Ficus

Ficus is a genus of about 850 species of woody trees, shrubs, vines, epiphytes, and hemi epiphytes 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 so-called Common Fig (F. carica) is a temperate species from the Middle East and eastern Europe (mostly Ukraine), which has been widely cultivated from ancient times for its fruit, also referred to as figs.Figs occupy a wide variety of ecological niches. Take, for example, the Common Fig, a small temperate deciduous tree whose fingered fig leaf is well-known in art and iconography; or the Weeping Fig (F. benjamina) a hemi-epiphyte with thin tough leaves on pendulous stalks adapted to its rain forest habitat; or the rough-leaved sandpaper figs from Australia; or the Creeping Fig (F. pumila), a vine whose small, hard leaves form a dense carpet of foliage over rocks or garden walls. Moreover, figs with different plant habits have undergone adaptive radiation in different biogeographic regions, often leading to very high levels of alpha diversity. In the tropics, it is quite common to find that Ficus is the most species-rich plant genus in a particular forest. In Asia as many as 70 or more species can co-exist.

A fig "fruit" is derived from a specially adapted type of inflorescence (an arrangement of multiple flowers). In this case, it is 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 Bengali, where the Common Fig is called dumur, it is referenced in a proverb: tumi jeno dumurer phool hoe gele ("You have become [invisible like] the dumur flower").

The syconium often has a bulbous shape with a small opening (the ostiole) at the outward end that allows access to pollinators. The flowers are pollinated by very small wasps that crawl through the opening in search of a suitable place to 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. This accounts for the frequent presence of wasp larvae in the fruit. Technically, a fig fruit proper would be one of the many tiny mature, seed-bearing flowers found inside one fig - if you cut open a fresh fig, the flowers will appear as fleshy "threads", each bearing a single seed inside.

The fig plants can be monoecious (hermaphrodite) or dioecious (hermaphrodite and female).
