Myrtaceae
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 (i.e., without a toothed margin). 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. Evolutionary history Scientists hypothesize that the family Myrtaceae arose between 60 and 56 million years ago (Mya) during the Paleocene era. Pollen fossils have been sourced to the ancient supercontinent Gondwana. The breakup of Gondwana during the Cretaceous period (145 to 66 Mya) geographically isolated disjunct taxa and allowed for rapid speciation; i ...

Beaufortia (plant)
''Beaufortia '' is a genus of woody shrubs and small trees in the family Myrtaceae and is endemic to Southwest Australia. The genus ''Beaufortia'' is closely related to ''Melaleuca'', ''Calothamnus'', ''Regelia'' and several others, differing mainly in the way the anthers are attached to the stalks of the stamens, and in the way they open to release their pollen. ''Beaufortia'' anthers are attached at one end and open by splitting at the other. Description Plants in the genus ''Beaufortia'', sometimes commonly known as bottlebrush are evergreen shrubs with very small, glandular, aromatic leaves usually oppositely arranged. The tallest are up to in height. Most are andromonoecious, meaning they have both male and bisexual flowers on one plant. The flowers are in spikelike or headlike inflorescences. The flower has five triangular sepals and five white, yellow, red, pink, or purple petals, which are sometimes hairy. The petals usually fall off as the flower opens, or shortly after ...

Melaleuca
''Melaleuca'' () is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles 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. Melaleucas are an important food source for nectarivorous insects, birds, and mammals. Many are popular garden plants, either for their attractive flowers or as dense screens and a few have economic value for producing fencing and oils such as "tea tree" oil. Most melaleucas are endemic to Australia, with a few also occurring in Malesia. Seven are endemic to New Caledonia, and one is found only on (Australia's) Lord Howe Island. Melaleucas are found in a wide variety of habitats. Many are adapted for life in swamp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callistemon
''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. Description ''Callistemon'' species have commonly been referred to as bottlebrushes because of their cylindrical, brush like flowers resembling a traditional bottle brush. They are mostly found in the more temperate regions of Australia, especially along the east coast and typically favour moist conditions so when planted in gardens thrive on regular watering. However, two species are found in Tasmania and several others in the south-west of Western Australia. At least some species are drought-resistant and some are used in ornamental landscaping elsewhere in the world. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calothamnus
''Calothamnus'' is a genus of shrubs in the family Myrtaceae and is endemic to the south-west of Western Australia. The common names one-sided bottlebrush or claw flower are given to some species due to their having the flowers clustered on one side of the stem or because of the claw-like appearance of their flowers. ''Calothamnus'' species are generally medium to tall woody shrubs with crowded leaves. In most species the leaves are crowded and linear in shape, and the flowers are usually arranged in dense clusters. The petals are small and fall off the flower soon after it opens but the stamens are long, numerous and usually bright red. Description Plants in the genus ''Calothamnus'' are medium to tall shrubs, sometimes low-growing ground covers. The leaves are linear or narrow lance-shaped with the narrower end towards the base, usually glabrous and have distinct oil glands. The flowers are in small groups or dense spikes on leafless, older stems or between the leaves on y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conothamnus
''Conothamnus'' is a genus of flowering plants in the family Myrtaceae and is endemic to the south-west of Western Australia. They are woody shrubs similar to melaleucas but differ in that their leaves are usually arranged in opposite pairs and the maximum number of seeds per fruit is three. (Melaleucas usually have alternately arranged leaves and there may be hundreds of very fine seeds in each woody capsule.) Description Plants in the genus ''Conothamnus'' are shrubs with their thinner branches covered with silky hairs. Their leaves are small, arranged in pairs and dotted with oil glands. The flowers have both male and female parts or sometimes have only fertile male parts. The flowers are arranged in small heads or spikes in the angles of leaves near the ends of the branches and are a shade of white to yellow. They have 5 sepals and 5 petals, except in '' Conothamnus aureus'' which appears to lack petals. There are many stamens, arranged in 5 bundles around the edge of th ...

Regelia
''Regelia'' is a genus of flowering plants in the family Myrtaceae and is endemic (ecology), endemic to the Southwest_Australia, south-west of Western Australia. The genus is composed of five species of small leaved, evergreen shrubs which have heads of flowers on the ends of branches which continue to grow after flowering. Another species, previously known as ''Regelia punicea'' and which is endemic to Kakadu National Park in the Northern Territory, has been transferred to ''Melaleuca punicea''. Description Plants in the genus ''Regelia'' are woody, evergreen shrubs ranging in height from . Their leaves are small, arranged in opposite pairs or spirally and are noted for bearing essential oils. Their flowers are pinkish purple, rarely red, and are arranged in heads on the ends of branches which continue to grow after flowering. The flowers have 5 sepals, 5 petals and numerous stamens arranged in 5 bundles around the edge of the flower. In many respects, they are similar to plan ...

Phymatocarpus
''Phymatocarpus'' is a genus of flowering plants in the family Myrtaceae and is endemic to the south-west of Western Australia. All three species are shrubs with pink to purple flowers. Description Plants in the genus ''Phymatocarpus'' are shrubs which grow to a height of . Their leaves are small and are dotted with oil glands. The flowers are arranged in almost spherical heads on the ends of the branches and have 5 oval sepals, 5 petals and up to 75 stamens. The stamens are in a ring around the hypanthium, but above the ring are joined in 5 bundles. The stamens are all longer than the petals and give the flowers their pink to purple colour. The fruit is a woody capsule. Taxonomy and naming The genus was first described in 1862 by the Victorian government botanist, Ferdinand von Mueller in '' Fragmenta Phytographiae Australiae''. The first species he described was '' Phymatocarpus porphyrocephalus''. The name ''Phymatocarpus'' is derived from the Ancient Greek ''phymatos'' (plu ...

Eremaea (plant)
''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'' (as ''Metrosideros 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. Description Plants in the genus ''Eremaea'' are shrubs or small trees with small leaves that are arranged alternately on the stem and are dotted with oil glands. The flowers have both male and female parts and are solitary or in clusters of two or three on the ends of the branches. There are 5 sepals, and 5 petals which fall off as the flower matures. There are many stamens, all longer than the petals and usually arranged in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosid Tribes
The rosids are members of a large clade (monophyletic group) of flowering plants, containing about 70,000 species, more than a quarter of all angiosperms. The clade is divided into 16 to 20 orders, depending upon circumscription and classification. These orders, in turn, together comprise about 140 families. Fossil rosids are known from the Cretaceous period. Molecular clock estimates indicate that the rosids originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago. Today's forests are highly dominated by rosid species, which in turn helped with diversification in many other living lineages. Additionally, rosid herbs and shrubs are also a significant part of arctic/alpine, temperate floras, aquatics, desert plants, and parasites. Name The name is based upon the name "Rosidae", which had usually been understood to be a subclass. In 1967, Armen Takhtajan showed that the correct basis for the name "Rosidae" is a description of a group of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
