Acacia ommatosperma (Pedley) Pedley

Austrobaileya 3(2): 216 (1990):.

Acacia ommatosperma is a shrub of the genus Acacia and the subgenus Plurinerves that is endemic to an area of north western Australia.


The shrub or small tree has weeping branches with glabrous angular branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The glabrous and leathery phyllodes have a narrowly oblong-oblanceolate shape and are incurved with a length of 9.5 to 12.5 cm (3.7 to 4.9 in) and a width of 7 to 14 mm (0.28 to 0.55 in) have three to five main nerves.[1] When it blooms it produces simple inflorescences that occur singly or in pairs in the axils with sperical flower-heads containing 25 to 30 yellow flowers. The thinly leathery and glabrous seed pods that form after flowering have a linear shape but are raised over and consticted between the seeds. The pods are up to 10 cm (3.9 in) in length and have a width of 6 to 8 mm (0.24 to 0.31 in) and contain dull dark brown seeds.[1]

The species was first formally described by the botanist Leslie Pedley in 1987 as Racosperma ommatospermum. It was transferred to genus Acacia in 1990 as Acacia ommatosperma.[2]

The shrub has a limited range in far north Queensland on the Cape York Peninsula around Weipa where it grows in gravelly ironstone soils.[1]
