Ficus rosulata growing in the forest just behind the Ulu Ulu Resort, Temburong, Brunei. This fig is common in damp lowland primary forest throughout Borneo up to at least 900 m in the Crocker Range. The green cauliferous figs are dispersed by small Cynopterus fruit bats.Ficus rosulata is disitinguished from other green cauliferous figs by the pyramidal bracts that cover the ostiole (hole) at the base of the fig.The brown “soil ” surrounding these figs is believed to be the remnants of the gall flowers removed by ants from the male fig fruits after the fig wasps have emerged. It is believed that the ants do this so that the ants can use the empty male fig fruits as temporary domatia (homes). This hypothesis has yet to be fully investigated.
