Bucegia romanica Radian (Marchantiaceae) is reported for the first time from
Svalbard significantly extending the previously known range. The level of
ITS1-2 nrDNA, trnL-F
and trnG-intron cpDNA
nucleotide sequence variability from European and Svalbard populations is quite
low and any significant morphological differences between specimens are not
revealed. Characters differentiating Bucegia
romanica from similar the at first glance Preissia quadrata (Scop.) Nees and Asterella lindenbergiana (Corda ex Nees) Arnell as well as ecology
of the species in Svalbard and worldwide are discussed. The global
distribution of the species is reviewed and mapped.
