Maclura tinctoria

Species of tree

Maclura tinctoria, known as old fustic and dyer's mulberry, is a medium to large tree of the Neotropics, from Mexico to Argentina. It produces a yellow dye called fustic primarily known for coloring khaki fabric for U.S. military apparel during World War I. This dye contains the flavonoid morin. It is dioecious, so both male and female plants are needed to set seed.
