Abstract: Epiphytic ferns were of interest for pteridologist in their diverse idioadaptations to withstand unfavorable conditions such as drought and substrate deficiency. Among many species, Drynaria quercifolia is one of the important fern the most serious threat for their life due to deforestation. In this aspect, tentative assessment of host variability and their composition were carried out in study area. The present study indicated that 11 species were reported as host species of D. quercifolia. Among these species Mangifera indica showed higher density of D. quercifolia compare to other 10 tree species. The D. quercifolia investigated here exhibit variation in their host with different tree species in Malnad region. Present data helpful in further research on D. quercifolia and future conservation steps.
