4000 Valjevo, P. O. Box 118, Yugoslavia Based on our recent research, the region of Petnica in W Serbia counts 136 bryophyte taxa (116 mosses and 20 liverworts). In the present account 15 species are reported for the first time in Serbia, and 11 for the F. R. of Yugoslavia. The 136 bryophyte species represent about 22% of the total number of bryophytes recorded up to now in the country. For the small area of Petnica, this means a very high level of diversity, which is the result of the great number and diversity of microhabitats. Among the bryophytes now on record, two species are European endemic, and three of them are included in the Red Data Book of European Bryophytes. Most bryophytes in the region are of temperate character, but considering the altitude of around 200 m above sea level, the specific position with considerable influence from the Mediterranean areas and the surrounding mountains, as well as the good hydrology with many peculiarities, we believe that some areas populated by the most interesting bryophytes should be declared protected areas (concept of microreserves). Key words: bryophyte flora, redlisted species, Serbia INTRODUCTION At present, the bryophyte flora of the Federal Republic of Yugoslavia (Serbia and Montenegro) is very poorly known. Bryology and bryophyte research had been a neglected area of botany for many decades. This explains the small number of the investigated regions and that the number of recorded species is relatively low. To date, the bryophyte flora of the F. R. of Yugoslavia counts 118 hepatic and 511 moss species, respectively (SABOVLJEVIC and STEVANOVIC 1999, SABOVLJEVIC 2000). However, as more investigations take place, more and more species appear as new for the region (SABOVLJEVIC 1998, SABOVLJEVIC and STEVANOVIC 2000a, b).
