Acacia obovata is a shrub belonging to the genus Acacia and the subgenus Phyllodineae that is endemic to south western Australia.
The erect dense shrub typically grows to a height of 0.3 to 0.6 metres (1.0 to 2.0 ft). [1] It is often has multiple slender stems and has a woody rootstock with hairy branchlets and narrowly triangular stipules with a length of 1.5 to 4 mm (0.059 to 0.157 in). It has green elliptic to broadly elliptic or obovate shaped phyllodes with a length of 1.5 to 5 cm (0.59 to 1.97 in) and a width of 1 to 2.5 cm (0.39 to 0.98 in) and prominent midrib and marginal nerves. [2] It blooms from March to September and produces white-cream-yellow flowers. [1] The inflorescences occur singly with spherical flower-heads containing five to nine loosely packed yellow to white coloured flowers that dry to an orange colour. The woody brown seed pods that form after flowering have a linear shape but can be spirally twisted when young. The pods have a length of around 11 cm (4.3 in) and a width of 5 to 6 mm (0.20 to 0.24 in) to 11 cm long, 5–6 mm wide, coriaceous-crustaceous to subwoody, glabrous; margins thick and contain glossy dark brown seeds with an oblong to elliptic shape. [2]
The species was first formally described by the botanist George Bentham in 1842 as a part of William Jackson Hookers' work Notes on Mimoseae, with a synopsis of species as published in the London Journal of Botany. It was reclassified as Racosperma obovatum by Leslie Pedley in 2003 then transferred back to genus Acacia in 2006. [3]
It is native to a scattered area along the west coast in the South West, Peel and Wheatbelt regions of Western Australia where it grows in lateritic soils. [1] It is found as far north as Jurien Bay with a disjunct distribution south through parts of the Darling Range down to around Augusta where it is often a part of Eucalyptus marginata and Corymbia calophylla forest communities and less frequently in low open heath lands.
