text: # Ptilotus pyramidatus
  
  Ptilotus pyramidatus , the pyramid mulla mulla, is a small white herb in the family Amaranthaceae.
  
  Ptilotus pyramidatus was first described in 1849 by Alfred Moquin-Tandon as Trichinium pyramidatum, but was redescribed in 1868 by Ferdinand von Mueller when he allocated it to the genus, Ptilotus.
  
  Under Western Australian conservation legislation it has been declared "rare".
  
  ## 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.
  
  (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).
