Atlantic Forest in the context of "Minas Gerais"

Paubrasilia echinata is a species of flowering plant in the legume family, Fabaceae, that is endemic to the Atlantic Forest of Brazil. It is a Brazilian timber tree commonly known as brazilwood (pau-brasil; Tupi: ybyrapytanga) 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 historically important red dye called brazilin, which oxidizes to brazilein.

The name pau-brasil was applied to certain species of the genus Caesalpinia in the medieval period, and was given its original scientific name Caesalpinia echinata in 1785 by Jean-Baptiste Lamarck. More recent taxonomic studies have suggested that it merits recognition as a separate genus, and it was thus renamed Paubrasilia echinata in 2016. The Latin specific epithet of echinata refers to hedgehog, from echinus, and describes the thorns which cover all parts of the tree (including the fruits).

Engenho (Portuguese pronunciation: [ẽˈʒẽɲu]) is a colonial-era Portuguese term for a sugar cane mill and the associated facilities. In Spanish-speaking countries such as Cuba and Puerto Rico, they are called ingenios. Both words mean engine (from latin ingenium). The word engenho usually only referred to the mill, but it could also describe the area as a whole including land, a mill, the people who farmed and who had a knowledge of sugar production, and a crop of sugar cane. A large estate was required because of the massive amount of labor needed to yield refined sugar, molasses, or rum from raw sugar cane. These estates were prevalent in Brazil, Cuba, Dominican Republic, and other countries in the Caribbean. Today, Brazil is still one of the world's major producers of sugar. Sugarcane cultivation has resulted in deforestation and environmental devastation of Brazil's Atlantic Forest since the onset of colonization.

The Tupinambá (plural: Tupinambás) are one of the various Tupi ethnic groups that inhabit present-day Brazil, and who had been living there long before the conquest of the region by Portuguese colonial settlers. The name Tupinambá was also applied to other Tupi-speaking groups, such as the Tupiniquim, Potiguara, Tupinambá, Temiminó, Caeté, Tabajara, Tamoio, and Tupinaé, among others. Before and during their first contact with the Portuguese, the Tupinambás had been living along the entire Eastern Atlantic coast of Brazil.

In a sense, the name can be applied exclusively to the Tupinambás who once inhabited the right shore of the São Francisco River (in the Recôncavo Baiano, Bahia), and from the Cabo de São Tomé (in Rio de Janeiro) to the town of São Sebastião (in São Paulo). Their language survives today in the form of Nheengatu.
