FICUS AMPELAS SECTION SYCIDIUM
According to Berg and Corner (2005) “The presence of this species in Borneo is not very certain, as it is represented by a single collection (by De Vriese) without precise indication of provenance.
If naturally dispersed this fig is most likely to be found on one of Borneo’s north or east coast islands.
The young leaves of this fig are frequently eaten as a vegetable by locals within the range – so there is a possibility that it could be introduced to Borneo.
