Panicum Effusum
''Panicum effusum'', commonly known as hairy panic, is a grass native to inland Australia. It occurs in every mainland state, as well as New Guinea. In dry conditions, the fast-growing grass can become a tumbleweed. Description Hairy panic is a perennial grass that reaches high. The leaves have tubercle-based hairs and are up to long by wide. The seed spikes are typically long, with the spikelets long. Taxonomy Prolific Scottish botanist Robert Brown described ''Panicum effusum'' in his 1810 work ''Prodromus Florae Novae Hollandiae et Insulae Van Diemen''. It still bears its original name. Ferdinand von Mueller described ''Panicum convallium'', which he recorded from the banks of the Torrens and Gawler Rivers, on the Murray River and along the Flinders Ranges, in 1855. Common names include branched panic, hairy panic, effuse panic, native millet and poison panic. Distribution and habitat Found across Australia, particularly in the east and Papua New Guinea, hairy panic o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Brown (botanist, Born 1773)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose, Scotland on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a ...

Paddock
A paddock is a small enclosure for horses. In the United Kingdom, this term also applies to a field for a general automobile racing competition, particularly Formula 1. Description The most common design provides an area for exercise and is often situated near the stables. Larger paddocks may have grass maintained in them, but many are dirt or a similar natural surface. In those cases drainage and a top layer of sand are often used to keep a suitable surface in the paddock. In the Western United States, American West, such an enclosure is often called a corral, and may be used to contain cattle or horses, occasionally other livestock. The word paddock is also used to describe other small, fenced areas that hold horses, such as a saddling paddock at a racetrack, the area where race horses are saddled before a horse race. Horse breeders may let stallions loose in a paddock or field with mares that they would like the stallion to impregnate. This allows the most natural form of mat ...

Flora Of Western Australia
The flora of Western Australia comprises 10,842 published native vascular plant species and a further 1,030 unpublished species. They occur within 1,543 genus, genera from 211 Family (biology), families; there are also 1,335 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 de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of South Australia
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms '' gut flora'' or '' skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) ...

Poales Of Australia
The Poales are a large order of flowering plants in the monocotyledons, and includes families of plants such as the grasses, bromeliads, rushes and sedges. 14 plant families are currently recognized by botanists to be part of Poales. Description The flowers are typically small, enclosed by bracts, and arranged in inflorescences (except in three species of the genus '' Mayaca'', which possess very reduced, one-flowered inflorescences). The flowers of many species are wind pollinated; the seeds usually contain starch. Taxonomy The APG IV system (2016) accepts the order within a monocot clade called commelinids, with 14 families.Huijun Wang, Zhigang Wu, Tao Li, Jindong Zhao, Phylogenomics resolves the backbone of Poales and identifies signals of hybridization and polyploidy, ''Molecular Phylogenetics and Evolution'', Volume 200, 2024, 108184, ISSN 1055-7903, https://doi.org/10.1016/j.ympev.2024.108184.

Panicum
''Panicum'' (panicgrass) is a large genus of about 250 species of Poaceae, grasses native throughout the tropical regions of the world, with a few species extending into the northern temperate zone. They are often large, Annual plant, annual or Perennial plant, perennial grasses, growing to tall. The flowers are produced in a well-developed panicle often up to in length with numerous seeds, which are long and broad. The fruits are developed from a two-flowered spikelet. Only the upper floret of each spikelet is fertile; the lower floret is sterile or staminate. Both glumes are present and well developed. Australia has 29 native and 9 introduced species of ''Panicum''. Well-known species include ''Panicum miliaceum, P. miliaceum'' (proso millet) and ''Panicum virgatum, P. virgatum'' (switchgrass). Phylogenetic studies found the genus as previously circumscribed was polyphyletic, and several species have been reassigned to other genera. Most species in section ''Stolonifera'' ...

Kali Tragus
''Salsola tragus'', often known by its synonym is a species of flowering plant in the family Amaranthaceae. It is known by various common names such as prickly Russian thistle, windwitch, or common saltwort. It is widely known simply as tumbleweed because, in many regions of the United States, it is the most common and most conspicuous plant species that produces tumbleweeds. Informally, it may be known as "'Kali'' or ''Salsola": the latter being its restored genus, containing 54 other species, into which the obsolete genus ''Kali'' has been subsumed. For a brief phase during its youth, it may be grazed but afterward becomes too spiny and woody to be edible to most wildlife and livestock (if it is not processed first). Mature specimens are often more than a meter in diameter. As its fruits mature, the diaspore of the plant dies, dries, hardens, and detaches from its root. This detached anatomical part of is colloquially called "tumbleweed" (although there are many other plant s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
