Gender and the structure of the inflorescence and flowers of Pappea capensis (Sapindaceae) are investigated in a locality around Pretoria (22–27°S
and 25–32°E). The trees flower over a long period (December to April) and are basically monoecious, starting with male flowers followed by female
flowers towards the end of the flowering period, although some trees may be predominantly male and some predominantly female. The inflorescence is a
reduced thyrse with small flowers. Male flowers have five ephemeral petals, eight stamens and a rudimental pistil. Female flowers comprise a 3-lobed
ovary, a single style and stigma and eight staminodes.
