The Cumbum Valley and Pachakumatchi Hills are situated to the south-west of Madurai Town and lie between 77°12' and 77°30' E and 9°30' and 9°50' N. Three seasonal explorations were conducted in the months of June 1959, October 1959 and April 1960. The Pteridophyte vegetation is rich in the Pachakumatchi Hills where the humidity is high and the altitude reaches 1600 m. A total number of 50 species representing 14 families and 35 genera were collected and enumerated. The classification of Copeland is followed.
