Alexandrian Laurel scientifically known as Calophyllum inophyllum is a low-branching evergreen tree belongings to Clusiaceae ⁄ Guttiferae (Mangosteen family) with a broad, spreading crown of irregular, gnarled branches. The plant is native to Old world tropics from East Africa, southern coastal India to Malesia, northern Australia and the Pacific islands. It is primarily a tree of the seashore and adjacent lowland forests, though it occasionally grows at higher elevations and has been effectively planted in inland areas. Other common names occasionally used include Alexandrian Laurel, Ball Nut, Ball Nut Tree, Beach Callophyllum, Beauty Leaf, Borneo Mahogany, Indian Laurel, India-Oil Nut, Laurelwood, Mastwood, Oi Nut Tree, Portia Tree, Poon, Poonay Oil Plant, Satin Touraga, Sweet-Scented Calophyllum, Indian doomba oiltree, Ball tree, Beach touriga, Satin touriga, Tacamahac-tree, kamani tree, Palomaria, Takamaka, Indian doomba oiltree, mastwood beauty-leaf, dingkaran, dilo oil tree and indiapoon beauty leaf.

The Alexandrian Laurel has derived its generic name from the Greek terms ‘kalos’ denoting beautiful and ‘phullon’ meaning leaf. In other words, the generic name of this species means the beautiful-leafed tree in Greek. Similarly, the precise nickname (epithet) of this tree also has its origin in two Greek words – ‘is’ meaning fiber and ‘phullon’ denoting leaf that refers to the prominent veins on the underside of the leaves of the Alexandrian Laurel.

The tree is cultivated for providing shade as well as reforestation and afforestation – an initiative to reclaim soil. In many places, tree is also planted along the shores because it has proved to be effective in preventing soil erosion by the sea. While the growth of the tree is very sluggish, it is very popular as a roadside plantation in India. Additionally, it is also an attractive ornamental plant, as it has young foliage that is crimson in color. Even the flowers are very aromatic.

The plant is found growing naturally on rocky and sandy sea shores, just above the high tide mark, in plains along the banks of rivers and mangrove forests, also planted in the parks and roadsides. The plant occurs on a wide range of soils including clays, loams, calcareous, rocky and gravelly soils but performs best on well-drained, sandy soils. It is also tolerant of saline soils.

History

Alexandrian Laurel is a native of the old world tropics from East Africa, southern coastal India to Malesia, northern Australia and the Pacific islands. The species is extensive along the coasts of eastern Africa (from Kenya to northern Mozambique), Madagascar and other Indian Ocean islands, tropical Asia, northern Australia and the islands of the Pacific Ocean. Although it is considered wild in most of this area, it is often unclear where it is truly wild or a relict of former cultivation. In Reunion and Mauritius it has possibly been introduced. In Africa, it is locally planted outside the natural distribution area, e.g. in Guinea, Sierra Leone, Côte d’Ivoire, Ghana, Nigeria, Cameroon and Gabon, where outwardly wild trees and seedlings can be found near beaches. The species is also planted in southern China.
