Ferns (Pteridophyta) are one of the Indonesian flora groups with high diversity and wide distribution, one of which is in the montana zone, an ecosystem zone at an altitude of 1500-2400 m asl. Samiran Village is located in the District of Selo, Boyolali Regency, between two mountains, namely Mount Merapi and Mount Merbabu. This type of research was conducted at an altitude of 1600 m asl to 1800 m asl in Samiran Village, Selo District, Boyolali Regency.

Hall, Adiantum hispidulum Sw., Pityrogramma austroamericana Domin, Cyathea arborea L. Sm, Antrophyum sessilifolium (Cav.) Spr. The Diversity value (H') is 1.22, a category as relatively low. Ferns are most commonly found on soil hosts. The most abundant species were dominated by Adiantum raddianum C. Presl with 107 individuals at 14 out of 21 points. This species is one type of terrestrial fern that is also often found growing between rocks, pool walls, fences, wells, ditches, river banks other damp places. Therefore, this location is a suitable environment for the growth of Adiantum raddianum.
