Acutifolia ( Sphagnaceae, Bryophyta ) [Elektronische Daten] [Nils Cronberg] Ten enzyme systems coding for 13 putative loci were studied in 12 European species ofSphagnum sect.Acutifolia (peat mosses). On average seven plants from each of 73 collections made throughout N Europe were analysed. Despite complex morphological variation, all species expressed unique allele combinations. Principal components and cluster analyses based on allele frequencies showed that sect.Acutifolia can be divided into two major groups; one comprisingSphagnum fimbriatum, S. girgensohnii andS. molle; the second comprisingS. capillifolium, S. angermanicum, S. fuscum, S. quinquefarium, S. rubellum, S. subfulvum, S. subnitens andS. warnstorfii. These groups are linked byS. russowii, which is shown to be an allopolyploid, with fixed heterozygosity at 6 to 8 of the loci. The presumed progenitors ofS. russowii areS. girgensohnii andS. rubellum. Allelic data also indicate thatS. teres from sect.Squarrosa is related toS. girgensohnii andS. fimbriatum. The bisexual species tend to be less variable than the unisexual species.
