Paubrasilia echinata is a species of flowering plant in the legume family, Fabaceae, and is endemic to the Atlantic Forest. It is a Brazilian timber tree commonly known as Pernambuco wood or brazilwood (Portuguese: pau-de-pernambuco, pau-brasil; Tupi: Ibirapitanga) and is the national tree of Brazil. This plant has a dense, orange-red heartwood that takes a high shine, and it is the premier wood used for making bows for stringed instruments. The wood also yields a red dye called brazilin, which oxidizes to brazilein.
