Description
Dodonaea aptera is a dioecious, erect or spreading shrub that typically grows to a height of up to {{cvt|3.5|m}}. Its leaves are simple, usually elliptic, {{cvt|22–60|mm}} long and {{cvt|10–32|mm}} wide on a petiole {{cvt|4–10.5|mm}} long. The flowers are borne on the ends of branches in cymes or panicles, each flower on a pedicel {{cvt|3–7|mm}} long, with four lance-shaped sepals {{cvt|2.5–3|mm}} long, but that fall off as the flowers open. There are eight stamens and a glabrous ovary. Flowering mainly occurs from April to July, and the fruit is a more or less spherical, egg-shaped or broadly oblong capsule, {{cvt|5–6|mm}} long and {{cvt|6–7|mm}} wide, with lobe-like wings {{cvt|0.5–1|mm}} wide.{{cite web |last1=West |first1=Judith Gay |title=Dodonaea aptera |url=https://profiles.ala.org.au/opus/foa/profile/Dodonaea%20aptera |publisher=Flora of Australia.
