The Ficus barba-jovis liana is the patch of green leaves closely pressed against the trunk high up on a tall Dipterocarp Shorea pauciflora. The liana appears to originate from an Asplenium nidus (Birds Nest Fern) also growing on the same tree. This tree has been named locally as the Kabili Monster.
