Plants of Borneo

Cluster fig

Ficus racemosa

Cluster fig produces its figs on woody parts of the tree, with flowers hidden inside the rounded syconia. Male and female flowers occur within the same species’ monoecious reproductive system.

Flowers, fruits & reproduction

Cluster fig produces its figs on woody parts of the tree, with flowers hidden inside the rounded syconia. Male and female flowers occur within the same species’ monoecious reproductive system. The documented pollinator is the fig wasp Ceratosolen fusciceps. A fig is therefore more than a container of seeds: it is also the place where a very small insect completes part of its life cycle.

Life in the ecosystem

This mutual dependence is a useful contrast with Ficus fistulosa, whose male and female trees are separate and whose recorded wasps differ. Forest fig diversity includes differences invisible from the outside: flower arrangement, insect partners and timing of reproduction. General statements that “figs feed animals” do not identify the particular animal or establish a Bornean observation for this species.

Ecological relationships

Along the Kinabatangan riverbanks, direct observations found this fig to be the most frequently eaten plant in the study of proboscis monkeys. Its leaves accounted for a large share of recorded leaf feeding; the result describes this riverside sample, not every group across Borneo.
