Croton lacciferum
Lac Lac, n. [Per. lak; akin to Skr. l[=a]ksh[=a]: cf. F. lague, It. & NL. lacca. Cf. {Lake} a color, {Lacquer}, {Litmus}.] A resinous substance produced mainly on the banyan tree, but to some extent on other trees, by the {Laccifer lacca} (formerly {Coccus lacca}), a scale-shaped insect, the female of which fixes herself on the bark, and exudes from the margin of her body this resinous substance. [1913 Webster]

Note: {Stick-lac} is the substance in its natural state, incrusting small twigs. When broken off, and the coloring matter partly removed, the granular residuum is called {seed-lac}. When melted, and reduced to a thin crust, it is called {shell-lac} or {shellac}. Lac is an important ingredient in sealing wax, dyes, varnishes, and lacquers. [1913 Webster]

{Ceylon lac}, a resinous exudation of the tree {Croton lacciferum}, resembling lac.

{Lac dye}, a scarlet dye obtained from stick-lac.

{Lac lake}, the coloring matter of lac dye when precipitated from its solutions by alum.

{Mexican lac}, an exudation of the tree {Croton Draco}. [1913 Webster]
