About
Acacia assimilis is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is a dense, spreading, rounded shrub or tree with thread-like, glabrous, green phyllodes, spherical to elliptic or oblong heads of golden or lemon-yellow flowers, and linear pods up to 85 mm (3.3 in) long.
Where it grows
Acacia assimilis is common from Mullewa to Boxwood Hill and east to the Norseman-Scaddan area in the Avon Wheatbelt, Coolgardie, Esperance Plains, Geraldton Sandplains, Mallee, Swan Coastal Plain and Yalgoo bioregions of south-western Western Australia where it is grows on sandplains, in low-lying areas, among granite outcrops and on rocky hills. The southern part of the range is occupied by subsp. atroviridis and the two subspecies overlap in a narrow range, with some collections suggesting that hybridisation is possible.
