Acacia dodonaeifolia, commonly known as sticky wattle or hop bush wattle,[2] is a species of flowering plant in the family Fabaceae and is endemic to the south-east of continental Australia. It is a sticky glabrous shrub or tree narrowly elliptic phyllodes, spherical heads of bright yellow flowers and linear, thinly leathery pods.
Acacia dodonaeifolia is a sticky, glabrous shrub or tree that typically grows to a height of 2–6m (6ft 7in– 19ft 8in) and has varnished branchlets when young. The phyllodes are usually narrowly elliptic, 40–80mm (1.6–3.1in) long and 5–11mm (0.20–0.43in) wide, glabrous, slightly roughened with prominent midrib with two or three glands up to 5mm (0.20in) above the base of the phyllode. The flowers are borne in two or three spherical heads in axils on peduncles7–15mm (0.28–0.59in) long, each head with 36 to 46 bright yellow flowers. Flowering occurs between July and November, and the pods are linear, thinly leathery, up to 130mm (5.1in) long, 5–7mm (0.20–0.28in) wide and light brown. The seeds are oblong to elliptic, shiny dark brown, 4.3–5mm (0.17–0.20in) long with a folded aril on the end.[2][3][4][5][6]
Taxonomy
This species was first formally described in 1806 by the Christiaan Hendrik Persoon and given the name Mimosa dodonaeifolia in the his Synopsis plantarum.[7][8] In 1813, Giovanni Battista Balbis transferred the species to Acacia as A. dodonaeifolia.[9] The specific epithet (dodonaeifolia) means having leaves like a dodonaea.[6]
