This variety has a light chocolate-brown color, and the cubes are about an inch square, having an earthy fracture and external appearance. The other variety, Cutch, is of a darker color, rich brown, with a shining appearance and fracture, it comes much mixed with broken leaves, in which it has been laid to dry, it is packed in a similar manner to the Catechu, but is most generally run into one mass.

It is made by boiling the leaves and evaporating the decoction to dryness, in appearance it resembles Cutch, but it is not so glossy in its fracture, and rather lighter in color. It is mostly imported from Singapore, where it is extensively cultivated.

The Brazil-wood is cut from a tree about twenty feet high, with prickly branches and yellow flowers, the decoction yields, in dyeing, rose-color, red, and yellow, according to the mordant used.
