Ptilotus is a genus of approximately 120 species of annual and perennial herbs and shrubs in the family Amaranthaceae. All species are native to mainland Australia, [5] [6] [7] although one species, Ptilotus spathulatus (R.Br.) Poir., also occurs in Tasmania and another, Ptilotus conicus R.Br., in Malesia on the islands of Flores and Timor. [8] Most of the diversity is in Western Australia, particularly in the Pilbara. [5] [8] [9] Common names for species in this genus include mulla mulla, foxtails, pussy tails and lamb's tails. The genus was first formally described by botanist Robert Brown in Prodromus Florae Novae Hollandiae in 1810. [1] [5] In family-level phylogenetic studies, Ptilotus has been placed within a clade informally known as the 'aervoids'. [10] It has been resolved as monophyletic and is closely related to Aerva Forssk. [5] [11] An interactive key to the species of Ptilotus is available at KeyBase. [12]

<span class="mw-page-title-main">Amaranthoideae</span> Subfamily of flowering plants

The Amaranthoideae are a subfamily of the Amaranthaceae. The stamens have anthers with two lobes (locules) and four pollen sacs. The main distribution of the subfamily is in tropical America, in tropical and Southern Africa, and in Australia.

<i>Gomphrena</i> Genus of flowering plants

Gomphrena is a genus of plants in the family Amaranthaceae. They are known as the globe amaranths.

<i>Lechenaultia</i> Genus of plants

Lechenaultia is a genus of flowering plants in the family Goodeniaceae, the species native to Australia with one species also occurring in New Guinea. Plants in the genus Lechenaultia are glabrous shrubs or herbs with needle-shaped leaves, more or less sessile flowers with five sepals and five blue, white, or yellow and red petals in two unequal lobes, the fruit an elongated capsule.

<i>Dampiera</i> Genus of flowering plants

Dampiera is a genus of about 70 species of flowering plants in the family Goodeniaceae, all of which are endemic to Australia. Plants in the genus Dampiera are subshrubs or herbs with sessile leaves, flowers with five small sepals and blue, violet or pink, rarely white, two-lipped flowers.

<i>Ptilotus macrocephalus</i> Species of plant

Ptilotus macrocephalus is a native Australian perennial herb growing up to 50 centimetres (20 in) high. The species was originally described as Trichinium macrocephalum by Robert Brown in 1810 based on specimens from Victoria, Australia. In 1816, it was first transferred to the genus Ptilotus by Jean Louis Marie Poiret. While once considered distributed throughout most of the Australian mainland, current research limits the distribution of P. macrocephalus to south-eastern Australia, mostly in south-eastern South Australia, Victoria and New South Wales. A study by Hammer et al. (2019) determined that specimens previously identified as P. macrocephalus are morphologically and ecologically distinct species, the now named Ptilotus xerophilusT.Hammer & R.W.Davis and Ptilotus psilorhachisT.Hammer & R.W.Davis.
