Introduction to Ficus (fig trees)

(Life; Embryophyta (plants); Angiospermae (flowering plants); Eudicotyledons; Order: Rosales; Family: Moraceae; Genus: Ficus)

There are about 755 fig tree species worldwide, with around 511 of them occurring in the Indo-Australasian region (Asia, Malesia, Pacific islands and Australia) and approximately 132 in the Neotropical region (Central and South America). In the Afrotropical region (Africa south of the sahara, including Madagascar) there are currently 112 recognised species, 36 of which are indigenous to southern Africa (25 species in South Africa).

We envisage that Figweb will become a comprehensive resource for information on the world's fig tree species and their associated fig wasps. The content of the fig pages has been largely drawn from Kees Berg's revisions of Afrotropical Ficus species - numerous publications (see references) culminating in the regional treatment on African fig trees and fig wasps (Berg & Wiebes 1992). Kees Berg (Norwegian Arboretum, University of  Bergen) has recently prepared a treatise of the Malesian Ficus for the Flora Malesiana and is currently preparing a treatise of the Neotropical Ficus species for the Flora Neotropica. Both Kees Berg and Stefan Ungricht (CBGP-INRA) have been instrumental in assisting with the compilation of the Indo-Australasian and Neotropical checklists.

Figweb provides an online resource that can be used as a virtual field guide to the figs of a specific geographical region, facilitating the identification of fig species in the field and promoting the collection of the associated fig wasp fauna from correctly identified host fig species.

Access to the fig species pages can either be via the alphabetical index, hierarchical classification or via the checklists for specific regions and countries. At the moment species coverage is largely limited to the Afrotropical region, but page development for the rest of the world's fig species is in progress. Ultimately, we aim to have complete coverage of all Ficus species.
