Barringtonia asiatica, also known as fish poison tree, putat or sea poison tree, 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][6] This 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.

[7][8] It was transferred to the genus Barringtonia by the German botanist Wilhelm Sulpiz Kurz in 1875.

[2][3] The genus name was created to honour the English lawyer, antiquary and naturalist, Daines Barrington,[10] while the species epithet asiatica refers to the region where this species is found.

[11] The fruit is dispersed in the same way as a coconut – by ocean current – and is extremely water-resistant and buoyant.
