Ninety-seven taxa of Eocene fossil angiospermous palynomorphs were reported as an on-going effort to increase our knowledgs of the Eocene microflora of Taiwan. They belong to two classes, forty-nine families and sixty-seven form genera; namely sixty-five form genera and ninety-four taxa for the class Dicotyledoneae; and two form genera and three taxa for the class Monocotyledoneae.
