Map of the study area indicating the abbreviation used the countries and islands for whicha separate list is included in the checklist (cf. also Table 1).The lengthy duration of the project is explained by its complexity and thefact that the members of the OPTIMA Bryophyte Commission had otherconcurrent activities and responsibilities. However the experience gained duringthe project will serve as a sound basis for the checklist of mosses still to beproduced.Criteria for the list of accepted namesTaxonomy and NomenclatureThe list includes published names and records to the end of May 2007.The checklist by Grolle & Long (2000) was the basic reference work for acceptednames in Europe and Macaronesia. We have made some exceptions to this list inthe light of more recently published taxonomic papers, and we have added thenames of taxa from African and Asian countries that were outside the geographicalscope of Grolle & Long’s list. We have also included some names that are notcited in Grolle & Long’s list in view of their frequent use in Mediterranean areasand the lack of consensus in recent literature on their taxonomic value. For example,Grolle & Long (2000) cited very few infra-specific names. We took the viewthat the varieties and subspecies of some polymorphic taxa that have been recognizedin relatively recent studies merited inclusion (e.g., those of Bazzania trilobata(L.) Gray, Blepharostoma trichophyllum (L.) Dumort., Jubula hutchinsiae(Hook.) Dumort., Marchantia polymorpha L. and several species of Riccia ). Incases where infraspecific taxa have not been distinguished in the literature for a
