Melaleuca Punicea
''Melaleuca punicea'' is a plant in the myrtle family, Myrtaceae, and is endemic to the Northern Territory in Australia. Some of the characteristics of this species make it difficult to classify at the genus level. After it was originally described in 1984 as ''Melaleuca punicea'', it was transferred in 1986 to the genus ''Regelia'' (as ''Regelia punicea'') but it did not fit well in that genus either. In 1999 it was transferred again to a new genus ''Petraeomyrtus'' as ''P. punicea''. Subsequent molecular studies, especially of chloroplast DNA have suggested that it is best placed in ''Melaleuca'' along with others from genera including '' Beaufortia'', ''Callistemon'' and ''Regelia''. Later publications include this species as ''Melaleuca punicea''. Description ''Melaleuca punicea'' is a spreading shrub growing to about tall. Its leaves are long and wide, with no apparent stalk, narrow triangular in shape, and almost crescent shape in cross section. The flowers are bright r ...

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] |
Johannes Conrad Schauer
Johannes Conrad Schauer (16 February 1813 – 24 October 1848) was a botanist interested in Spermatophytes. He was born in Frankfurt am Main and attended the gymnasium of Mainz from 1825 to 1837. For the next three years he worked at the Hofgarten of Würzburg. Schauer then gained a position as assistant at the botanical garden at Bonn where he worked until 1832 when he was placed in charge of the botanic garden in Breslau, (now Wrocław in Poland) with C.G. Nees. He gained the degree of Doctor of Philosophy at the University of Erlangen-Nuremberg 1835 and was appointed professor of botany at the University of Greifswald from 1843 until his death in 1848. Although he never visited Australia, many Australian botanists and plant collectors sent him plant specimens, especially eucalypts and other members of the myrtle family, Myrtaceae. For example, when Allan Cunningham died in 1839, Schauer received many botanical specimens from the executor of Cunningham's estate, , including ...

Eduard August Von Regel
Eduard August von Regel (sometimes Edward von Regel or Edward de Regel or Édouard von Regel), Russian: Эдуард Август Фон Регель; (born 13 August 1815 in Gotha; died 15 April 1892 in St. Petersburg) was a German horticulturalist and botanist. He ended his career serving as the Director of the Russian Imperial Botanical Garden of St. Petersburg. As a result of naturalists and explorers sending back biological collections, Regel was able to describe and name many previously unknown species from frontiers around the world. History Regel was the son of the teacher and garrison-preacher Ludwig A. Regel. Already as a child he liked growing fruits and learnt to prune apple trees from a gardener of his grandfather Döring and cultivated the garden of his parents. He visited the Gymnasium at Gotha but left without Abitur Regel earned a degree from the University of Bonn. At 15, Regel began his career as an apprentice at the Royal Garden Limonaia in Gotha in 1830 ... [...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 ...

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] |
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 ...

Botanist
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, med ...

Ovary (botany)
In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals. The pistil may be made up of one carpel or of several fused carpels (e.g. dicarpel or tricarpel), and therefore the ovary can contain part of one carpel or parts of several fused carpels. Above the ovary is the style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary, and, for each individual pollen grain, to fertilize one individual ovule. Some wind pollinated flowers have much reduced and modified ovaries. Fruits A fruit is the mature, ripened ovary of a flower following double fertilization in an angiosperm. Because gymnosperms do not have an ovary but reproduce through double fertilization of unprotected ovules, they produce naked seeds that do not ...
