Contribution à l’étude de la bryoflore du massif de la Sainte-Baume (Bouches-du-Rhône et Var)

Prospecting carried out on limestone or dolomite at the Sainte-Baume and in other points of the massif (vicinity of Gemenos, Saint-Zacharie, Nans-Les-Pins and Mazaugues) yielded 160 species of mosses and 27 species of liverworts. Respectively 61 and 7 of them had never been reported before from the study area. The presence of 27 orophilous bryophytes which are very rare in the lowlands of the Provence, most of them found only at the Sainte-Baume, is emphasized. Cryphaea heteromalla, Dicranum tauricum, Didymodon rigidulus, D. spadiceus, Ditrichum crispatissimum, Encalypta trachymitria, Gymnostomum lanceolatum, Hymenostylium recurvirostrum, Mnium ambiguum, Schistidium crassipilum, S. singarense, Seligeria recurvata and Tortula handelii var. handelii are new records for the department Var, while Aschisma carniolicum has to be added to the bryoflora of the Bouches-du-Rhône.
