The terricolous and saxicolous bryophyte vegetation of the Jbel Bouhalla (western Rif Cordillera, Morocco) has been studied using the Zurich-Montpellier School's method. 14 communities have been recognized. Two associations from southern Iberian Peninsula and Morocco are described as new: Cephaloziello turneri-Claopodietum whippleani ass. nova of acidic taluses and ledges and Pleuridio acuminati-Acauletum mediterranei ass. nova which grow on acidic, dry soils with clayey texture. The latter association is included in a new alliance Cheilothelion chloropi al. nova belonging to the class Dicranelletea heteromallae which includes the terricolous and acidic communities with a Mediterranean behaviour. Conclusions from field observations about the dynamics of the communities were undertaken.
