Description
The brazilwood tree may reach up to 15 metres in height, and the dark brown bark flakes in large patches, revealing the lustrous blood-red heartwood underneath. The leaves are pinnate and each consists of between 9 and 19 small, leathery leaflets, which are broadly oblong in shape. The flower stalk, or inflorescence, is also branched and contains between 15 and 40 yellow, strongly perfumed flowers, which may be pollinated by bees. The petals are usually yellow with a blood-red blotch. The fruits are oval-shaped woody seedpods, measuring up to 7.3 cm long and 2.6 cm across; they hang off the branches and after the seeds are expelled, the pods become twisted in shape. The branches, leaves and fruit are covered with small thorns.
There are some important differences between geographically distinct populations and it is thought that separate subspecies of the pau brasil may exist. 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.

—George Gordon Noel Byron (1788–1824)
“The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.”
