Dodonaea hispidula is a species of flowering plant in the family Sapindaceae and is native to tropical northern Australia. It is a shrub with simple, usually clustered, narrowly elliptic or egg-shaped leaves with the narrower end towards the base, flowers arranged singly, in racemes or panicles, and oblong or elliptic capsules with three or four locules.
Dodonaea hispidula is a shrub that typically grows to a height of up to 2m (6ft 7in). Its leaves are simple, usually clustered, narrowly elliptic or egg-shaped with the narrower end towards the base, 15–90mm (0.59–3.54in) long and 8–34mm (0.31–1.34in) wide, on a petiole2–14mm (0.079–0.551in) long. The flowers are arranged singly or in racemes or panicles on the ends of branches or in leaf axils, each flower on a pedicel2–22mm (0.079–0.866in) long. There are five to ten elliptic sepals and 30 to 74 stamens, the ovary oval or heart-shaped, covered with soft hairs with a style5–25mm (0.20–0.98in) long. The fruit is an oval to elliptic capsule with 3 or 4 locules and wings 2–7mm (0.079–0.276in) long and 2–14mm (0.079–0.551in) wide.[2]
Taxonomy
Dodonaea hispidula was first formally described in 1835 by Stephan Endlicher in his Atakta Botanika.[3]

Dodonaea hispidula var. phylloptera(F.Muell.) M.G.Harr.[8] is a shrub up to 2m (6ft 7in) high, the leaves not clustered 40–90mm (1.6–3.5in) long on a petiole 4–14mm (0.16–0.55in) long, six to eight sepals 3–6mm (0.12–0.24in) long, 30 to 52 stamens and the fruit is 8–10mm (0.31–0.39in) long and 12–28mm (0.47–1.10in) wide with wings up to 14mm (0.55in) wide.[9]
