Pretty red flowers on a small tree, the flowers upturned or curved like crescents. Called coral trees or coral bean, the genus is Erythrina in the pea family, Fabaceae, and they are found all around the tropical world.
My most recent encounter with a coral tree was with Erythrina crista-galli, the cockspur coral tree (crista-galli is Latin for cock's comb) in Argentina, where, called ceibo, it is the national flower. Cockspur coral tree is native to northern Argentina and nearby areas in Paraguay, Uruguay and southern Brazil. It is the national flower of Uruguay, as well.
Which tells you how spectacular the cockspur coral tree is in flower.
