Sarpagandhi
Curopita gianensis, also known as cannon tree, Nagalingam, and Sarpagandhi, is a deciduous tree in the flowering plant family Lecithidaceae that belongs to the genus Curopita. It is native to the tropical forests of Central and South America and is cultivated in tropical regions around the world for its beautiful, fragrant flowers and large, juicy fruits. The fruits are brownish grey. Curopita gianensis has medicinal properties in several parts, and the tree has cultural and religious significance in India. According to legend, the British brought the tree to Sri Lanka in 1881, but it was widely misidentified as Sal, and it is now commonly grown as a tree in Buddhist temples. The French botanist Jean-Baptiste Christopher Fussy Aublet named the tree Curopita gianensis in 1775.
The Latin specific
epithet gianensis means "of the Guianas" (a region in north-eastern
South America). Its botanical name is Curopita gianensis, and it is also known
as Nagalinga or Top Gola in Hindi, Lingada Mara or Nagalingam in Kannada,
Shivalingam in Marathi, Kaman Gola in Bengali, and Nagalingam in Tamil. Hindus
revere the cannon tree in India. Curopita gianensis is a 35-meter-tall tree.
Leaves clustered at the tips of branches are typically 8 to 31 cm long, but can
reach up to 57 cm in length, and flowers are borne in racemes up to 80 cm long.
Some trees have racemes that cover the entire branch and bloom profusely. This
tree is also notable for its ability to produce up to 1000 flowers per day. The
flowers are particularly fragrant at night and in the early morning.
These flowers can
grow up to 6 cm in diameter. It has six petals and is usually brightly
coloured, but the petals at the base can be seen in shades of pink, red, and
yellow. Its fruits have a woody outer skin and are spherical in shape with a
diameter of up to 25 cm, giving rise to the tree's vernacular nickname of
cannon tree due to their resemblance to the cannon tree. Small fruits can have
up to 65 seeds, while larger ones can have up to 550 seeds. Each season, one tree
can produce up to 150 fruits. The fruit takes up to a year to ripen in most
areas, but it can take up to 18 months in some. Although the fruit's flesh is
white, when cracked open, it turns blue due to air reaction and oxidation.
Although the flowers do not contain honey, they are very appealing to bees that
come for pollen.
Seeds are spread by
animals that consume the fruits. When the fruit falls to the ground, the hard
woody shell cracks, releasing the pulp and seeds. Animals such as peccaries can
break intact fruits. Many animals, including peccaries, domestic chickens, and
pigs, consume the pulp and seeds. Trichomes cover the seeds. The Curopita
gianensis fruit is edible, but it is rarely consumed by humans because, unlike
its intensely fragrant flowers, its fruits have an unpleasant odor that humans
cannot tolerate. However, in some places, it is fed to livestock such as pigs
and domestic chickens. Similarly, parts of this plant are used in traditional
medicine in some Amazonian communities. Although there is little information on
its effectiveness, it is used to treat high blood pressure, tumors, pain,
inflammation, colds, abdominal pain, skin diseases, wounds, malaria, and
toothache. As a result, no one should use it to treat diseases. This tree is sacred
to Hindus in India, and you can find it near most temples.
Let me reveal a
little secret to you. Its flowers are regarded as a symbol of wealth and
prosperity throughout Asia. It is mostly grown in Shiva temples because its
veiled flowers resemble Nagas, and a Shivalinga-shaped part can be seen in the
centre of the flower. In Asia, the tree is frequently planted in Buddhist and
Hindu centres in the belief that it is a tree of sacred scriptures. It is also
found in Buddhist monasteries and other religious sites throughout Sri Lanka,
Thailand, and other Buddhist countries. Its pulp is used as fodder for domestic
pigs and chickens in the region.
