Paubrasilia echinata is a flowering plant belonging to the Fabaceae family. This family is also known as the legume or pulse family. This specific tree is endemic to the Atlantic Forest of Brazil. It serves as the national tree of Brazil. The species is highly valued for its dense, orange-red heartwood. This wood takes a high shine when polished. It is also a source of a red dye called brazilin. Because of this tree, the country of Brazil received its name. The name is a shortened version of 'land of brazilwood.'

The physical structure of the tree is quite distinctive. It can reach a height of up to 15 meters. The dark brown bark often flakes off in large patches. This reveals a lustrous, blood-red sapwood underneath. The leaves are pinnate, meaning they are divided into smaller leaflets. Each leaf consists of between 9 and 19 small, leathery leaflets. These leaflets are generally a broad, oblong shape. The tree also features an inflorescence, which is a branched flower stalk. This stalk holds between 15 and 40 yellow flowers. These flowers are strongly perfumed and often have a blood-red blotch on the petals. Bees may act as pollinators for these flowers.

Every part of the tree carries a specific defense. The name 'echinata' comes from the Latin word for hedgehog. This refers to the small thorns that cover the branches, leaves, and fruit. The fruit itself is an oval-shaped woody seedpod. These pods can measure up to 10 centimeters long. Once the seeds are expelled, the remaining pods become twisted. Some researchers believe that different populations of the tree may belong to separate subspecies. Local people have also used the tree for medicinal purposes. It has been used as an astringent and an antidiuretic. Scientists have even tested extracts for possible cancer treatments.

The history of this tree is tied to global trade. In 1500, Portuguese explorers arrived on the South American coast. They found the wood was very abundant near rivers and coasts. They recognized it as a relative of sappanwood from Asia. Sappanwood was already used in Europe to make red dye for luxury textiles like velvet. The Portuguese called the tree 'pau-brasil,' meaning reddish or ember-like wood. This trade became a massive, profitable operation. It was managed as a crown-granted monopoly by the Portuguese. This wealth even led to conflicts with other nations. For example, a French expedition in 1555 tried to establish a colony in Rio de Janeiro. This attempt was motivated by the economic value of the brazilwood.

Scientific classification of the tree has changed over time. In 1785, Jean-Baptiste Lamarck gave it the name Caesalpinia echinata. Later, taxonomic studies suggested it deserved its own genus. In 2016, it was officially renamed Paubrasilia echinata. The wood is famous in the music industry for making stringed-instrument bows. It is considered superior to almost all other materials for this purpose. In this context, musicians often call it 'Pernambuco wood.' This name comes from the Brazilian state of Pernambuco.

However, the high demand for this wood caused serious problems. During the 18th century, excessive harvesting led to a steep decrease in tree numbers. This caused the entire wood trade to collapse. Today, the species is nearly extirpated in most of its original range. The IUCN lists the tree as an endangered species. It is also on the official list of endangered flora in Brazil. This shortage has helped the carbon fiber and composite bow industry grow.

Conservation efforts are now underway to save the species. The International Pernambuco Conservation Initiative (IPCI) is working to replant trees. These members are bowmakers who rely on the wood for their livelihoods. At the 2024 CITES meeting, leaders decided to register existing wood stockpiles. They also decided that finished bows should be marked to ensure they are traceable. Replanting in the wild is difficult because it is a climax community species. This means it grows best when planted among secondary forest vegetation. Some trees have been planted in urban areas like São Paulo. While they usually struggle, they did fruit abundantly there in 2009 due to a humid season.
