A new genus and species of liverwort, Udaria lamellicaulis gen. & sp. nov., referable to the family Lophocoleaceae is described from Arunachal Pradesh and Sikkim in Eastern Himalaya, India. The new taxon can be easily differentiated from hitherto all the known genera of the family in the presence of longitudinal, 1-12 cells high seriately arranged lamelliform strips on the surface of stem, leaves and female bracts, striolate-rugulose leaf cuticle, rhizoids arising from the lamina of underleaves, gynoecia with 1-2 subfloral innovations and gemmiparous female bracts and bracteoles.
