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 synonymized together with P. nobilis var. nobilis un......read more on Wikipedia.
