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.
Sourwood or sorrel tree, Oxydendrum arboreum, is the sole species in the genus Oxydendrum, in the family Ericaceae.
 It is native to eastern North America, from southern Pennsylvania south to northwest Florida and west to southern Illinois; it is most common in the lower chain of the Appalachian Mountains.
 The tree is frequently seen as a component of oak-heath forests.
Ficus obliqua, commonly known as the small-leaved fig, is a tree in the family Moraceae, native to eastern Australia, New Guinea, eastern Indonesia to Sulawesi and islands in the southwestern Pacific Ocean.
 Previously known for many years as Ficus eugenioides, it is a banyan of the genus "Ficus", which contains around 750 species worldwide in warm climates, including the edible fig ("Ficus carica").
 Beginning life as a seedling, which grows on other plants (epiphyte) or on rocks (lithophyte), "F. obliqua" can grow to 60 m high and nearly as wide with a pale grey buttressed trunk, and glossy green leaves.
Ficus retusa is a species of evergreen woody plant in the fig genus, native to the Malay Archipelago and Malesia floristic region.
 The species name has been widely mis-applied to "Ficus microcarpa".
Ficus atricha, commonly known as the rock breaker fig, is a tree in the family Moraceae native to northwestern Australia.
 It is a banyan of the genus "Ficus" which contains around 750 species worldwide in warm climates, including the edible fig ("Ficus carica").
Ficus citrifolia, also known as the shortleaf fig, giant bearded fig or wild banyantree, is a species of banyan native to southern Florida, the Caribbean, Central America, and northern South America south to Paraguay.
 It is distinguished from the closely related Florida strangler fig ("Ficus aurea") mainly by the finer veining in the leaves.
Ficus maxima is a fig tree which is native to Mexico, Central America, the Caribbean and South America south to Paraguay.
 Figs belong to the family Moraceae.
 The specific epithet "maxima" was coined by Scottish botanist Philip Miller in 1768; Miller's name was applied to this species in the "Flora of Jamaica", but it was later determined that Miller's description was actually of the species now known as "Ficus aurea".
 To avoid confusion, Cornelis Berg proposed that the name should be conserved for this species.
 Berg's proposal was accepted in 2005.
Ficus benjamina, commonly known as weeping fig, benjamin fig or Ficus tree, and often sold in stores as just ficus, is a species of flowering plant in the family Moraceae, native to Asia and Australia.
 It is the official tree of Bangkok.
 The species is also naturalized in the West Indies and in the States of Florida and Arizona in the United States.
Ficus subpisocarpa (called 笔管榕 in China and 雀榕 in Taiwan) is a species of small deciduous tree native to Japan, China, Taiwan and southeast Asia to the Moluccas (Ceram).
 Two subspecies are recognised.
 Terrestrial or hemiepiphytic, it reaches a height of 7 m (23 ft).
 Ants predominantly of the genus "Crematogaster" have been recorded living in stem cavities.
 "Ficus subpisocarpa" is pollinated by "Platyscapa ishiiana" (Agaonidae).
Ficus brachypoda is a tree in the family Moraceae native to northern Australia.
 It is a banyan of the genus "Ficus" which contains around 750 species worldwide in warm climates, including the edible fig ("Ficus carica").
