What is "maclura tinctoria"

Morintannic \Mo`rin*tan"nic\, a. [NL. Morus fustic + E. tannic.] (Chem.) Pertaining to, or designating, a variety of tannic acid extracted from fustic ( Chlorophora tinctoria, formerly Maclura tinctoria and Morus tinctoria) as a yellow crystalline substance; -- called also maclurin.

Fustic \Fus"tic\, n. [F. fustoc, Sp. fustoc. Cf. Fustet.] The wood of the Maclura tinctoria, a tree growing in the West Indies, used in dyeing yellow; -- called also old fustic. [Written also fustoc.]

Note: Other kinds of yellow wood are often called fustic; as that of species of Xanthoxylum, and especially the Rhus Cotinus, which is sometimes called young fustic to distinguish it from the Maclura. See Fustet.

Morin \Mo"rin\, n. (Chem.) A yellow crystalline substance ( C15H10O7) of acid properties extracted from fustic ( Chlorophora tinctoria syn. Maclura tinctoria, formerly called Morus tinctoria); -- called also moric acid and natural yellow 8. It is used as a dye for wool, giving a color from lemon yellow through olive to olive brown, depending on the metal with which it is mordanted.

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. 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.
