4. Rethymno region, Mt Psilorotis 3 km from the village Damasta to Marathos, maquis on a northeast facing slope, alt. 330 m. Dominant vascular plants: Calicotome villosa, Phlomis lanata, Pistacia lentiscus, Quercus coccifera, Sarcopoterium spinosum. 5. Lasithi region, around the cave Milatos at the village Milatos, phrygana on a west facing slope, alt. 150 m. Dominant vascular plants: Euphorbia acanthothamnos, E. dendroides, Phlomis lanata, Quercus coccifera, Salvia triloba. 6. Lasithi region, at the village Plaka near Elunda, phrygana on a south facing slope, alt. 50 m. Dominant vascular plants: Asphodelus aestivus, Calicotome villosa, Phlomis lanata, Pistacia lentiscus. The specimens collected during the study trip are deposited in the Hungarian Natural History Museum and the Natural History Museum of Crete. The floristical evaluation and comparison of the different maquis and phrygana stands were carried out using the European distribution of the bryophyte species according to DULL (1983, 1984, 1985) and bryophyte life strategy categories (DURING 1979, ORBÁN 1984). RESULTS In the stands investigated 19 liverworts, 47 mosses and 31 lichens were collected (Table 1). Three bryophyte species, new to Crete (as Weissia longifolia, W. rutilans, Funaria pulchella) and Petalophyllum ralfsii, a vulnerable species according the list of Red Data Book of European Bryophytes (SCHUMACKER, R. and MARTINY, PH. (1995), were collected in Rethymno region in the maquis stands of Mt Psiloritis. Four lichen species (Caloplaca carphinea, Cladonia cervicornis subsp. verticillata, Psora testacea and Xanthoparmelia tinctina) seem to be new to Crete. Acrocarpous mosses and xerotolerant thalloid liverworts have great importance in the species composition of the stands of Mediterranean vegetation type and they are represented by many species in the stands investigated. For example 21 taxa of Pottiaceae acrocarpous moss family and 5 taxa of Ricciaceae a drought tolerant thalloid liverwort family were found. The members of these groups avoid desiccation by the virtue of their morphological and anatomical features that promote water uptake or storage, or restrict water loss. On drying, the leaves or thallus become crisped, contorted to impede the water loss. In the Pottiaceae the leaves have recurved margins, papillose surfaces. The papillae and recurved leaf margin accelerate the spread of the water over leaf surfaces.
