The research method used is descripting and purposive sampling. The results showed identification of diversity of Pteridophytes division in Ciwalen track Taman Nasional Gunung Gede Pangrango (TNGGP) found 10 species. The spesies among others: Asplenihm nidus, Asplenium spathulinum, Asplenium tereum, Diplazium proliferum, Didymochlena truncatula, Angiopteris evecta,, Cyclosorus subpubescens, Nephrolepis sp., Nephrolepis davallioides and Selaginella opaca ]]>
