本文報導發現於台灣基隆北方海域始新世地層中，蕨類孢子化石共計四十三個形態屬；它們分別屬於二綱，二十一形態屬，其中Monolete綱計有四形態屬六形態種，Trilete綱計有十七形態屬三十七形態種，其中二十種為新種（Gemmatosporis pengchiahsuensis sp. nov.; Polypodiidites thunbergiensis sp. nov.; Camarozonosporites taiwanensis sp. nov.; Gemmatriletes pengchiahsuensis sp. nov.; Leiotriletes pengchiahsuensis sp. nov.; Lophotriletes pengchiahsuensis sp. nov.; Punctatisporites taiwanensis sp. nov.; Retitriletes pengchiahsuensis sp. nov.; Sphagnumsporites pengchiahsuensis Sp. nov.; Torofoveolatisporis pengchiahsuensis sp. nov.; T. taiwanensis sp. nov.; Triplanosporites pengchiahsuensis 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.），一種為新聚合種（Verrucingulatisporites fatangularis (Liu) comb. nov.）。

Forty-three taxa of Eocene fossil pteridophytic palynomorphs were reported as an ongoing effort to increase our know ledges 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.; Camarozonosporites taiwanensis sp. nov.; Gemmatriletes pengchiahsuensis sp. nov.; Leiotriletes pengchiahsuensis sp. nov.; Lophotriletes pengchiahsuensis Shaw sp. nov.: Punctatisporites taiwanensis sp. nov.; Retitriletes pengchiahsuensis sp. nov.; Sphagnumsporites pengchiahsuensis sp. nov.; Torofoveolatisporis pengchiahsuensis sp. nov.; T. taiwanensis sp. nov.: Triplanosporites pengchiahsuensis 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.
