Caesalpinia echinata is a species of Brazilian timber tree in the pea family, Fabaceae. Common names include Brazilwood, Pau-Brasil, Pau de Pernambuco, Nicaragua wood and Ibirapitanga (Tupi). 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.
