The names of all mosses published up to the end of August 2011 in the countries of the Mediterranean basin, the Macaronesian Islands and Bulgaria are compiled in an annotated checklist. The list comprises accepted names and synonyms, and provides explanatory annotations for ambiguous and disputed names. Literature references supporting the reports in each individual area are given only for taxa reported once or in a single locality. A total of 1168 accepted species and 81 infraspecific taxa are reported from the whole area. Mosses / distribution / nomenclature / checklist / Mediterranean

The volatiles isolated by distillation-extraction from 48 samples of seven liverwort Radula species collected on Azores and Madeira archipelagos and mainland Portugal, as well as one from Switzerland, were analysed by GC and GC-MS. Cluster analysis of the volatiles composition resulted in two major clusters. The chemically very diverse cluster I included the oil samples of Radula aquilegia from Madeira, R. jonesii, R. holtii, R. nudicaulis, R. lindenbergiana as well as R. complanata from Switzerland. Cluster II was characterized by high relative amounts of several sesquiterpenes and included the oil samples of R. aquilegia from the Azores as well as R. carringtonii and R. wichurae. 3-Methoxy bibenzyl was the major oil component from R. complanata and R. lindenbergiana. Except for R. aquilegia and the closely related species R. complanata and R. lindenbergiana, the cluster analysis allows distinction of all studied species, indicating the chemotaxonomical value of the volatile oil characters.
