Some additions to the bryophyte flora of the Azores

This paper lists the noteworthy bryophytes collected by the authors in 1980 and 1992 on five of the nine islands of the Azores. Twenty-one species are new to the Azores three of these (Riccia beyrichiana, Dicranella schreberiana and Ephemerum cohaerens) being new to Macaronesia. Reasons are given for regarding Ptychomitrium azoricum as a synonym of P. polyphyllum and Tortella cirrifolia as a variety or subspecies of T. nitida.
