Common along the margin of the lake and occasional in the young forest. Flowers and fruits may be seen throughout the year. Flowers mostly in the middle to late dry and early rainy seasons (February to May), with most fruits maturing in the middle to late rainy season, especially in September and October. A second flush of flowering may occur in October, with the fruits maturing in January and February.

The fruit and bark of this species are poisonous (Allen, 1956; Blohm, 1962). The species is an obligate outcrosser, since it is self-incompatible (Bawa, 1974).
