Melaleuca is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles or tea-trees. They range in size from small shrubs that rarely grow to more than 16 m (52 ft) high, to trees up to 35 m (115 ft). Their flowers generally occur in groups, forming a "head" or "spike" resembling a brush used for cleaning bottles, containing up to 80 individual flowers.
Myrtaceae or the myrtle family is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pohutukawa, 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.
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.
Calothamnus quadrifidus, commonly known as one-sided bottlebrush, is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. The common name alludes to the arrangement of the flowers in the inflorescence which line up on one side of the stem. It is a shrub with grey-green, pine-like foliage covered with soft hairs and red, four-part flowers in spring. Widely cultivated because of its attractive foliage, colourful, unusual and prolific flowers, it grows in a variety of habitats and soils. In 2010, Alex George published a review of the species based on recent research and described a number of new subspecies.
Eremaea is a genus of woody shrubs and small trees in the family Myrtaceae and is endemic to the south-west of Western Australia. Little study of the genus as a whole had been undertaken until Roger Hnatiuk researched Eremaea and published a paper in 1993, A revision of the genus Eremaea (Myrtaceae) in Nuytsia. The first species to be described was Eremaea pauciflora in 1837 and by 1964, the number of species known had increased to 12. Hnatiuk recognised 16 species, 5 subspecies and a number of varieties.
Verticordia aereiflora is a flowering plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a thin but bushy shrub with small leaves and greenish-yellow flowers with red spots and red fringes on the sepals.
Verticordia attenuata is a flowering plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a shrub with a single main stem, small leaves and pink to purple flowers which fade to white as they age. It usually grows in sand in areas that are wet in winter, often amongst grasses and is found in coastal areas near Bunbury.
Verticordia is a genus of more than 100 species of plants commonly known as featherflowers, in the myrtle family, Myrtaceae. They range in form from very small shrubs such as V. verticordina to trees like V. cunninghamii, some spindly, others dense and bushy, but the majority are woody shrubs up to 2.0 m (7 ft) tall. The flowers are variously described as "feathery", "woolly" or "hairy" and are found in most colours except blue. They often appear to be in rounded groups or spikes but in fact are always single, each flower borne on a separate stalk in a leaf axil. Each flower has five sepals and five petals all of a similar size with the sepals often having feathery or hairy lobes. There are usually ten stamens alternating with variously shaped staminodes. The style is simple, usually not extending beyond the petals and often has hairs near the tip. All but two species are found in Southwest Australia, the other two occurring in the Northern Territory.
Lamarchea is a genus of shrub in the myrtle family Myrtaceae described as a genus in 1830. The entire genus is endemic to Australia.
- Lamarchea hakeifoliaGaudich. - Shire of Irwin in Western Australia
- Lamarchea sulcataA.S.George - Western Australia, Northern Territory
Melaleuca bisulcata is a plant in the myrtle family, Myrtaceae and is endemic to the a relatively small area on the west coast of Western Australia. It is difficult to distinguish this species from Melaleuca psammophila except on differences in the shape of the calyx lobes.
Persoonia sulcata is a plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is a small, erect or low spreading shrub with narrow, linear leaves and cylindrical yellow flowers arranged singly or in groups of up to three in leaf axils. It grows in woodland or on rocky slopes and is found in several disjunct populations.
Acacia sulcata is a shrub of the genus Acacia and the subgenus Plurinerves that is endemic to an area of south western Australia.
Hakea sulcata, commonly known as furrowed hakea, is a plant in the family Proteaceae that is endemic to Western Australia. It is a prickly shrub with grooved, cylindrical leaves, sweetly-scented flowers and relatively small fruit.
Verticordia tumida, commonly known as summer featherflower, is a flowering plant in the myrtle family, Myrtaceae and is endemic to the north-west of Western Australia. It is an open shrub with very small leaves and clusters of deep pink flowers from late spring to early winter.
Verticordia wonganensis is a flowering plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a shrub which grows near Wongan Hills and has a single main stem, small leaves and spike-like groups of large, pink, feathery flowers.
Verticordia × eurardyensis, commonly known as Eurardy magenta, is a flowering plant in the myrtle family, Myrtaceae and is endemic to a small area in the south-west of Western Australia. It is a shrub similar to both Verticordia dichroma and Verticordia spicata which grow in the same area and is thought to be a stable hybrid between those two species. It has mostly egg-shaped leaves and spike-like groups of dark magenta-coloured flowers which fade to straw-coloured, in late spring and early summer.
Grevillea sulcata is a shrub of the genus Grevillea native to an area in the Great Southern region of Western Australia.
Calytrix asperula, commonly known as brush starflower, is a species of plant in the myrtle family Myrtaceae that is endemic to Western Australia.
Lamarchea hakeifolia is a member of the family Myrtaceae endemic to Western Australia.
Melaleuceae is a tribe in the plant family Myrtaceae from south-east Asia and Oceania, with a main center of diversity in Australia.
