The paper deals with the taxonomy and diversity within the genus Ficus occurring in Katerniaghat Wildlife Sanctuary based on extensive field and herbarium studies. The genus comprises 11 species in the study area contrary to the earlier report of 8 species. Out of which, one species each belongs to herbs (F. assamica) and straggling shrubs (F. hetero- phylla) and the remaining species to shrub to big free standing trees (F. benghalensis, F. hispida, F. palmata subsp. virgata, F. racemosa, F. religiosa, F. retusa var. nitida, F. rumphii, F. semicordata and F. squamosa). F. microcarpa and F. carica have been excluded as they do not occur in the sanctuary but reported in the previous work due to mis- identification. F. repens has been segregated from F. heterophylla and reinstated as a distinct species with a correct name F. assamica. F. retusa var. nitida forms a new record for the sanctuary. In overall gross morphology, F. hispida, F. palmata subsp. virgata, F. assamica and F. heterophylla exhibit maximum diversity especially in their leaves, pe- duncles and figs. Among all species F. hispida has been found more common especially in low land and moist areas in mixed forest whereas F. retusa var. nitida has been seen with only two plants. All species have been critically examined and provided with correct nomenclature, vernacular name, description, phenology, ecology, uses and reference to voucher specimens. A dichotomous bracketed key to the species along with line drawings has also been included for identification.
