   straight, black, upright trunk, with palmate leaves. It is

   Ocean, from the mouth of the Tigris to New Guinea. More than
   eight hundred uses to which it is put are enumerated by
   native writers. Its wood is largely used for building
   purposes; its fruit and roots serve for food, its sap for
   making toddy, and its leaves for thatching huts.
