  Ficus is one of the largest plant genera of the tropics, which enjoys a cosmopolitan distribution. There are about 755 fig tree species worldwide, with around 511 of them occurring in the Indo-Australasian region (Asia, Malaysia, Pacific islands and Australia) and approximately 132 in the Neotropical region (Central and South America) (van Noort, Gardiner and Tolley, 2007).
