A total of 56 species were recorded, belonging to 18 families and 36 genera. Of these species, 50 are ferns and 6 are lycophytes. The highest number of species was observed in Sumugot (42 species) followed by Frankfort (26 species). Thirty-one species are terrestrial, 19 are epiphytes, 1 tree fern and 5 species have more than one growth form. The number of species is approximately about 5% and 9% of the total number of pteridophytes species in the Philippines and Mindanao, respectively.
