Bloodwood \Blood"wood\, n. (Bot.)
A tree having the wood or the sap of the color of blood.
[1913 Webster]
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).
