Understanding the morphology of pteridophyte spores provides fundamental information needed to study their biological distribution patterns. The present study investigates pteridophyte spore morphology by studying physical traits including structure dimensions in addition to shape features and colour variations and surface markings. A taxonomic examination reveals that observed spores belong to two different groups that either demonstrate advanced monolete morphologies or primitive trilete characteristics with individual spore measurements ranging between 15 µm and 150 µm. Clusters of Pyrossia porosa megaspores reached the largest dimensions at 70×95 micrometers whereas Polystichum aculeatum possessed the smallest spores sized at 21×26 micrometers. Surface ornamentation in spore structure mainly depends on exine and perine. Researchers detected numerous surface ornamentations as reticulate, regulate, cristate, folded, granulate, perforate, rugate, tuberculate and verrucate patterns. Median monolete advanced morphology was observed in 29 out of the 35 plant species identified during the study although trilete basic morphology was found in twelve different species. The systematic importance of features derives from spores in fern classification
