Herbertus ramosus (Herbertaceae, Marchantiophyta) – an addition to Indian bryoflora from Arunachal Pradesh with a note on H. sendtneri

[摘要] Herbertus ramosus (Steph.) H.A.Mill. and H. sendtneri (Nees) Lindb. are described and illustrated from West Siang District of Arunachal Pradesh in the eastern Himalaya, India. This constitutes the first record of H. ramosus in Indian bryoflora. It is easily distinguished from hitherto known Indian species of the genus by orange brown plants having falcate leaves with acute leaf lobes 23–40 cells wide at base, up to 8 cells uniseriate towards apex, strongly expanded basal leaf lamina on dorsal side, and strong grooved vitta.
