Contents

Ptilotus pyramidatus , the pyramid mulla mulla, [5] is a small white herb in the family Amaranthaceae. [1]

Ptilotus pyramidatus was first described in 1849 by Alfred Moquin-Tandon as Trichinium pyramidatum, [6] [7] but was redescribed in 1868 by Ferdinand von Mueller when he allocated it to the genus, Ptilotus . [2] [3]

Under Western Australian conservation legislation it has been declared "rare". [1]

Mueller's description

Ptilotus pyramidatus (Trichinium pyramidatum, Moq. in Cand. Prodr. xiii. div. ii. 288) mihi adest solum e collectione Drummondi sub 221 et 99. Folia suprema saepe ovata et perbrevi-petiolata. Spicae passim binatae. Stamina inaequilonga; unum alterumve sterile. Stylus glaber, circiter lineam metiens. Villi minutissime denticulati; articuli eorum plerique suo diametro aliquoties longiores. [3]

(translation)

I am here solely because of Drummond's specimens: 99 and 221 (PERTH 782289, MEL 0235383A collected in 1845). The topmost leaves are nearly always ovate and shortly petiolate. The spikes are randomly paired. The stamens are unequal, with one or two being sterile. The style is smooth and is about 1/12 inch long. The hairs (villi) are very minutely toothed, and their segments for the most part are several times the length of their diameter.

A later description of the plant (as P. christineae) is given in Davis & Tauss (2011). [8]

Banksia prionophylla is a shrub endemic to Western Australia. Known only from a single population of around 70 plants in a remote part of Western Australia, it is considered rare but not endangered. It was first discovered in 2001, and published under the genus Dryandra in 2005, before being transferred into Banksia in 2007.

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

Maireana is a genus of around 57 species of perennial shrubs and herbs in the family Amaranthaceae which are endemic to Australia. Species in this genus were formerly classified within the genus Kochia. The genus was described in 1840 by the botanist, Moquin-Tandon and named to honour Joseph François Maire (1780-1867), an amateur botanist who befriended him during the author's first visit to Paris in 1834.

<i>Ptilotus</i> Family of shrubs

Ptilotus R.Br. 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, 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. Most of the diversity is in Western Australia, particularly in the Pilbara. 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. In family-level phylogenetic studies, Ptilotus has been placed within a clade informally known as the 'aervoids'. It has been resolved as monophyletic and is closely related to Aerva Forssk. An interactive key to the species of Ptilotus is available at KeyBase.

<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.
