Bloodwood \Blood"wood\, n. (Bot.)
   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}).
