Additions to the distribution of some Palaeotropic Lejeunea (Marchantiophyta) species, with the description of Lejeunea konratii sp. nov. from Fiji

Abstract

Three new additions to the knowledge of Lejeunea species in the Paleotropical bryoflora with their distributional ranges are presented. A new species, Lejeunea konratii G.E.Lee & Pócs, from Fiji (Central Viti Levu) is described and illustrated. It is characterized by the peculiar (1)–2 cells long first tooth of leaf lobules, the robust stem with 16–24 epidermal cells and ventral merophytes 4–8 cells wide, the reniform underleaves, the smooth cuticle, the leaf cells without well-developed trigones and intermediate thickenings, and the 2-winged, auriculate and undulate keels of the perianth. All Asian and Pacific species of Lejeunea with pluricellular lobule teeth are compared and discussed.
