Description

Dodonaea filifolia is a dioecious erect shrub or small tree that typically grows to a height of up to 5 m (16 ft). Its leaves are simple, sessile, linear to thread-like, 55–105 mm (2.2–4.1 in) long, about 1 mm (0.039 in) wide and glabrous. The flowers are borne in five- or six-flowered cymes on the ends of branches, each flower on a pedicel 3.3–7.5 mm (0.13–0.30 in) long, with eight stamens. The sepals are lance-shaped, 1.2–1.5 mm (0.047–0.059 in) long but fall off as the flowers develop and the ovary is usually glabrous. The fruit is a four-winged capsule 9.5–12.5 mm (0.37–0.49 in) long and 11.5–13 mm (0.45–0.51 in) wide, the wings membranous or sometimes leathery, 2.5–4 mm (0.098–0.157 in) wide. [3]
