Description
Dodonaea caespitosa is dioecious, spreading, compact shrub that typically grows to a height of up to 50 cm (20 in). The leaves are sessile, simple, linear, glabrous, 2–10 mm (0.079–0.394 in) long, about 1 mm (0.039 in) wide with the end curved downwards and the edges rolled under. There are up to four irregular teeth on the outer part of the leaves. The flowers more or less sessile, borne singly in leaf axils, with three egg-shaped sepals 1.5–2.3 mm (0.059–0.091 in) long, but that fall off as the flowers open. There are usually six stamens and the ovary is glabrous. The fruit is a three-angled, spherical capsule 4.5–6 mm (0.18–0.24 in) long and 5–9 mm (0.20–0.35 in) wide, with horn-like appendages 1–3 mm (0.039–0.118 in) wide near the tip of the capsule.[2][3]
