Filicinae (genuine ferns) is one of the classes of Pteridophytes with the most species that exist and spread in Indonesia. Consequently, there will be feasibility of different classifications for the same types. To avoid this activity, a special effort is needed to facilitate the classification process. One of those efforts is the analysis of phenetic kinship which emphasized in the concept of taxonomic characters, types of characters, and the number of characters used.  Besides, it also offers scientific and explicit procedures for the classification phase.  This study aimed to answer the questions of how phenetic kinship of eight types of filicinae based on the morphological and anatomical characteristics. For methodology, this study used a descriptive qualitative approach by employing survey. The objects of this study were eight types of ferns in filicinae class. The data was collected in August 2018. Research parameters were morphological and anatomical characteristic of filicinae (ferns). For data species of ferns, the morphological and anatomical were analyzed descriptively and presented by pictures and tabulation. Moreover, for taxonomic range data was analyzed using JK formula and for the kinship data was analyzed using Cluster Analysis which presented in Phenogram. As result findings, eight types of ferns in filicinae class have seven clusters (combinations). The closest kinship was shown in the species of Nephrolepis cordifolia (L.) Schott. and Nephrolepis biserrata (Sw.) Schott. Furthermore, the second closest is displayed in the species of Nephrolepis cordifolia (L.) Schott., Nephrolepis biserrata (Sw.) Schott., and Davallia denticulata (Burm. F) ex. Kuhn. Meanwhile, for the third closest was shown in the species of Drynaria bonni. Crist., Adiantum caudatum L. And for the farthest kinship was presented in the species of Nephrolepis cordifolia (L.) Schott., Nephrolepis biserrata (Sw.) Schott., Davallia denticulata (Burm. F) ex. Kuhn., Pteris vitata L., Pyrrosia piloseloides (L.) M.G. Price., and Drynaria bonni. Crist., Adiantum caudatum L., Crypsinus enervis (Cav.) Copel. Therefore, it can be inferred that both species which have the smallest taxonomic range produced equal features and characteristics neither in morphological nor anatomy.
