Ficus
Summary
Ficus (ˈfaɪkəs or ˈfiːkəs) is a genus of about 850 species of woody trees, shrubs, vines, epiphytes and hemiepiphytes in the family Moraceae. Collectively known as fig trees or figs, they are native throughout the tropics with a few species extending into the semi-warm temperate zone. The common fig (F. carica) is a temperate species native to southwest Asia and the Mediterranean region (from Afghanistan to Portugal), which has been widely cultivated from ancient times for its fruit, also referred to as figs. The fruit of most other species are also edible though they are usually of only local economic importance or eaten as bushfood. However, they are extremely important food resources for wildlife. Figs are also of considerable cultural importance throughout the tropics, both as objects of worship and for their many practical uses.
Ficus is a pantropical genus of trees, shrubs, and vines occupying a wide variety of ecological niches; most are evergreen, but some deciduous species are found in areas outside of the tropics and to higher elevations. Fig species are characterized by their unique inflorescence and distinctive pollination syndrome, which uses wasp species belonging to the family Agaonidae for pollination.
Specific identification of many of the species can be difficult, but members of the genus Ficus are relatively easy to recognize. Many have aerial roots and a distinctive shape or habit, and their fruits distinguish them from other plants. The fruit of Ficus is an inflorescence enclosed in an urn-like structure called a syconium, which is lined on the inside with the fig's tiny flowers that develop into multiple ovaries on the inside surface. In essence, the fig fruit is a fleshy stem with multiple tiny flowers that fruit and coalesce.
The unique fig pollination system, involving tiny, highly specific wasps, known as fig wasps that enter via ostiole these subclosed inflorescences to both pollinate and lay their own eggs, has been a constant source of inspiration and wonder to biologists.
