Phenetic kinship of eight ferns from Filicinae class based on morphological and anatomical characteristic

Filicinae is one of the Pteridophyta class with the most species. Thus, the different classification may occur for the same type. Consequently, it is necessary to simplify the classification; one of them is through phenetic kinship analysis. This study aims to identify phenetic kinship of eight ferns from filicinae class based on morphological and anatomical characteristics. The study applied descriptive and survey methods with a qualitative approach. Data was collected in August 2018 and analyzed using an Analysis Cluster method which is presented in the form of a phenogram. The finding suggests that 7 clusters are formed from 8 species of ferns from filicinae class. The closest kinship is shown in the species of Nephrolepis cordifolia (L.) Schott and Nephrolepis biserrata (Sw.) Schott which indicates that both species with the smallest taxonomic distance value have similar morphological and anatomical characters; while the furthest kinship is the species of Nephrolepis cordifolia (L.) Schott, Nephrolepis biserrata (Sw.) Schott., Davalia denticulata (Burm. F) ex. Kuhn., Pteris vitata L., Pyrrosia piloseloides (L.) M.G. Price., and Drynaria bonni.
