areas); and (iii) calcareous fens (habitat code 7210, 13 areas). Raised bogs and calcareous fens are included in the priority habitat types of the Habitat Directive of the European Union (Annex I, 92/43/EEC) (DAFIS et al. 1996). There are only two active (and very small-sized) bogs recorded in Greece: (i) the previously mentioned one at "Kali Pediada" (Mt Voras, Prefecture Pella), and (ii) at "Elatia" (in the Rhodope mountain range, Drama Prefecture). Methods A short visit was made to Mt Voras (30-31.08.2000), previously known for the presence of Sphagnum species (ATHANASIADIS 1977). Two alkaline fens with Sphagnum species were visited (Fig. 1); both were situated in open areas. The first is located at the "Voras-Kaimaktsalan ski centre", about half a kilometre before the chalet (N of Agios Athanasios village). There were no previous collections from here before. The second is the active bog at the area of "Kali Pediada" (NW of Loutraki) by the country's northern border line, which is considered as the largest active bog in Greece (DAFIS et al. 1996), and it is the collection area named "Kampos" mentioned by ATHANASIADIS (1977). All alkaline fens in Greece {Carex davalliana dominated) are reported mainly from high altitudes, from the mountainous areas of Macedonia and the Pindos mountain range (e.g. Smolikas, Agrafa and Aspropotamos Mts). Both areas are situated in North Greece, Central Macedonia District, Pella Prefecture, Mt Voras. The exact coordinates are: Site 1 : Lat.: 40° 54' 32" N; Long.: 21° 48' 40" E, Alt.: 2,050 m a.s.l. Site 2: Lat.: 41° 02' 14" N; Long.: 21° 53' 30" E, Alt.: 1,750 m a.s.l. Around Site 1 there are alpine and subalpine heaths. Species-rich Nardus grasslands growing on siliceous substrates, Fagus sylvatica forests with Abies borisii-regis, nitrophilous (Asperulo-Fagetum) and acidophilous (Luzulo-Fagetum) beech forests and black pine stands of Pinus nigra subsp. pallasiana forests are also found in the surroundings. Site 2 is surrounded by subalpine and alpine tall herb communities; in the broader area species-rich Nardus grasslands grow on siliceous substrates, along with alpine and subalpine heaths and reforested mountain slopes with acidophilous (Luzulo-Fagetum) and nitrophilous (Asperulo-Fagetum) beech forests. The specimens collected have been deposited in the Herbarium of the Hungarian Natural History Museum, Budapest (BP), and in the Herbarium of the Aristotle University of Thessaloniki (TAU). Nomenclature and the European distribution data follow DULL and MEINUNGER (1989) and DULL (1995). The floristical results have been analysed according the latest available check-list of DULL (1995), updated with all the new records for Greece. For the distribution of bryophyte taxa the floristical regions of Greece are used, according to the "Flora Hellenica" project (STRID and TAN 1997) with the differentiation accepted for bryophytes by PRESTON (1981). The abbreviations used for the Greek floristical areas and their definitions are the following: CR (Crete), RH (Rhodos island), AE: Th (Aegean islands: Thasos), IO (Ionian islands), PE (Peloponnisos), ST (Sterea Hellas), EU (Euboea), PI (Pindos), EC (East Central), NC (North Central, Thessalia), NE: At, Ch, Rd (North East: Athos, Chalkidiki, Rhodope Mts).
