   note: the finest black ebony is the heartwood of diospyros
         reticulata, of the mauritius. other species of the
         same genus d. ebenum, melanoxylon, etc., furnish
         the ebony of the east indies and ceylon. the west
         indian green ebony is from a leguminous tree brya
         ebenus, and from the excaecaria glandulosa.
