Barbara Lynette Rye
Barbara Lynette Rye is an Australian botanist born in 1952. Barbara Rye has been associated with the Western Australian Herbarium, where her work as a taxonomist has been the source of many new descriptions of plants. The number of taxa recorded as described by women authors is historically very low, of the terrestrial plant species this amount is around three percent, yet in analysis published in 2019 Rye is amongst the ten most prolific women taxonomists. Born in Perth, Western Australia, she spent her childhood investigating the local flora and fauna of the Southwest Australia region, a biodiversity hotspot, and later began studies at the University of Western Australia. Barbara Rye entered the fields of zoology and botany, taking a special interest in genetics and evolutionary biology. The first description of a new species was a '' Darwinia'', a genus of the family Myrtaceae that Rye investigated for her doctoral thesis, separating '' Darwinia capitellata'' from a more widel ...

Anthers
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 ''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'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea''). The androecium in var ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosids Of Western Australia
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 ... [...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 ...

Endemic Flora Of Western Australia
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mallee Bioregion
Mallee, also known as Roe Botanical District, is a biogeographic region in southern Western Australia. Located between the Esperance Plains, Avon Wheatbelt and Coolgardie bioregions, it has a low, gently undulating topography, a semi-arid mediterranean climate, and extensive ''Eucalyptus'' mallee vegetation. It has an area of . About half of the region has been cleared for intensive agriculture. Recognised as a region under the Interim Biogeographic Regionalisation for Australia (IBRA), it was first defined by John Stanley Beard in 1980. Geography and geology The Mallee region has a complex shape with tortuous boundaries, but may be roughly approximated as the triangular area south of a line from Bruce Rock to Eyre, but not within 40 kilometres (25 mi) of the south coast, except at its eastern limits. It has an area of about 79000 square kilometres (31000 mi²), making it about a quarter of the South West Botanic Province, 3% of the state, and 1% of Australia. It ...

Coolgardie Bioregion
Coolgardie is an Australian bioregion consisting of an area of low hills and plains of infertile sandy soil in Western Australia. It has an area of . It includes much of the Great Western Woodlands. Location and description This is a transition zone between the Mediterranean climate of Australia's south-west coast and the country's dry interior. The poor soil makes it unsuitable for agriculture but Coolgardie has been a gold and nickel mining area. It is bounded on the north by the arid Murchison bioregion, characterised by open Mulga woodlands and steppe. The low shrublands of the arid Nullarbor Plain lie to the east. The Mallee bioregion adjoins Coolgardie on the south. The Avon Wheatbelt bioregion is to the west. The Coolgardie bioregion, together with the coastal Hampton bioregion to the southeast, constitute the Coolgardie woodlands ecoregion defined by the World Wildlife Fund.

Avon Wheatbelt
The Avon Wheatbelt is a bioregion in Western Australia. It has an area of . It is considered part of the larger Southwest Australia savanna ecoregion. Geography The Avon Wheatbelt bioregion is mostly a gently undulating landscape with low relief. It lies on the Yilgarn Craton, an ancient block of crystalline rock, which was uplifted in the Tertiary and dissected by rivers. The craton is overlain by laterite deposits, which in places have decomposed into yellow sandplains, particularly on low hills. Steep-sided erosional gullies, known as breakaways, are common.

Lake King
Lake King is a town in the eastern Wheatbelt region of Western Australia, from Perth along State Route 40 between Kelmscott and Ravensthorpe. As of 2016, the town had a population of 95. The 2011 census recorded both the population of the town and the surrounding area for a population of 332. Lake King is named after a nearby lake which in turn was named after the Surveyor General of Western Australia, Henry Sandford King, by Marshall Fox, District Surveyor (Narrogin). In 1926, following completion of an initial land classification survey of the Lake King district that defined 230,000 acres as suitable for settlement, a large official inspection party was led by Surveyor General John Percy Camm, Sydney Stubbs ( MLA Wagin), Edwin Wilkie Corboy (MLA Yilgan), and James Cornell ( MLC South Province). The area was surveyed and access roads built during 1927, and land released in 1928 at prices from 4/6 to 16/- per acre. The town struggled through the depression but thrived in ...

Hyden, Western Australia
The town of Hyden is located east-southeast of Perth, Western Australia in the Shire of Kondinin. Hyden is home to Wave Rock, Mulka's Cave and Hippos Yawn, all popular local tourist attractions. The traditional owners of the area are the Aboriginal Australian group the Njakinjaki people, who have inhabited the region for thousands of years. The many granite outcrops, land formations, waterways as well as flora and fauna are still culturally significant to them. Sandalwood cutters were thought to be the earliest European visitors in the area. The land in the surrounding area was opened up for agriculture in the 1920s. A railway was built between Kondinin and Hyden Rock in 1930. The townsite was gazetted in 1932 following demand for land around the railway terminus. The first wheat crop was harvested in Hyden in 1927. The Hyden Progress Association was established prior to 1931 when the town was home to about 100 settlers. In 1931 the town had another large wheat crop, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
