Acacia ixodes, commonly known as motherumbung, [1] is a shrub belonging to the genus Acacia and the subgenus Phyllodineae that is native to parts of eastern Australia.
The shrub typically grows to a height of 2 to 7 m (6 ft 7 in to 23 ft 0 in) and has an erect and spreading habit. It has glabrous and resionous branchlets that are angled or flattened towards the apices. [2] Like most species of Acacia it has phyllodes rather than true leaves. The narrowly elliptic to linear or linear-oblanceolate shaped glabrous to resinous phyllodes are straight to slightly curved with a length of 2.5 to 5 cm (0.98 to 1.97 in) and a width of 2 to 5 mm (0.079 to 0.197 in) and has a prominent midvein with faint lateral veins. It produces yellow flowers between August and November. The simple inflorescences occur singly in the axils and have spherical to ovoid shaped flower-heads with a diameter of 4.5 to 7 mm (0.18 to 0.28 in) containing 20 to 30 bright yellow flowers. [2]
The species was first formally described by the botanist Leslie Pedley in 1980 as part of the work A revision of Acacia Mill. in Queensland as published in the journal Austrobaileya . It was reclassified as Racosperma ixodes by Pedley in 1987 then transferred back to genus Acacia in 2001. The only other synonym is Acacia gnidium var. latifolia. [3] The specific epithet is a reference to the sticky nature of new shoots and immature phyllodes. [2]
The shrub has a wide distribution through central New South Wales extending into Queensland. In New South Wales the bulk of the population is situated between Dubbo to around Gilgandra and Mendooran [2]
