Ficus ruginervia belongs to the same Section Kalosyce as Ficus punctata Borneo’s largest fig but is only half the size.
When ripe these figs vary from 2-5 cm in diameter which is too large for most hornbills to swallow so this fig has obviously evolved for primate and civet dispersal.

Female Section Kalosyce figs contain two type of flowers (1) Normal female flowers with stigma, style and ovary. After pollination by fig wasps the ovaries develop seeds ((2) Sterile red fleshy neuter flowers. It is obviously these fleshy red flowers which are the attraction for dispersers such as binturongs and gibbons to eat the fig. When eating the fig they unwittingly ingest the seeds which are later defecated.
