is a tribe of flowering plants within the family Myrtaceae, mostly from Australia, with a few species in New Caledonia and south-east Asia.
Kardomia is a genus of flowering plants in the family Myrtaceae and is endemic to eastern Australia. Plants in the genus Kardomia are shrubs with leaves arranged in opposite pairs and with flowers with a ridged or rough floral cup, five petals and four to thirteen stamens.
Cyanothamnus is a genus of flowering plant in the family Rutaceae, native to Australia. Plants in the genus Cyanothamnus are erect or spreading shrubs usually with pinnate leaves arranged in opposite pairs, the leaves or leaflets flat. The flowers are arranged singly or in cymes with minute bracts. The petals are usually pink or white, sometimes blue or yellowish-green.
Aggreflorum longifolium is a species of shrub or small tree that is endemic to north-western Australia. It has weeping branches, smooth bark, pale green linear leaves, small white flowers and thin-walled fruit.
Aggreflorum anfractum is a species of spreading shrub that is endemic to Queensland. It has a smooth, twisted trunk, linear leaves, white flowers borne in leaf axils and bell-shaped to hemispherical fruit. It grows on rocky ridges and cliff edges.
Aggreflorum benwellii is a species of shrub that is endemic to the Nymboida National Park in New South Wales. It has smooth bark, young branches with conspicuous flanges, narrow elliptical leaves, white flowers and thin-walled, bell-shaped to hemispherical fruit.
Aggreflorum luehmannii is a species of shrub or small tree that is endemic to Queensland. It has glossy green elliptic leaves, white flowers, and fruit that falls from the plant shortly after the seeds are released.
Aggreflorum pallidum is a species of spreading shrub that is endemic to Queensland. It has thin, firm, rough bark, narrow lance-shaped leaves, white flowers arranged in groups of two or three on side shoots and fruit that remains on the plant until it dies.
Aggreflorum purpurascens, commonly known as the purple-stemmed turkey bush, is a shrub or small tree that is endemic to far north Queensland. It has bark that is purple when new, elliptical to broadly lance-shaped leaves, relatively small white flowers arranged in pairs, and small fruit that falls from the plants when the seeds are released.
