Description
Dodonaea rigida is an erect, dioecious shrub that typically grows to a height of up to 2 m (6 ft 7 in). Its leaves are simple, sessile, rigid, almost thread-like, sometimes sharply pointed, 34–75 mm (1.3–3.0 in) long, about 1 mm (0.039 in) wide. The flowers are arranged in cymes of three or four in leaf axils, each flower on a pedicel 4.5–7.5 mm (0.18–0.30 in) long, with three or four broadly egg-shaped sepals, 1.4–1.7 mm (0.055–0.067 in) long but that fall off as the flowers develop. The ovary is glabrous and the fruit is a three- or four-winged capsule, 10–15 mm (0.39–0.59 in) long and 14–17 mm (0.55–0.67 in) wide, the wings 4–6.5 mm (0.16–0.26 in) wide and membranous.[2]
