Two interesting bryofloristic records from the Krkonoše Mts - Racomitrium macounii subsp. alpinum and Grimmia reflexidens

During the field inventory survey of bryophytes in eastern part of the Krkonoše Mts carried out in 1998, a new species to the bryoflora of the Czech Republic was discovered - Racomitrium macounii subsp. alpinum. After the revision of Racomitrium sudeticum from herbaria PRC and PR, three other specimens of R. macounii subsp. alpinum were revealed, all of them collected in the vicinity of existing localities. Another interesting species discovered was Grimmia reflexidens (known to-date rather as Grimmia sessitana). This taxon was omitted from the recent check-list of Czech bryophytes (Váňa 1997) due to the doubts about Vilhelm's records and poor understanding of G. reflexidens with respect to Grimmia alpestris. The revision of Grimmia alpestris specimens from herbaria PRC, PR, BRNU and OP confirmed the Vilhelm's determination of G. reflexidens from the Krkonoše Mts as correct and excluded (for the time being) G. alpestris from bryoflora of these mountains. On the contrary, only G. alpestris could be confirmed for the bryoflora of the other high Sudeten Mts, i.e. the Hrubý Jeseník Mts.
