These areas being fairly moist exhibit a luxuriant growth and display of ferns whose number, however, is not very large. In all 22 species of ferns and fern allies belonging to 13 families have been classified according to their ecological habitat and enumerated with their important distinguishing characters and precise distribution. Names of species have been accompanied by only relevant synonyms. It is expressed that such a treatment is likely to be of considerable help for future collectors.
