With the sixth volume of 'Bryophyte locality data from the Near and Middle East' (Pottiaceae “Eucladium – Z” till Trachypodaceae ; families in alphabetical order), consequently all published data of mosses between are presented to provide ‒ in addition to volume 5 (Neckeraceae till Pottiaceae “A – Didymodon”) ‒ a complete data base and background for the whole area. Starting with the beginning of the collection activities (e.g., Forsskål 1775) it covers the whole period till the end of 2019 and is the first comprehensive catalogue for these organisms including Afghanistan, Bahrain, Iran, Iraq, Israel, Jordan, Kuwait, Lebanon, Oman, Qatar, Saudi Arabia, Sinai Peninsula, Syria, Turkey, United Arab Emirates and Yemen (incl. Socotra). With the sixth volume, the catalogue of 'Bryophyte locality data from the Near and Middle East' allows an easy access to what is recorded and known from the different countries of the Near and Middle East.

With the first volume of 'Bryophyte locality data from the Near and Middle East', all published data of hornworts (Anthocerotophyta) and liverworts (Marchantiophyta) are presented to provide a solid data base and background for the whole area. Starting with the beginning of the collection activities (e.g., Forsskål 1775) it covers the whole period till the end of 2019. It is the first comprehensive catalogue for these organisms including Afghanistan, Bahrain, Iran, Iraq, Israel, Jordan, Kuwait, Lebanon, Oman, Qatar, Saudi Arabia, Sinai Peninsula, Syria, Turkey, United Arab Emirates and Yemen (incl. Socotra). Knowledge of species and its distribution is essential for floristic inventories, species catalogues, and further tools such as community structure, composition, biomonitoring, nature conservation, life history traits (morphological, anatomical and physiological adaptations), biochemical compounds (secondary metabolits, antimycotica). In addition, species distribution and occurrence today and in former time, is of basic importance in understanding plant diversity and eco-system processes, development, function and changes, especially with regard to the present increasing human influence and global warming and future tools. Although hornworts and liverworts belong to a group of mostly very small organisms that often are neglected and/or overlooked, they play an important and outstanding role in many habitats in nearly all countries and landscapes of the Near and Middle East as they are found in the understory of forests and woodlands, as pioneers on soil and rock, in steppes and deserts (organisms of "harsh environment"), in swampy areas and bogs, or as epiphytes on tree trunks. As scientific interest in plant diversity drastically increases recently, the ongoing interest stimulated us, to prepare this kind of data base to provide a solid background of what is known in the different countries of the Near and Middle East. It is a further step to integrate this large area into the Global Network of floristic knowledge and the tools of the Global Strategy for Plant Conservation.

With the third volume of 'Bryophyte locality data from the Near and Middle East' (Bruchiaceae till Funariaceae; families in alphabetical order), consequently all published data of mosses between are presented to provide ‒ in addition to volume 2 (Amblystegiaceae till Brachytheciaceae) ‒ a complete data base and background for the whole area. Starting with the beginning of the collection activities (e.g., Forsskål 1775) it covers the whole period till the end of 2019 and is the first comprehensive catalogue for these organisms including Afghanistan, Bahrain, Iran, Iraq, Israel, Jordan, Kuwait, Lebanon, Oman, Qatar, Saudi Arabia, Sinai Peninsula, Syria, Turkey, United Arab Emirates and Yemen (incl. Socotra). With the third volume, the catalogue of 'Bryophyte locality data from the Near and Middle East' allows an easy access to what is recorded and known from the different countries of the Near and Middle East.

With the second volume of 'Bryophyte locality data from the Near and Middle East', (Amblystegiaceae till Brachytheciaceae; families in alphabetical order) consequently all published data of mosses are presented to provide a complete data base and background for the whole area.

Starting with the beginning of the collection activities (e.g., Forsskål 1775) it covers the whole period till the end of 2019 and is the first comprehensive catalogue for these organisms including Afghanistan, Bahrain, Iran, Iraq, Israel, Jordan, Kuwait, Lebanon, Oman, Qatar, Saudi Arabia, Sinai Peninsula, Syria, Turkey, United Arab Emirates and Yemen (incl. Socotra). With the fifth volume, the catalogue of 'Bryophyte locality data from the Near and Middle East' allows an easy access to what is recorded and known from the different countries of the Near and Middle East.

This book describes and illustrates in detail the 760 species of mosses currently known to occur in the British Isles and incorporates the most up-to-date information available on classification and nomenclature, together with recent synonyms. The species descriptions provide information on frequency, ecology, geographical relationships and distribution, including information on protected species and those species at risk. For many species there are footnotes to aid identification. In addition to the species descriptions there are descriptions of families and genera and also introductory information on conservation, collection, preservation and examination of material, together with advice on using the keys. An artificial key to genera provides the only workable comprehensive key published in the English language. This second edition incorporates the very considerable advances in our knowledge of mosses made in the last quarter of the twentieth century and will provide a unique resource for all concerned with these fascinating organisms.
