gal) it is reported from the east Mediterranean, too e.g. Italy, Greece, former Yugoslavia (DULL 1984). It seems to be a frequent species within the Mediterranean region growing on basic rock fissures, soils in shadow, in woods and by rivulets. It can be confused with robust forms of F. adianthoides, from which it differs with its longer leaves, smaller and mamillose leaf cells. Schistidium singarense (Schiffn.) Laz. is a member of the S. apocarpum complex. It grows mainly on basic rocks in a wide altitudinal range. This species seems to be a quite common species of the genus in the Mediterranean region as in Spain, Italy, Montenegro (CORTINIPEDROTTI 2001, SABOVLJEVIC, 2001 and CASAS 2000), along with another closely related species from the S. apocarpum complex, S. crassipüum Blom. BRYOFLORISTICAL NOTES In accordance with the phytogeographical situation of Turkish Thrace most (40%) of the species collected are taxa of the temperate zone of Europe. Most of these are circumpolar elements, but a few of them have Euro-Asiatic distribution as Frullania dilatata, Isothecium alopecuroides, Scleropodium purum, A high proportion of the species has subatlantic, sub-Mediterranean distribution (37%). Among liverworts, 7 species from the total 17 are of Mediterranean elements e.g. Calypogeia fissa, Cephaloziella haumgartnerii, C turne ri, Fossombronia angulosa, Lophozia turbinata, Riccia crozalsii, R. nigrella. Several characteristic mosses of the Mediterranean region were also collected, including Cheilothela chloropus, Dicranella howei, Fissidens limbatus, Homalothecium aureum, Rhynchostegiella tenella var. litorea, Scorpiurium circinatum, Tortella nitida, Tortula ruralis subsp. hirsuta. A few rarer Mediterranean species e.g. Tortula marginta, T. solmsii could also be highlighted. Some boreal, subboreal elements (11 species) contribute to the diversity of the flora according to the collected material e.g. Scapania irrigua, Bartramia ithyphylla, Bryum pollens, Dicranum majus, D. scoparium, Ditrichum flexicaule, Gymnostomum aeruginosum, Hygrohypnum luridum, Orthotrichum pollens, Pylaisiella polyantha, Tortula subulata.
