Barringtonia asiatica (fish poison tree,[4][5] putat[4] or sea poison tree[4]) is a species of Barringtonia native to mangrove habitats from islands of the Indian Ocean in the west to tropical Asia and islands of the western Pacific Ocean.[4][5] It is grown along streets for decorative and shade purposes in some parts of India, for instance in some towns on the southeastern shore.[citation needed] It is also known as Box Fruit due to the distinct box-shaped fruit it produces.[6][failed verification] The local name futu is the source of the name for the Polynesian island Futuna.[7][failed verification]

Description
editIt is a small to medium-sized tree growing to 7–25 m tall. The leaves are narrow obovate, 20–40 cm in length and 10–20 cm in width. Fruit produced as mentioned earlier, is otherwise aptly known as the Box Fruit, due to distinct square like diagonals jutting out from the cross section of the fruit, given its semi spherical shape form from stem altering to a subpyramidal shape at its base. The fruit measures 9–11 cm in diameter, where a thick spongy fibrous layer covers the 4–5 cm diameter seed.[4][8]
Taxonomy
editThis species was first described in 1753 as Mammea asiatica by Carl Linnaeus, based on material collected from Java by Pehr Osbeck, a Swedish naturalist and one of Linnaeus' apostles.[9][10] It was transferred to the genus Barringtonia by the German botanist Wilhelm Sulpiz Kurz in 1875.[11] A number of other botanists have described various collected specimens under different names, which are all now recognised as synonyms (see synonyms list).[2][3]
Etymology
editThe genus name was created to honour the English lawyer, antiquary and naturalist, Daines Barrington,[12] while the species epithet asiatica refers to the region where this species is found.[13]
Ecology
editThe fruit is dispersed in the same way as a coconut – by ocean current – and is extremely water-resistant and buoyant.[14] It can survive afloat for up to fifteen years;[6][failed verification] it was one of the first plants to colonise Anak Krakatau when this island first appeared after the Krakatau eruption.[4] When washed ashore, and soaked by rainwater, the seeds germinate.
Human use
editAll parts of the tree are poisonous, the active poisons including saponins. Box fruits are potent enough to be used as a fish poison. The seeds are ground to a powder and used to stun or kill fish for easy capture,[4] suffocating the fish while the flesh is unaffected.[15]
