During th e summer of 1973, whil e touring islands of th e Aegean sea, I had the opportunity to make a small collection of bryophytes. Seventeen species of pottiaceous mosses are reported here, many being new records in th e literature for the majority of islands on which th ey were found. Several of th ese species are rare and are pr eviously unre­ported for Greece. Mosses of the famil y Pottiaceae are common along roadsides and pathways of the islands, th e dry climate appa rently not favoring the development of more hydrophilic species of bryophytes, except along watercourses.

Several papers, including tho se of Ade & Koppe (1955), Baum­gartner (1943, 1944), Brenan (1973) , Coppey (1907), Dull (1966) , Dull & Dull-Hermanns (1973) , Fro ehlich (1961), Gradstein (1970), Laflin (1973) , M edelius (1927), Nicholson (1907) Rungby (1967), Schiffner (1913, 1915), and Schiffner '& Baumgartner (1919), have been pub­lished reporting occasiona l bryophyte collections from th e Aegean islands. Most of these pap ers concern the bryoflora of Kriti, but other Greek islands of the Aegean for which bryophyte collections have been reported are Evvia, Dhilos, Kos, Karpathos, Lesvos (Mitilini) , Naxos, Rodhos, Samos, Samothraki, Thira (Santorini) Tinos, and Tilos. The pr esent pap er includes th e first report of br yophytes collected on th e island of Mikonos, of th e Kikladhes.

Geogr aphic relations of th e species listed here are pan-Mediterr a­nean . All of th e species have been found elsewhe re in th e Near East. Five of th e spec ies have not been previously reported for mainland Greece, but most of th e species are widely distributed in southern Europ e. One might estimate from th e sca nty lit erature th at any future intensive, systematic collecting on th e Aegean islands will uncover man y other species of mosses of M editerranean distribution not presently known for th e area.

In th e following account, th e numbers in th e specimen cita tions represent collec tions made by myself, in the company of my wife, K athe­rine Cha mes Zander. A set of th e spec ime ns are deposited in th e Clin­ton H erbarium (BU F) of th e Buffalo Museum of Scien ce, Buffalo, Ne w York Stat e, U SA. The nomenclature follows th at of Podpera (1954) .
