Paubrasilia

This special tree grows in Brazil.

It has many small thorns. These thorns cover the branches and the fruit. The tree has yellow flowers. The flowers smell very strong.

The wood inside is a bright red color. People use this wood to make bows for music.

Long ago, people used the wood to make red dye. This dye was used for fine cloth. This is why the land got its name.

Now, there are not many of these trees left. People are working to plant new ones. We must help this tree grow.

The brazilwood tree is a special plant from Brazil.

It is the national tree of Brazil. This tree has many small thorns. These thorns cover the branches and the fruit. The tree has yellow flowers with red spots. These flowers have a strong smell.

The wood inside is a bright orange-red color. People use this wood to make bows for stringed instruments. A bow is the stick used to play music.

Long ago, people used the wood to make red dye. This dye was used to color fine cloth. This trade was so big that the land became known as Brazil.

Today, these trees are in danger. People cut down too many of them in the past. Now, the species is listed as endangered. This means there are not many left in the wild. Some groups are working to plant new trees. They want to make sure the wood stays around for the future.

The brazilwood tree is a very special plant from Brazil.

It is known by its scientific name, Paubrasilia echinata. This tree is the national tree of Brazil. It belongs to the legume family, which is also called the pulse family. The name "echinata" comes from a Latin word meaning hedgehog. This name fits well because small thorns cover the branches, leaves, and fruit.

This tree has a very interesting way it works. It can grow up to 15 meters tall. The bark is dark brown and flakes off in large patches. Under the bark, the sapwood looks like bright red blood. The leaves are leathery and have between 9 and 19 small parts. The tree produces yellow flowers with red spots. These flowers have a strong smell that might attract bees.

The fruit is an oval seedpod that can be 10 centimeters long. After the seeds fall out, the woody pods become twisted.

People have studied this tree for a long time. In 1785, a scientist named Jean-Baptiste Lamarck gave it a scientific name. It was first called Caesalpinia echinata. Later, studies showed it should be its own group. In 2016, it was renamed Paubrasilia echinata. Long ago, Portuguese explorers saw these trees in 1500. They saw the wood was very common along the coast and rivers.

The wood is famous for two main things. First, it makes a great red dye called brazilin. When this dye meets air, it turns into brazilein. This was used to color expensive fabrics like velvet. Second, the orange-red heartwood is perfect for making bows for stringed instruments. Musicians often call this wood "Pernambuco wood" after the Brazilian state of Pernambuco.

Because the dye was so valuable, the land became known as Brazil. This name means "land of brazilwood."

Today, the brazilwood tree faces a hard job. In the 18th century, people harvested too many trees. This caused the wood trade to collapse. Now, the tree is an endangered species. This means there are very few left in their natural home. Some groups, like the International Pernambuco Conservation Initiative, are working to replant seedlings. They want to protect the tree for the future.

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.
