01Description
Dodonaea triangularis is a spreading, dioecious or rarely polygamodioecious shrub that typically grows to a height of up to 3 m (9.8 ft). Its leaves are simple, usually 12-35 mm (0.47-1.38 in) long and 6-30 mm (0.24-1.18 in) wide on a petiole 1-3 mm (0.039-0.118 in) long, usually egg-shaped or lance-shaped with the narrower end towards the base, and usually with three teeth or lobes on the end. The flowers are arranged in axils in cymes of 3 to 6, sometimes on the ends of branches, each flower on a pedicel 3.5-10 mm (0.14-0.39 in) long. The flowers usually have four lance-shaped sepals 1.2-3 mm (0.047-0.118 in) long and 6 to 8 stamens, and a ovary densely covered with soft hairs. The fruit is a three- or four-angled, more or less spherical or egg-shaped capsule, mostly 6-9 mm (0.24-0.35 in) long and 8.5-11.5 mm (0.33-0.45 in) wide, with leathery or crusty lobes 1-2 mm (0.039-0.079 in) wide.
