Tahura Soerjo Forest Park has an altitude of 1456-1809 masl, temperature 18-22⁰C, humidity 32-77 is a suitable habitat for the epiphytic fern. The study was conducted in June-July 2019 in Tahura Soerjo Forest Park. Exploration includes 17 stations in the Cangar and Watu Ondo regions. The exploration results were Antrophyum reticulatum (Forst.) Kaulf, Athyrium esculentum (Retz) Copel, Belvisia revoluta (Bl.) Copel, Asplenium tenerum Forst. f, Asplenium tenuifolium D. Don, Asplenium decrescens Kunze, Asplenium zimkeranum Kunze, Vittaria elongata Sw, angustata Pyrrosia (Sw.) Ching, Hymenophillum gardneri vdb, Davallia trichumanoides Bl., Nephrolepis cordifolia (L.) Presl, Ctenupteris obliguata (Bl. ) Holtum, Crypsinus enervis (Cav.) Copel, Microsorium zippuli (Bi.) Ching, Monogramma trichoides J. Sm, Phymatodes nigrescens (Bl.) Sm. Morphologically, these epiphytic ferns have characteristics of upright rhizomes, crowded fronds, and live as a colony. Anatomic characteristics of the fronds are homogenous mesophiles, irregular epidermis, secretory trichomes, have kidney-type stomata, whereas in rhizomes have scalariform-type tracheids.
