It is a tree native to forests throughout Central and South America. This plant grows in the cerrado vegetation of Brazil, reaching up to French Guiana, Bolivia, Paraguay and Northern Argentina.[4]

It is one of the largest and strongest of tropical forest trees, growing up to 150 feet (46 m) tall while the base can be 4–7 feet (1.2–2.1 m) in diameter.[citation needed]

It is a commercially farmed hardwood notable for its extreme hardness[5] and resistance to fire and pests.[citation needed] It is sometimes traded as an "ironwood", or just as "ipê" (the entire genus Tabebuia),[4] or as lapacho (properly Handroanthus serratifolius)

Chemistry
