Paubrasilia

Paubrasilia echinata is a species of flowering plant in the legume family, Fabaceae. It is a Brazilian timber tree commonly known as Pernambuco wood or Brazilwood (Portuguese: pau-de-pernambuco, pau-brasil; Tupi Ibirapitanga). 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.
