From Wikipedia, the free encyclopedia
Pisonia is a genus of plants. Some species, for example Pisonia brunoniana of New Zealand, Norfolk Island, Lord Howe Island and Hawaii, Pisonia umbellifera, and possibly Pisonia grandis widespread in the tropical Indo-Pacific region, are referred to as Birdcatcher or Catchbird trees because their sticky seeds reportedly trap small birds. Such sticky seeds are postulated to be an evolutionary feature of some island species for adherence of their seeds to birds; thereby facilitating distribution of seeds between islands.
