Brazilwood (Caesalpinia echinata), valuable for its timber and colouring extract, and "roco" (Bixa orellana), the "urucn" of Brazil which furnishes the anatto of commerce, are widely distributed in central and southern Colombia, and another species of the first-named genus, the C. coariaria, produces the "divi-divi" of the Colombian export trade - a peculiarly shaped seed-pod, rich in tannic and gallic acids, and used for tanning leather.
The imports include wheat flour, rice, barley, prepared foods, sugar, coal, kerosene, beer, wines and liquors, railway equipment, machinery and general hardware, fence wire, cotton and other textiles, drugs, lumber, cement, paper, &c., while the exports comprise coffee, bananas, hides and skins, tobacco, precious metals, rubber, cabinet woods, divi-divi, dye-woods, vegetable ivory, Panama hats, orchids, vanilla, &c.

Although the plains are for the most part arid wastes, sugar, aloes, tobacco and divi-divi are produced with much toil in the more fertile glens.
