Abstract

Fixed heterozygous banding patterns observed for 4 allozyme and 12 microsatellite loci, in combination with a chromosome number of 14, show that Polytrichum longisetum is an allodiploid species. Comparison of these banding patterns with those of related Polytrichaceae species suggest that Polytrichum formosum, or an ancestor taxon of this species, is one of the haploid progenitors of P. longisetum. The second progenitor species of P. longisetum could not be designated in this study as it was not among the examined possible progenitor species. DNA sequence data for two microsatellite loci, however, suggest that the second progenitor species should possibly be more closely related to P. formosum than any of the other haploid possible progenitor species examined in this study. As the current systematic literature does not mention the existence of such a species, this could indicate that the second progenitor species is already extinct.
