Ficus is a genus of about 800 species of woody trees, shrubs and vines in the family Moraceae, native throughout the tropics with a few species extending into the warm temperate zone. The most well known species in the genus is the Common Fig.

Leaves of the Sacred Fig Ficus religiosa

One species of this genus, the Common Fig (F. carica), produces a commercial fruit called a fig; the fruit of many other species are edible though not widely consumed. Other examples of figs include the banyans and the Sacred Fig (Peepul or Bo) tree. Most species are evergreen, while some from temperate areas, and areas with a long dry season, are deciduous.

Fruit and pollination

The fig is commonly thought of as fruit, but it is properly the flower of the fig tree. It is in fact a false fruit or multiple fruit, in which the flowers and seeds grow together to form a single mass.

Common Fig fruit

The genus Dorstenia, also in the fig family (Moraceae), exhibits similar tiny flowers arranged on a receptacle but in this case the receptacle is a more or less flat, open surface.

A fig "fruit" is derived from a specially adapted type of inflorescence (structural arrangement of flowers). What is commonly called the "fruit" of a fig is actually a specialized structure- or accessory fruit- called a syconium: an involuted (nearly closed) receptacle with many small flowers arranged on the inner surface. Thus the actual flowers of the fig are unseen unless the fig is cut open. In Chinese the fig is called 'fruit without flower'. The syconium often has a bulbous shape with a small opening (the ostiole) at the distal end that allows access by pollinators. The flowers are pollinated by very small wasps that crawl through the opening in search of a suitable place to reproduce (lay eggs). Without this pollinator service fig trees cannot reproduce by seed. In turn, the flowers provide a safe haven and nourishment for the next generation of wasps. Technically, a fig fruit would be one of many mature, seed-bearing flowers found inside one fig.

Most figs come in two sexes: hermaphrodite (called caprifigs from goats - Caprinae subfamily; as in fit for eating by goats; sometimes called "inedible") and female (the male flower parts fail to develop; produces the "edible" fig). Fig wasps grow in caprifigs but not in the other because the female trees' female flower part is too long for the wasp to successfully lay her eggs in them. Nonetheless, the wasp pollinates the flower with pollen from the fig it grew up in, so figs with developed seeds also contain dead fig wasps almost too tiny to see.

When a caprifig ripens, another caprifig must be ready to be pollinated. Tropical figs bear continuouslyTemplate:Fact, enabling fruit-eating animals to survive the time between mast years. In temperate climes, wasps hibernate in figs, and there are distinct crops. Caprifigs have three crops per year; edible figs have two. The first of the two is small and is called breba; the breba figs are olynths. Some selections of edible figs do not require pollination at all, and will produce a crop of figs (albeit without fertile seeds) in the absence of caprifigs or fig wasps.

There is typically only one species of wasp capable of fertilizing the flowers of each species of fig, and therefore plantings of fig species outside of their native range results in effectively sterile individuals. For example, in Hawaii, some 60 species of figs have been introduced, but only four of the wasps that fertilize them have been introduced, so only four species of figs produce viable seeds there.

Propagation

Figs are also easily propagated from cuttings. An extraordinarily large self-rooted Wild Willowleaf Fig in South Africa is protected by the Wonderboom Nature Reserve.

Historical significance

In June 2006, it was reported that figs dating back 11,400 years were discovered at Gilgal I, a village in the Lower Jordan Valley, just 8 miles north of ancient Jericho.Template:Fact There is evidence that figs were among the first cultivated crop, because they were of a mutation which could not reproduce normally. It is proposed that they may have been planted and cultivated intentionally, one thousand years before the next crops were domesticated (wheat and rye).

The phallic shape of the young fig is referred to in Song of Songs chapter 2 verse 13. The fig tree is sacred to Dionysus Sukites (Συκίτης).

Figs were also a common foodsource for the Romans. Cato the Elder, in his De Agri Cultura, lists several strains of figs grown at the time he wrote his handbook: the Mariscan, African, Herculanean, Saguntine, and the black Tellanian (De agri cultura, ch. 8).

Figs and health

Dried figs

Figs are good source of flavonoids and polyphenols. Figs and other dried fruit were measured for their antioxidant content. A 40 gram portion of dried figs (two medium size figs) produced significant increase in plasma antioxidant capacity . Figs also have higher quantities of fiber than any other dried or fresh fruit.
