Diagnostics:

Ficus fistulosa is a very common fig tree in secondary forests. It can be easily recognised by two characters. First, the shape of the leaves, being elongated and broader at the ends. Second, it is only one of the two native Ficus tree species that produce figs on their trunks and branches; the other being Ficus variegata (Ng et al., 2005). The young twigs are also hollow.


Interesting Facts:

The fig-wasps responsible for pollination of the Common Yellow Stem-Fig is Ceratosolen hewitti (Galil, 1973).
