The flowers of Celtis africana are unisex, i.e. the sexes are separate on different flowers, but both occur on the same tree. The flowers are small, greenish and fairly inconspicuous, growing from leaf axils near stem tips. Flowering happens in spring.
The fruit, a yellow or brown, ovoid drupe, is more likely to be spotted than the flowers. The timing of the fruit is late spring into summer, a time when fruit eating birds usually feast (Coates Palgrave, 2002; Schmidt, et al, 2002).
