Calothamnus Macrocarpus
''Calothamnus macrocarpus'' is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is an erect shrub with bright red flowers in spring and large, almost spherical fruit. It has a limited distribution near Hopetoun. (In 2014 Craven, Edwards and Cowley proposed that the species be renamed ''Melaleuca macrocarpa''.) Description ''Calothamnus macrocarpus'' is an erect shrub with many branches growing to a height of about . Its leaves are crowded, long, in diameter, cylindrical in shape and taper to a non-prickly point. There are prominent oil glands on the leaves. The flowers are deep red usually in small clusters between the leaves. The petals are long, thin, papery and pink to brown. The stamens are arranged in 5 claw-like bundles usually with 26 to 28 stamens per bundle. Flowering occurs from August to December and is followed by fruits which are woody, almost spherical capsules, in diameter, which are often hidden in the foliage ...

Nuytsia (journal)
''Nuytsia'' is a peer-reviewed scientific journal published by the Western Australian Herbarium. It publishes papers on systematic botany, giving preference to papers related to the flora of Western Australia. Nearly twenty percent of Western Australia's plant taxa have been published in ''Nuytsia''. The journal was established in 1970 and has appeared irregularly since. The editor-in-chief is Kevin Thiele. ''Nuytsia'' is named after the monospecific genus ''Nuytsia'', whose only species is '' Nuytsia floribunda'', the Western Australian Christmas tree. Occasionally, the journal has published special issues, such as an issue in 2007 substantially expanding described species from Western Australia. Publication details The record of the issues published is found at the ''FloraBase ''FloraBase'' is a public access web-based database of the flora of Western Australia. It provides authoritative scientific information on 12,978 taxa, including descriptions, maps, images, conservati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myrtales Of Australia
The Myrtales are an order of flowering plants placed as a sister to the eurosids II clade as of the publishing of the ''Eucalyptus grandis'' genome in June 2014. The APG III system of classification for angiosperms still places it within the eurosids. This finding is corroborated by the placement of the Myrtales in the Malvid clade by the One Thousand Plant Transcriptomes Initiative. The following families are included as of APGIII: * Alzateaceae S. A. Graham * Combretaceae R. Br. ( leadwood family) * Crypteroniaceae A. DC. * Lythraceae J. St.-Hil. ( loosestrife and pomegranate family) * Melastomataceae Juss. (including Memecylaceae DC.) * Myrtaceae Juss. (myrtle family; including Heteropyxidaceae Engl. & Gilg, Psiloxylaceae Croizat) * Onagraceae Juss. (evening primrose and Fuchsia family) * Penaeaceae Sweet ex Guill. (including Oliniaceae Arn., Rhynchocalycaceae L. A. S. Johnson & B. G. Briggs) * Vochysiaceae A. St.-Hil. The Cronquist system gives essentially the same co ...

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] |
Quartzite
Quartzite is a hard, non- foliated metamorphic rock which was originally pure quartz sandstone.Essentials of Geology, 3rd Edition, Stephen Marshak, p 182 Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals. The term ''quartzite'' is also sometimes used for very hard but unmetamorphosed sandstones that are composed of quartz grains thoroughly cemented with additional quartz. Such sedimentary rock has come to be described as orthoquartzite to distinguish it from metamorphic quartzite, which is sometimes called metaquartzite to emphasize its metamorphic origins. Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops. The nearly pure silica conte ...

Esperance Plains
Esperance Plains, also known as Eyre Botanical District, is a biogeographic region in southern Western Australia on the south coast between the Avon Wheatbelt and Hampton bioregions, and bordered to the north by the Mallee region. It is a plain punctuated by granite and quartz outcrops and ranges, with a semi-arid Mediterranean climate and vegetation consisting mostly of mallee-heath and proteaceous scrub. About half of the region has been cleared for intensive agriculture. Recognised as a bioregion under the Interim Biogeographic Regionalisation for Australia (IBRA), it was first defined by John Stanley Beard in 1980. Geography and geology The Esperance Plains may be roughly approximated as the land within of the coast between Albany and Point Culver on the south coast of Western Australia. It has an area of about , making it about 9% of the South West Province, 1% of the state, and 0.3% of Australia. It is bounded to the north by the Mallee region, and to the west by ...

East Mount Barren
East Mount Barren is a quartzite peak of the Barren Range in Fitzgerald River National Park. It was sighted and named by explorer Matthew Flinders on 6 January 1802, together with two other peaks in the range, West Mount Barren and Middle Mount Barren. All were named because of their barren appearance. A walking track ascends in height to the summit which has views of the coast from the Doubtful Islands to Mason Point as well as inland. Plant species that are endemic to East Barren Mountain and its immediate environs include '' Calothamnus macrocarpus'', '' Eucalyptus burdettiana'' (Burdett gum), '' Kunzea similis'' subsp. ''similis'', ''Regelia velutina'' (Barrens regelia) and ''Verticordia pityrhops''. Other species of note include '' Acacia argutifolia'' (East Barrens wattle), ''Adenanthos ellipticus'' (oval-leaf adenanthos), ''Anthocercis fasciculata'', ''Banksia speciosa'' (showy banksia), '' Dampiera deltoidea'', ''Eucalyptus coronata'' (crowned mallee), ''Gonocarpus ...

Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capsule (botany)
In botany a capsule is a type of simple, dry, though rarely fleshy dehiscent fruit produced by many species of angiosperms (flowering plants). Origins and structure The capsule (Latin: ''capsula'', small box) is derived from a compound (multicarpeled) ovary. A capsule is a structure composed of two or more carpels. In (flowering plants), the term locule (or cell) is used to refer to a chamber within the fruit. Depending on the number of locules in the ovary, fruit can be classified as uni-locular (unilocular), bi-locular, tri-locular or multi-locular. The number of locules present in a gynoecium may be equal to or less than the number of carpels. The locules contain the ovules or seeds and are separated by septa. Dehiscence In most cases the capsule is dehiscent, i.e. at maturity, it splits apart (dehisces) to release the seeds within. A few capsules are indehiscent, for example those of ''Adansonia digitata'', ''Alphitonia'', and '' Merciera''. Capsules are often classifie ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Hopetoun, Western Australia
Hopetoun is a town on the south coast of Western Australia in the Shire of Ravensthorpe. Located on Mary Ann Harbour, Hopetoun is south-east from capital city Perth and west of Esperance. History Mary Ann Harbour was named in November 1865 by the sealer James Sale on the cutter ''Mary Ann''. The ''Mary Ann'' was owned by whaling master John Thomas of Cheyne's Beach, east of Albany, who had named it after his eldest daughter. Hopetoun was established in 1900 as the port servicing the Phillips River goldfield, named after the first Governor-General of Australia, John Hope, 7th Earl of Hopetoun. The townsite was gazetted on 9 February 1901. The town became a shipping port for the mining industry, with a jetty built in 1901, the terminus of a railway line between Hopetoun and Ravensthorpe that operated from 1909 to 1935. The port was closed in 1937, with the jetty remaining until its destruction in 1983. Some of the town's electricity is generated by a wind-diesel system. ...
