A new liverwort species, Lejeunea masamiana G.E.Lee & Pócs, is described and illustrated from Indonesian New Guinea. It is recognised by the strongly recurved to involuted leaves both in dry and moist condition, leaf cells with well-developed trigones and with conspicuous intermediate thickenings, smooth cuticle, fully incurved free margin of the lobule, and large, reniform underleaves with frequently recurved margins and with lobes up to 1/4 of underleaf length. Morphological variations of some liverwort species due to environmental effect of the forest in New Guinea are discussed, as a factor which might have influenced also the morphology of the new species.
