Common name
Whilst the term “mulla mulla” is used to describe many of the species, they are sometimes called “pussy tails’ because of the appearance of the flower spikes. Other names include pussy tails and lamb’s tail.

The different Aboriginal tribes have their own names in langugage for the different Ptilotus spp.1

Plants are an integral part of Aboriginal culture. As well as bush tucker and bush medicine, certain desert plants are regarded as sex totems. The pink flowered mulla-mullas (Ptilotus spp.) is representative of the male, whilst several plants with milky sap represent the female.2
