Ficus francisci is an unusual dioecious fig (separate male and female trees ) endemic to Borneo. In Sabah it is rare but widespread including Kipandi Butterfly Farm in the Crocker Range. However F. francisci is locally common in Brunei and N. Sarawak especially at Lambir Hills near Miri where it is the 8th most common fig in the Smithsonian 52 ha forest plot.
The figs grow in cauliferous bunches from the trunk down to ground level and vary in colour from all brown to green or scurfy with patches of green and brown. The figs are distinctively ridged . This tree is evidently a male from the rotting figs and evidence of the activity of black ants including black “ant sawdust” surrounding the figs and and a black sawdust covered ant trail leading from the bunch of figs to the ant’s nest at in the ground. The ants feed on the fig wasps which breed in male figs before the male fig wasps fly off to pollinate the female figs on a female F. francisci tree.
The leaves are slightly dentate or serrated round the edges and covered in silky hairs
Ficus francisci grows in the same wet forest habitat as a closely related fig, Ficus cereicarpa. See this link below on how to tell them apart;
