The flowers of Dodonea angustifolia grow in upper axillary and terminal heads, corymbs, racemes or panicles. These variable clusters become about 1.5 cm long.
The globular flowers have three to eight sepals while there are no petals. A flower becomes about 7 mm in diameter. In a female flower the ovary is two- to four-lobed and the style protrudes; stamens being either sterile or absent. Male flowers have four to eight stamens. The flowers in picture are male, showing thick, incurved anthers inside the spreading sepals.
Flower colour is greenish yellow or tinted reddish as in this photo taken near Oudtshoorn during August. Flowers appear in autumn and winter.
The sexes are represented in different flowers; they may either be separate on different trees (dioecious) or trees may be bisexual (monoecious), having flowers of both sexes (Coates Palgrave, 2002; Schmidt, et al, 2002).
