Metopium brownei (also known as chechem or black poisonwood) is a species of plant in the Anacardiaceae family. It is found in the Dominican Republic, Cuba, Jamaica, northern Guatemala, Belize, Bonaire, Curacao, Aruba(rare) and from the Yucatán to Veracruz in Mexico. The wood of this tree is a valuable source of lumber in Central America and the West Indies. Like its cousin Florida Poisonwood (Metopium toxiferum), it produces urushiol in its bark, which can cause contact dermititis on one's skin when touched; therefore live trees and fresh cut logs should be handled carefully.
