Banyan

A banyan, also spelled "banian" (/ˈbænjən/ BAN-yən),[1] is a fig that develops accessory trunks from adventitious prop roots, allowing the tree to spread outwards indefinitely.[2] This distinguishes banyans from other trees with a strangler habit that begin life as an epiphyte,[3] i.e. a plant that grows on another plant, when its seed germinates in a crack or crevice of a host tree or edifice. "Banyan" often specifically denotes Ficus benghalensis (the "Indian banyan"), which is the national tree of India,[4] though the name has also been generalized to denominate all figs that share a common life cycle and used systematically in taxonomy to denominate the subgenus Urostigma.[5]

This article is about the tree. For other uses, see Banyan (disambiguation).

Characteristics
Ancient banyan tree
Ripe banyan fruits

Like other fig species, banyans bear their fruit in the form of a structure called a "syconium". The syconium of Ficus species supply shelter and food for fig wasps and the trees depend on the fig wasps for pollination.

Frugivore birds disperse the seeds of banyans. The seeds are small, and because most banyans grow in woodlands, a seedling that germinates on the ground is unlikely to survive. However, many seeds fall on the branches and stems of other trees or on human edifices, and when they germinate they grow roots down toward the ground and consequently may envelop part of the host tree or edifice. This is colloquially known as a "strangler" habit, which banyans share with a number of other tropical Ficus species, as well as some other unrelated genera such as Clusia and Metrosideros.[2][6][7][8]

The leaves of the banyan tree are large, leathery, glossy, green, and elliptical. Like most figs, the leaf bud is covered by two large scales. As the leaf develops the scales abscise. Young leaves have an attractive reddish tinge.[9]

Older banyan trees are characterized by aerial prop roots that mature into thick, woody trunks, which can become indistinguishable from the primary trunk with age. These aerial roots can become very numerous. the Kolcatta (Calcutta) Banyan, which has been tracked carefully for many years, currently has 2,880 supplementary trunks.[10] Such prop roots can be sixty feet (eighteen meters) in height.[11][12] Old trees can spread laterally by using these prop roots to grow over a wide area. In some species, the prop roots develop over a considerable area that resembles a grove of trees, with every trunk connected directly or indirectly to the primary trunk. The topology of this massive root system inspired the name of the hierarchical computer network operating system "Banyan VINES".

Looking upward inside a strangler fig where the host tree has rotted away, leaving a hollow, columnar fig tree

In a banyan that envelops its host tree, the mesh of roots growing around the latter eventually applies considerable pressure to and commonly kills it. Such an enveloped, dead tree eventually decomposes, so that the banyan becomes a "columnar tree" with a hollow, central core. In jungles, such hollows are very desirable shelters to many animals.

From research, it is known that the longevity of banyan tree is due to multiple signs of adaptive (MSA) evolution of genes.[13]

Etymology

The name was originally given to F. benghalensis and comes from India, where early European travelers observed that the shade of the tree was frequented by Banyans (a corruption of Baniyas, a community of Indian traders).[14]

Classification

The original banyan, F. benghalensis, can grow into a giant tree covering several hectares. Over time, the name became generalized to all strangler figs of the Urostigma subgenus. The many banyan species also include:

In horticulture

Due to the complex structure of the roots and extensive branching, the banyan is used as a subject specimen in penjing and bonsai. The oldest living bonsai in Taiwan is a 240-year-old banyan tree housed in Tainan.[16]

In culture

Religion and mythology

Banyan trees figure prominently in several Asian and Pacific religions and myths, including:

  • In Hinduism, the leaf of the banyan tree is said to be the resting place for the god Krishna.
In the Bhagavat Gita, Krishna said, "There is a banyan tree which has its roots upward and its branches down, and the Vedic hymns are its leaves. One who knows this tree is the knower of the Vedas." (Bg 15.1) Here the material world is described as a tree whose roots are upwards and branches are below. We have experience of a tree whose roots are upward: if one stands on the bank of a river or any reservoir of water, he can see that the trees reflected in the water are upside down. The branches go downward and the roots upward. Similarly, this material world is a reflection of the spiritual world. The material world is but a shadow of reality. In the shadow there is no reality or substantiality, but from the shadow we can understand that there is substance and reality.
Vat Purnima is a Hindu festival related to the banyan tree. Vat Purnima is observed by married women in North India and in the Western Indian states of Maharashtra, Goa, Gujarat.[17] During the three days of the month of Jyeshtha in the Hindu calendar (which falls in May–June in the Gregorian calendar) married women observe a fast and tie threads around a banyan tree and pray for the well-being of their husbands.[18]
  • In Buddhism's Pali canon, the banyan (Pali: nigrodha)[19] is referenced numerous times.[20] Typical metaphors allude to the banyan's epiphytic nature, likening the banyan's supplanting of a host tree as comparable to the way sensual desire (kāma) overcomes humans.[21]
  • In Guam, the Chamorro people believe in tales of taotaomona, duendes, and other spirits. Taotaomona are spirits of the ancient Chamorro that act as guardians to banyan trees.[22]
  • In Vietnamese mythology of the Mid-Autumn Festival, the dark markings on the Moon are a banyan, a magical tree originally planted by a man named Cuội on Earth. When his wife watered it with unclean water, the tree uprooted itself with the man hanging on it and flew to the Moon, where he eternally accompanied the Moon Lady and the Jade Rabbit.[23][24]
  • In the Philippines, they are usually referred to as balete trees, which are home to certain deities and spirits.[25]
  • In Okinawa, the tree is referred to as gajumaru, which, according to traditional folklore, is the home for the mythical Kijimuna.
