Leaf_old fustic

Description

Maclura tinctoria, commonly known as old fustic or 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.[citation needed] This dye contains the flavonoid morin. The leaves can be used to feed silk worms.Old fustic is not to be confused with young fustic (Rhus cotinus) from southern Europe and Asia, which provides a more fugitive colour.
