Abstract

The genus Radula is represented in Madeira Archipelago by seven species and by four species in mainland Portugal. Present known distributions are presented, for each of the mentioned arreas, R. aquilegia, R. carringtonii, R. complanata, R. holtii, R. jonesii, R. lindenbergiana, R. nudicaulis and R. wichurae. Notes on habitat preferences and conservation status are also given for the eight species considered. In this work it is alsao suggested that R. aquilegia should be excluded from the mainland Portugese bryophyre flora.
