| Columbia Encyclopedia: logwood |
logwood, small, thorny tree (Haematoxylon campechianum) of the family Leguminosae (pulse family) native to tropical America and introduced into other tropical regions. The brown-red heartwood is the source of the dye haematoxylin and was exported to Europe as a major purple textile dye from the 16th cent. until the development of synthetic aniline dyes. It is still used more than are most natural dyes—as a histological stain, for ink, and as a special-purpose dye. Local names for the wood include campeachy wood and blackwood. The name logwood is sometimes applied to other similar woods. Logwood is classified in the division Magnoliophyta, class Magnoliopsida, order Rosales, family Leguminosae.

Logwood (Haematoxylum campechianum) is a species of flowering tree in the legume family, Fabaceae, that is native to southern Mexico and northern Central America.[1] It has been and to a lesser extent remains of great economic importance. The modern nation of Belize grew from 17th century English logwood logging camps. The tree's scientific name means "bloodwood" (haima being Greek for blood and xulon for wood).
Uses
Logwood was used for a long time as a natural source of dye, and still remains an importance source of haematoxylin, which is used in histology for staining. The bark and leaves are also used in various medical applications. In its time, logwood was considered a versatile dye, and was widely used on textiles but also for paper.[2] The dye's colour depends on the mordant used as well as the pH. It is reddish in an acidic environments but bluish in alkaline ones.[2]
