%X The stratigraphic occurences of 3 classes, 44 form genera, 104 species and varieties of the Miocene fossil Pteridophytic spores from the sediments of the North Taiwan including the Miocene formations on the western flank of the Chuhuangkeng section of Miaoli-hsien, Keelung-Yehliu section and Taipei-Sanhsia section of Taipei-hsien were obtained. Nine new species and three new records were also proposed.
The distributional range of these 104 pteridophytic spore taxa in 82 samples have been investigated, then ten useful biostratigraphy events can be recognized.  Based on those ten events, the Miocene sediments of Taiwan can be subdivided into nine spore zones. These spore zones have a close correlation with rock units.
The fossil sporomorphs which appeared at first time in rock units, decreased its numbers gradually from the oldest to youngest rock formations. From the amount of the Magnastriatites in the different rock units, the habitats of the youngest rock formations of Kueichulin and Nanchuang were dry, and the Kuanyinshan Sandstone was swamp and the older rock formations showed repeatedly alternative swamp and dry conditions.
