Erzberger, Peter; Papp, Beáta: Annotated checklist of Hungarian bryophytes
Studia bot. hung. 35, pp. 91-149, 2004 ANNOTATED CHECKLIST OF HUNGARIAN BRYOPHYTES P. ERZBERGER 1 and B. PAPP 2 1 Beiziger Str. 37, D-10823 Berlin, Germany; E-mail: erzberger.peter@berlin.de 2 Department of Botany, Hungarian Natural History Museum H-1476 Budapest, Pf. 222, Hungary; E-mail: pappbea@bot.nhmus.hu The checklist presented below contains 629 bryophyte taxa in 199 genera, 2 species of horn worts in 2 genera, 141 species and 2 additional subspecies of liverworts in 50 genera and 483 species and 1 additional subspecies of mosses in 147 genera. It is the first inventory of Hungarian bryophytes in twenty years. Not all problems resulting from changes in taxonomy could be resolved yet, but the fields where further research is necessary are pointed out. Separate lists of excluded (46), doubtful (42) and recently added taxa (30) are provided. The annotations comment on taxonomic and nomenclatural changes, quote specimen details or contain otherwise relevant information. Key words: bryophytes, checklist, Hungary INTRODUCTION This is the first attempt to prepare an up-dated checklist of all bryophyte taxa of Hungary, more than twenty years after the publication of the "Handbook of the Hungarian Bryoflora" (ORBÁN and VAJDA 1983). Since then, partly as a result of fieldwork and partly resulting from herbarium revision, several new species have been added to the Hungarian bryoflora. Other taxa, some reported in ORBÁN and VAJDA (1983) and many in numerous other papers as occurring in Hungary, are now considered to be absent from Hungary, due to the application of better descriptions of taxa or to the amendment of various errors, especially with respect to geography. The species concerned are listed in the appendices. A considerable number of taxonomic and nomenclatural changes have accumulated within the last two decades, and thus the need to replace the somewhat out-of-date ORBÁN and VAJDA (1983) by a modern checklist has been increasingly felt. The application of national and international legislation with respect to the conservation of nature must be founded on an inventory of species that reflects the present state. This kind of inventory is also a prerequisite for the preparation of a red data book of bryophytes satisfying modern criteria (IUCN 1994). One of the most serious problems of an up-dated treatment of Hungarian bryophyte taxa lies in the difficulties of interpretation of old reports, in cases when the concepts of taxa have changed in the meantime. This concerns a considerable proportion of the Hungarian bryoflora. On the other hand, Hungarian bryology, fortunately, is in possession of a large body of herbarium specimens collected by Studia Botanica Hungarica 35, 2004 Hungarian Natural History Museum, Budapest
