Nagalingam Tree


Nagalinga Tree

(Prosperity Tree and Flower)


I love most plants, herbs and trees.  Here is my compilation of information on one of those wonderful trees called Nagalingam.

Couroupita guianensis, whose common names include Ayahuma and the Cannonball Tree. 
It is a highly medicinal plant. Each and every part of this plant is used in all types of systems of medicine. C. guianensis is mentioned under threatened plants category in IUCN Red Data Book, because the habitat of this species has declined widely.

Couroupita guianensis, known by several common names, includingcannonball tree, is a deciduous treein the family LecythidaceaeIt is native to the rainforests of Central and South America. In India it has been growing for the past three thousand years at least, as attested by textual records, hence it is possible that it is native to India also.  Couroupita guianensis grows up to 35 m (meters) in height. The clustered leaves vary in length, generally from 8 to 31 centimeters, but reaching up to 57.  The flowers are born in large bunches up to 80 m(meters) long. Some trees flower profusely, until the entire trunk is buried in flowers. One tree can bear 1000 flowers per day. They are strongly scented, especially at night, and in the early morning.  They are large, up to 6 centimeters wide, and often brightly colored, the six petals in shades of pink and red near the bases and yellowish toward the tips. There is a ring of stamens at the center, and an arrangement to stamens that have been modified into a hood.  The large fruit, which is woody and very spherical, measuring up to 25 centimeters wide, gives the species the common name "cannonball tree". A smaller fruit contains perhaps 65 seeds, while a large one can have 550.  One tree can bear 150 fruits. The fruit takes up to a year to mature in most areas, sometimes as long as 18 months.

The trees are grown extensively in Shiva temples in India. In Hindi it is called Shiv Kamal and also known as "Kailaspati". It is called the Nagalingam tree in Tamil and Nagkeshar  in Bengali. The flowers are called Shivalinga flowers in Hindi; Nagalinga Pushpa in Kannada; Nagalingam in Malayalam; Nagamalli flowers or Mallikarjunaflowers in Telugu. Hindus revere it as a sacred tree because the petals of the flower resemble the hood of the Naga, a sacred snake, protecting a Shiva Lingam, the stigma. 
Pollination
The flowers lack nectar, but are very attractive to bees coming for the pollen. The carpenter bee Xylocopa brasilianorum is a common pollinator of cultivated trees in Rio de Janeiro, just outside the tree's native range. Other carpenter bees such as Xylocopa frontalis, as well as waspsflower flies, andbumblebees visit the flowers. The flowers produce two types of pollen, fertile pollen from the ring stamens and sterile pollen from the hood structure.
Dispersal
The fruit falls from the tree and often cracks open when it hits the ground. Sometimes they remain whole until an animal such as a peccary breaks it open. Many animals feed on the fruit pulp and the seeds, such as the pacaand domestic chickens and pigs. The seeds are coated with trichomes which may help them pass through animal intestines.
Human Uses
This tree is planted as an ornamental for its showy, scented flowers, and as a botanical specimen for its interesting fruit.
The fruit is fed to livestock such as pigs and domestic fowl.
The fruit is edible, but not usually eaten by people because it can have an unpleasant smell.
In India the tree is sacred to Hindus, who believe its hooded flowers look like the nāga, and it is grown at Shiva temples.
There are many medicinal uses for the plant. Native Amazonians use extracts of several parts of the tree to treat hypertension, tumors, pain, andinflammation. It has been used to treat the common cold, stomachache, skin conditions and wounds, malaria, and toothache.  The bark is used to treat hypertension, tumours, pain and inflammatory process.   Laboratory tests show that extracts of the plant have some antimicrobial activity and inhibit the formation of biofilms.  The fruit has an unpleasant odor and hence can be used as an infect-repellant by rubbing it to the skin or clothese.
The fruit pulp is rubbed on sick dogs to cure them of mange
Other uses:
1) Hard shells of the fruit sometimes used as containers and utensils. (2) Wood used for making furniture and also incense.  However, one blogger has stated that the wood is of substandard quality and there is little or no heartwood, it is unfit to be utilized in any useful activities.

The Puducherry Government has announced cannon ball flower (Nagalingam flower) as the State Flower.  It is the bound duty of Pondicherrians to propagate and conserve this plant in and around Puducherry.

The tree is also rich in providing anthocyanin, flavanoids, volatile constituents like eugenol and farsenol. The stem extracts of this plant is known to contain flavonoids, tannins, steroids, saponins, glycosides, amino acids, phenols, anthraquinones and triterpenoids.

The natural propagation of this plant is very slow and seeds directly shown in the soil could not germinate.  Work related to cloning, tissue culture and micropropagation from mature tissues is largely deficit in literature. Muniswamy and Sreenath (2000) germinated C. guianensis seed embryo in vitro because seeds directly shown in the soil could not germinate. They were successful in in vitro germination of seeds and development of plantlets.  There is urgent need to develop a plant regeneration protocol to conserve this threatened, religiously, socio-economically and ethno-botanically important plant species using biotechnological interventions.    

My experience:  I am student of Hindu High School, Triplicane, Chennai.  This tree was at the back of the school.  As a child, I was fascinated by the gigantic tree, its huge fruits and awesome flowers.  After my school days, I have hardly sighted this tree.  Though most of the blogs and writings on the tree say that the tree is venerated and the flowers are used in the puja of Lord Siva, I have not seen OR do not remember to have seen the tree in any one of the many Siva sthalams I had visited.  But, recently when I visited the Agastheeswarar Temple, Villivakkam, Chennai 600049, I was pleasantly surprised to see the tree.  I collected a few of the flowers which were on the ground and used them during the next day`s puja.  This latest sighting of the tree spurred me into looking for info in the internet and the result is this blog.

I am told that Lalbagh, Cubbon Park and Infantry Road, Bangalore have quite good number of trees.  Though, I was at these places a few times, I don`t remember to have seen them. 

Those who are interested in planting this tree can order at:

Jaiguru Nursery Garden +91-9865087523
Address: No. 1594, Nehru Nagar, Near hotel Adayar Anandha Bhavan, Polur Main Road, Vengikkal,, Tiruvannamalai -606604, Tamil Nadu, India

The Nagalinga flowers attract bees and they spring directly from the bark of the tree.
The fruits are woody and are of considerable weight and would do great harm to a person
If they were to fall on him.  Look at the photos below (with warning sign boards).

The information and photos are a collection from the internet at various times.  I heartily thank all those from whose posts they have been collected.  Some of the sources are mentioned below.
