Abstract

Forty-three taxa of Eocene fossil pteridophytic palynomorphs were reported as an on-going effort to increase our knowledges of the Eocene microflora of Taiwan. They belong to two classes and twenty-one form genera; namely four form genera and six taxa for the class Monolete, and seventeen form genera and thirty-seven taxa for the class Trilete. Twenty new species (Gemmatosporis pengchiahsuensis sp. Nov.; Polypodiidites thunbergiensis sp. Nov.; Camarozono-sporites taiwanensis sp. Nov.; Gemmatriletes pengchiahsuensis sp. Nov.; Leiotriletes pengchia-hsuensis sp. Nov.; Lophotriletes pengchiahsuensis Shaw sp. Nov.; Punctatisporites taiwanensis sp. Nov.; Retitriletes pengchiahsuensis sp. Nov.; Sphagnumsporites pengchiahsuensis sp. Nov.; Toro-foveolatisporis pengchiahsuensis sp. Nov.; T. taiwanensis sp. Nov.; Triplanosporites pengchia-hsuensis sp. Nov.; T. granulatus sp. Nov.; Verrucingulatisporites pengchiahsuensis sp. Nov.; V. chinaensis sp. Nov.; V. minor. Sp. Nov.; V. creticus sp. Nov.; Verrucosisporites pengchiahsuensis sp. Nov.; V. wartus sp. Nov.; V. minutus sp. Nov. ), one new combination (Verrucingulatisporites fatangularis (Liu) comb. Nov.) were described from offshore Keelung in northern Taiwan.
