INDIGO

n.[L. indicum, from India. ] A substance or dye, prepared from the leaves and stalks of the indigo-plant, which are steeped in water till the pulp is extracted, when the tincture is drawn off and churned or agitated, till the dye begins to granulate. The flakes are then left to settle; the liquor is drawn off, and the indigo is drained in bags and dried in boxes. It is used for dyeing blue.

 

INDIGOMETER

INDIGO-PLANT

n.A plant of the genus Indigofera, from which is prepared indigo. It is a native of Asia, Africa and America, and called by the native Americans, anil. The calyx is patent; the carina of the corol is furnished with a subulate, patulous spur on each side; the legume or pod is linear. Several species are cultivated for making indigo, of which the most important are the tinctoria, or common indigoplant, the anil, a larger species, and the disperma, which furnishes the Guatimala indigo.
