Saint Helena olive
The Saint Helena olive was a plant from the monotypic genus of flowering plants Nesiota within the family Rhamnaceae.
It was an island endemic native to Saint Helena in the South Atlantic Ocean. Despite its name, it is unrelated to the true olive. The last remaining tree in the wild died in 1994, and the last remaining individual in cultivation died in December 2003, despite conservation efforts. It is thus a prime example of recent species and genus extinction.
