Dodonaea pachyneura is an erect dioecious shrub that typically grows to a height of up to 4 m (13 ft). Its leaves are simple, linear or lance-shaped with the narrower end towards the base, 20–60 mm (0.79–2.36 in) long and 2–7 mm (0.079–0.276 in) wide and sessile or tapering to a petiole 3–12 mm (0.12–0.47 in) long. The flowers are arranged a few-flowered cyme, each flower on a pedicel 1.5–4 mm (0.059–0.157 in) long, usually with three lance-shaped to egg-shaped sepals, 1.2–1.7 mm (0.047–0.067 in) long and usually six stamens. The ovary is glabrous. The fruit is usually a three-winged, egg-shaped capsule 6–9 mm (0.24–0.35 in) long and 11–16 mm (0.43–0.63 in) wide with membranous wings 2.5–5.5 mm (0.098–0.217 in) wide. [2]
