Anomodon rostratus, Rhynchostegiella teneriffae and Taxiphyllum densifolium. All of them are placed in the rare (R) category. Anomodon rostratus and Taxiphyllum densifolium were found on the limestone rocks in the dolinas between Ploce and Mali Strbac. The latter species has quite large populations here, numerous patches can be found in several dolinas. Anomodon rostratus was found in only one large dolina and in a few patches on a rock wall. Rhynchostegiella teneriffae was collected on the stones of Brnjicka reka stream. Two patches were found. According to the preliminary national red list of bryophytes (SABOVLJEVIC et al. 2004) the region of Djerdap National Park is rich in species of conservation interest. Among the liverworts, these are: Cephaloziella rubella (VU = vulnerable), Cololejeunea rossettiana (LR = lower risk), Leiocolea badensis (VU) and L. bantriensis (VU). Among the mosses, red-listed species are: Amphidium mougeotii (VU), Amblystegium confervoides (DD = data deficient), Anomodon longifolius (DD), A. rostratus (VU), Dicranella schreberiana (DD), Didymodon ferrugineus (DD), Fissidens exilis (DD), Orthotrichum obtusifolium (VU), Rhynchostegiella teneriffae (LR), Tortula papulosa (LR) and Tortula virescens (LR). Cephaloziella rubella seems to be rare in Serbia or under-recorded (only one unprecise previous record; GAJIC et al. 1991, SABOVLJEVIC 2000a). The presence of the species in Serbia was confirmed by PAPP et al. (2004) in Kopaonik Mts. This species occurs mainly in temperate to boreal ecosystems, and so this population at the border of its European area is of high conservation value. In SE Europe it possi-
