George Poinar has studied amber for many years and he and his wife Roberta founded “The Amber Institute” that provided information and identifications of amber inclusions. The Institute was closed after the Poinars left UC Berkeley and went to Oregon State University. A paper written by the Poinars showed Michel Crichton a way to bring back dinosaurs in his book “Jurassic Park”. After studying animals in amber, Poinar and his colleagues began investigating flowers. The descriptions of all amber flowers, including those of the trees that produced Dominican and Mexican amber, are summarized in the present work.
