The heartwood of a tree ({H[ae]matoxylon Campechianum}), a
native of South America, It is a red, heavy wood, containing
a crystalline substance called h[ae]matoxylin, and is used
largely in dyeing. An extract from this wood is used in

A tree having the wood or the sap of the color of blood.

Note: Norfolk Island bloodwood is a euphorbiaceous tree
({Baloghia lucida}), from which the sap is collected
for use as a plant. Various other trees have the name,
chiefly on account of the color of the wood, as
{Gordonia H[ae]matoxylon} of Jamaica, and several
species of Australian {Eucalyptus}; also the true
logwood ({ H[ae]matoxylon campechianum}).
[1913 Webster]
