Ptilotus Nobilis
''Ptilotus nobilis'', commonly known as yellow tails, is an annual or short-lived perennial herb of the family Amaranthaceae. It is found in arid regions of South Australia, southern and eastern Northern Territory, western Queensland and western New South Wales. The species was first formally described by English botanist John Lindley in Thomas Mitchell's ''Three Expeditions into the interior of Eastern Australia'' in 1838. Lindley gave it the name ''Trichinium nobile'' Lindl. The species was transferred to the genus'' Ptilotus'' in 1868 by Victorian Government Botanist Ferdinand von Mueller in the sixth volume of his ''Fragmenta Phytographiae Australiae''. A 2007 molecular study of the ITS (internal transcribed spacer) nrDNA a few populations of ''P. nobilis'' var. ''nobilis'' and ''Ptilotus exaltatus'' var. ''exaltatus'' in Queensland found a very close relationship between the two using a neighbour-joining analysis. ''Ptilotus exaltatus'' var. ''exaltatus'' was subsequently ...

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 ...

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 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 aggregations of leav ...
