Erythrina fusca is a species of flowering tree in the legume family, Fabaceae.

It is known by many common names, including purple coraltree, gallito, bois immortelle, bucayo, and the more ambiguous "bucare" and "coral bean".

It grows on coasts and along rivers in tropical Asia, Oceania, the Mascarene Islands, Madagascar, Africa, and the Neotropics.

[2] The easy-to-grow and attractive flowering tree is cultivated as an ornamental shade and hedge plant.

[4] Like many other species in the genus Erythrina, E. fusca contains toxic alkaloids which have been utilized for medicinal value but are poisonous in larger amounts.
