"Banyan" often refers specifically to the species "Ficus benghalensis", though the term has been generalized to include all figs that share a unique life cycle, and systematically to refer to the subgenus "Urostigma". [Note usage of "Banyan" versus "banyan" in PDF| [http://www.ias.ac.in/resonance/July1997/pdf/July1997NatureWatch.pdf "Trees with a Difference: The Strangler Figs"] |61.0 KiB by Vidya R Athreya, "Nature Watch", July 1997; also [http://depts.washington.edu/tc596jan/samoa/playground/banyans.php?r=n "Aerial-rooting banyan trees"] , washington.edu] The seeds of banyans are dispersed by fruit-eating birds. The seeds germinate and send down roots towards the ground, and may envelope part of the host tree or building structure with their roots, giving them the casual name of "strangler fig". The "strangling" growth habit is found in a number of tropical forest species, particularly of the genus "Ficus", that compete for light. [Zhekun, Zhou & Michael G. Gilbert (2003) Flora of China (Moraceae) 5: 21-73. [http://hua.huh.harvard.edu/china/mss/volume05/Moraceae.pdf] ] [Serventy, V. 1984. Australian Native Plants. Victoria: Reed Books.] [Light in the rainforest 1992 Tropical topics. Vol 1 No. 5 [http://www.epa.qld.gov.au/register/p00820ar.pdf] ] Any "Ficus" species showing this habit may be termed a strangler fig.

Older banyan trees are characterized by their aerial prop roots which grow into thick woody trunks which, with age, can become indistinguishable from the main trunk. Old trees can spread out laterally using these prop roots to cover a wide area. The largest such tree is now found in Kolkata in India. One of the most famous of banyan trees was planted in Kabirvad, Gujarat. Records show that Kabirvad is more than 300 years old. Another famous banyan tree was planted in 1873 in Lahaina's Courthouse Square in Hawai'i, and has now grown to cover two-thirds of an acre.

Like other Fig species (which includes the common edible fig "Ficus carica"), banyans have unique fruit structures and are dependent on fig wasps for reproduction. Banyan, Ficus benghalensis or the Indian Fig Tree is the National tree of India.cite web| url=http://india.gov.in/knowindia/national_tree.php| title=National Tree| publisher= Government of India| accessdate=2009-04-29]

Etymology

The name was originally given to "F. benghalensis" and comes from India where early travellers observed that the shade of the tree was frequented by "banias" or Indian traders. [Yule, Henry, Sir. Hobson-Jobson: A glossary of colloquial Anglo-Indian words and phrases, and of kindred terms, etymological, historical, geographical and discursive. New ed. edited by William Crooke, B.A. London: J. Murray, 1903.]

In the Gujarati language, banyan means "merchant", not "tree". The Portuguese picked up the word to refer specifically to Hindu merchants and passed it along to the English as early as 1599 with the same meaning. By 1634, English writers began to tell of the banyan tree, a tree under which Hindu merchants would conduct their business. The tree provided a shaded place for a village meeting or for merchants to sell their goods. Eventually banyan came to mean the tree itself.

Classification

The proper noun Banyan refers specifically to the species "F. benghalensis", which can grow into a giant tree covering several hectares. Over time, the name became generalized to all strangler figs. It appears that "banyan" is the more common term in Asia, Australia and Oceania, while "strangler fig" is more often used in the Americas and Africa.Fact|date=May 2007 There are many banyan species, including:
*"Ficus microcarpa", which is native from Sri Lanka through New Caledonia and is a significant invasive species elsewhere.
*The Central American Banyan ("Ficus pertusa") is native to Central America and northern South America, from southern Mexico south to Paraguay.
*The Shortleaf Fig ("Ficus citrifolia") is native to southern Florida, the Caribbean Islands, Central America and South America south to Paraguay. One theory is that the Portuguese name for "F. citrofolia", "Os Barbados", gave Barbados its name
*The Florida Strangler Fig ("Ficus aurea") is also native to southern Florida and the Caribbean Islands, and distinguished from the above by its coarser leaf venation.
*The Moreton Bay Fig ("Ficus macrophylla") and Port Jackson Fig ("Ficus rubiginosa") are other related species.

Ornamental Value

Due to the complex structure of the roots and extensive branching, the banyan is extensively used for creating Bonsai. Taiwan's oldest living bonsai is a 240-year-old banyan housed in Tainan.

In culture

;Religion and mythology
* In Hinduism, the banyan tree is considered sacred and is called "Ashwath Vriksha." God Siva as Dakshinamurthy is nearly always depicted sitting in silence under the banyan with rishis at His feet. It is thought of as perfectly symbolizing eternal life due to its seemingly unending expansion.
* Also in Hindu culture, the banyan tree is also called kalpavriksha meaning 'wish fulfilling divine tree'. In modern parlance in the Hindi language, it is known as Bargad, Vatavriksh, and Barh.
