Sclerolaena Densiflora
''Sclerolaena densiflora'' is a species of flowering plant in the family Amaranthaceae, native to Western Australia. It was first described in 1904 by William Vincent Fitzgerald as ''Bassia densiflora'', but was transferred to the genus, ''Sclerolaena'' in 1978 by Andrew John Scott. It is found in the central and northern deserts of Western Australia, and also in the Northern Territory where it is considered to be "near threatened". Description This chenopod is an erect perennial, growing to 30 cm high, which is covered all over with long soft silky hairs. The fleshy linear leaves are 10–20 mm long. The flowers are solitary but cluster at the apex of the branches. There are 5 stamens. The tube is a short inverse cone 1–1.5 mm high, with a square, truncated apex. There are five spines in a 3+2 arrangement, which are positioned at the corners of apex, with one pair close together and often appearing to be one spine.

Amaranthaceae
Amaranthaceae is a family of flowering plants commonly known as the amaranth family, in reference to its type genus '' Amaranthus''. It includes the former goosefoot family Chenopodiaceae and contains about 165 genera and 2,040 species, making it the most species-rich lineage within its parent order, Caryophyllales. Description Vegetative characters Most species in the Amaranthaceae are annual or perennial herbs or subshrubs; others are shrubs; very few species are vines or trees. Some species are succulent. Many species have stems with thickened nodes. The wood of the perennial stem has a typical "anomalous" secondary growth; only in subfamily Polycnemoideae is secondary growth normal. The leaves are simple and mostly alternate, sometimes opposite. They never possess stipules. They are flat or terete, and their shape is extremely variable, with entire or toothed margins. In some species, the leaves are reduced to minute scales. In most cases, neither basal nor terminal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories.

William Vincent Fitzgerald
William Vincent Fitzgerald, (21 July 1867 – 6 August 1929) was an Australian botanist. He described five genera and about 210 species of plants from Western Australia, including 33 ''Acacia'' and several ''Eucalyptus'' species. He also collected for other botanists such as Ferdinand von Mueller and Joseph Maiden, and was known through his work on orchids. '' Eucalyptus fitzgeraldii'' was named for him by William Blakely. Fitzgerald was born on the goldfields in north-eastern Tasmania and at the age of 16 was training for a career in mining, but by the time he was in his early 20s he was corresponding with, and sending plant specimens to Mueller. In 1903 he was a member of Western Australian Royal Commission on Forests, and the following year chairman of the Forests Advisory Board of Western Australia. In that year he described 23 ''Acacia'' species, mostly from the south-west of Western Australia, in the first edition of ''Journal of the West Australian Natural History Soci ...

Northern Territory
The Northern Territory (commonly abbreviated as NT; formally the Northern Territory of Australia) is an Australian territory in the central and central northern regions of Australia. The Northern Territory shares its borders with Western Australia to the west ( 129th meridian east), South Australia to the south ( 26th parallel south), and Queensland to the east ( 138th meridian east). To the north, the territory looks out to the Timor Sea, the Arafura Sea and the Gulf of Carpentaria, including Western New Guinea and other islands of the Indonesian archipelago. The NT covers , making it the third-largest Australian federal division, and the 11th-largest country subdivision in the world. It is sparsely populated, with a population of only 249,000 – fewer than half as many people as in Tasmania. The largest population center is the capital city of Darwin. The archaeological history of the Northern Territory may have begun more than 60,000 years ago when humans first se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemic Flora Of 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] |

Flora Of Western Australia
The flora of Western Australia comprises 10,551 published native vascular plant species and a further 1,131 unpublished species. They occur within 1,543 genera from 211 families; there are also 1,317 naturalised alien or invasive plant species more commonly known as weeds. There are an estimated 150,000 cryptogam species or nonvascular plants which include lichens, and fungi although only 1,786 species have been published, with 948 algae and 672 lichen the majority. History Indigenous Australians have a long history with the flora of Western Australia. They have for over 50,000 years obtained detailed information on most plants. The information includes its uses as sources for food, shelter, tools and medicine. As Indigenous Australians passed the knowledge along orally or by example, most of this information has been lost, along many of the names they gave the flora. It was not until Europeans started to explore Western Australia that systematic written details of the flora commen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1904
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the abil ...
