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

Description[edit]

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 constricted 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]

Taxonomy[edit]

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]

Distribution[edit]

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]
