Abstract: The Gentianaceae family represents 33 species of plants belonging to nine genera with a sub species reported in India. The studies on diversity, distribution and phenology of this family in montane grasslands of Karnataka have been under taken. A total of 60 quadrats of 50 m line transect with alternate 1×1 m subquadrats were laid for enumeration. A total of 12 species of the family Gentianaceae were occurred. Where, Swertialawii is one of the dominant species in the study area. Important value index (IVI) of S. lawii represents 50.62. Most of these species are restricted in distribution particular habitat and they are highly seasonal. All these species are in threatened condition due to anthoprogecinc pressure.
