Bluewood or Logwood Tree

Its leaves are dry and leathery, obovate, entire, and scarcely an inch long. Its twigs end in sharp thorns. The sweet berries ripen, turning blue, then black, during the long summer. The wood is red, but yields a bluish dye.
It is an entirely different tree from the logwood of commerce, Haema-toxylon Campechianum, which grows in Central America and the West Indies and yields a colouring matter used in calico printing and in the preparation of lake pigments.
