Paubrasilia echinata is a species of

heartwood that takes a high shine, and it is the premier wood used for making bows for stringed instruments.[5][8] The wood also yields a historically important red dye called brazilin, which oxidizes to brazilein.[9]

The name pau-brasil was applied to certain species of the

scientific name Caesalpinia echinata in 1785 by Jean-Baptiste Lamarck.[3] More recent taxonomic studies have suggested that it merits recognition as a separate genus, and it was thus renamed Paubrasilia echinata in 2016.[3] 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).[10]

The name of Brazil is a shortened form of Terra do Brasil, 'land of brazilwood'.[11]

Name

When

sappanwood
already used in Europe for producing red dye. The Portuguese named these trees pau-brasil, the term pau meaning wood, and brasil meaning reddish/ember-like. The South American trees soon dominated trading as a better source of dye. Such a vigorous trade resulted from the woods that early sailors and merchants started referring to the land itself as Terra do Brasil, or simply, the "Land of Brazil", and from this use the present name of Brazil was derived.

Botanically, several tree species are involved, all in the family

Caesalpinia sappan and Haematoxylum brasiletto. The tree is also known by other names, such as ibirapitanga, from Tupi, meaning "reddish wood";[7] or pau de pernambuco, named after the Brazilian state of Pernambuco
.

In the bow-making business it is usual to refer to some species other than Paubrasilia echinata as "brazilwood"; examples include pink ipê (Handroanthus impetiginosus), Massaranduba (Manilkara bidentata) and palo brasil (Haematoxylum brasiletto). The highly prized Paubrasilia echinata is usually called "Pernambuco wood" in this particular context.

Description

The brazilwood tree may reach up to 15 metres (49 ft) in height, and the dark brown bark flakes in large patches, revealing the lustrous blood-red sapwood underneath. The leaves are pinnate and each consists of between 9 and 19 small, leathery leaflets, which are broadly oblong in shape.[12] The flower stalk, or inflorescence, is also branched and contains between 15 and 40 yellow, strongly perfumed flowers,[12] which may be pollinated by bees.[12] The petals are usually yellow with a blood-red blotch.[12] The fruits are oval-shaped woody seedpods, measuring up to 7.3 centimetres (2.9 in) long and 2.6 centimetres (1.0 in) across; they hang off the branches and after the seeds are expelled, the pods become twisted.[12] The branches, leaves and fruit are covered with small thorns.[12]

There are some important differences between geographically distinct populations and it is thought that separate subspecies of the pau brasil may exist.[12] This tree may have some medicinal properties and has been used as an astringent and antidiuretic by local people; extracts have been tested as possible cancer treatments.[12]

Historical importance

Starting in the 16th century, brazilwood became highly valued in Europe

textiles, such as velvet, in high demand during the Renaissance. When Portuguese navigators landed in present-day Brazil, on April 22, 1500, they immediately saw that brazilwood was extremely abundant along the coast and in its hinterland, along the rivers. In a few years, a hectic and very profitable operation for felling and shipping all the brazilwood logs they could get was established, as a crown-granted Portuguese monopoly. The rich commerce which soon followed stimulated other nations to try to harvest and smuggle brazilwood contraband out of Brazil, and corsairs to attack loaded Portuguese ships in order to steal their cargo. For example, the unsuccessful attempt in 1555 of a French expedition led by Nicolas Durand de Villegaignon, vice-admiral of Brittany and corsair under the King, to establish a colony in present-day Rio de Janeiro (France Antarctique) was motivated in part by the bounty generated by economic exploitation of brazilwood. In addition, this plant is also cited in Flora Brasiliensis by Carl Friedrich Philipp von Martius
.

Excessive harvesting

Excessive harvesting led to a steep decrease in the number of brazilwood trees in the 18th century, causing the collapse of this economic activity. Presently, the species is nearly

official list of endangered flora of Brazil
.

and composite bow industry to thrive.

Replanting efforts

Restoration of the species in the wild is hampered by the fact that it is a climax community species, which will develop well only when planted amongst secondary forest vegetation.[15] Although many saplings have been distributed or sold during recent decades, that has led to the tree being planted in places outside its natural range, with somewhat poor results, such as happens with brazilwood trees used for urban landscaping in the city of São Paulo, whose development and flowering is usually hampered by the colder environment.[16]
