Conservation
The species Gahnia lanaiensis has been known as a rare endemic plant from the Hawaiian island of Lanai and it was federally listed as an endangered species of the United States. In 2010, however, research suggested that the Lanai plants are actually Gahnia lacera introduced from New Zealand in the early 20th century.[ 7]
