Alice Springs Flora •
The Rat’s Tail (Dysphania kalpari) is a prostrate decumbent annual (decumbent describes a plant lying along the ground with the extremity curving upwards). From the base of the plant arises several erect slender stems (up to 15 cm long), that are a bright green and deeply lobed. These distinctive inflorescence ‘rat tail’ spikes are the female and bisexual flowers. Germinating after winter rains, they flower from May to September.
A sticky aromatic plant, the leaves are elliptic, deeply undulate / lobed. The plant is strongly scented, a citrus like perfume to some, smelly to others. The seeds that form on the long spikes are small, black and shiny.
The seeds are used as a food source and herbal medicine by local Aboriginal people. Due to the sticky nature of the plant, the seeds remain on the spikes as they mature, until the plant itself dries out. This means that the seeds are harvested much later in the season when the seeds of most other plants are no longer available.
Found growing across Western Australia, Northern Territory, South Australia, New South Wales and Queensland. They usually grow on loam flats and red sand plains and are associated with Mulga (Acacia aneura) country.
Rat’s Tail, Rat-tail, Goosefoot, Green Crumbleweed. In the Utopian Homelands of Central Australia it is known as Alpar.
