About
Acacia macraneura, commonly known as big pod mulga or big mac mulga, is a species of flowering plant in the family Fabaceae and is endemic to arid areas of Western Australia. It is a spreading, multi-stemmed shrub, sometimes an inverted cone-shape shrub, with stems and branches somewhat crooked, curved to s-shaped or winding phyllodes, spikes of yellow flowers, and oblong to narrowly oblong, thinly leathery pods slightly to obviously rounded over the seeds.
Where it grows
Big pod mulga grows in clay or loam associated with calcrete, often on floodplains or in shallow drainage systems in mulga with a ground cover, including grasses. It is confined to the Carnarvon, Gascoyne, Great Sandy Desert, Little Sandy Desert, Murchison and Pilbara bioregions of Western Australia. It has a scattered distribution from around Mount Magnet to near Leonora and the Rudall River catchment. There is also a population on Mount Agnes in South Australia, near the border with Western Australia.
