“…Gametophytes with 19 chromosomes are considered to be haploid, whereas those with 38 chromosomes are considered to be diploid (and thus polyploid). Bryan (1955) determined that gametophytes of S. perichaetiale (as S. erthyocalyx hampe) from North Carolina had 19 chromosomes. The present data suggest that this species also has haploid gametophytes in New Zealand, based on the observation that all of 16 microsatellite loci exhibit a single allele.…”

“…Three other section Sphagnum species are reported to be polyploids: S centrale, S. palustre, and S.papillosum (Bryan 1955;holmen 1955;Maass & harvey 1973;Fritsch 1991;Temschetal. 1998), and preliminary data for S. palustre shows that it has a pattern of microsatellite alleles similar to that of S. cristatum (E.

The systematics of Sphagnum section Sphagnum in New Zealand has been controversial. Two species are currently recognised in the New Zealand flora, S. cristatum and S. perichaetiale, but the presence of the widespread S. magellanicum has been debated. An analysis of 16 microsatellite loci shows that the gametophytes of Sphagnum perichaetiale appear to have one monoploid set of chromosomes (i.e., are haploid). Fixed heterozygosity at 10 loci indicates that S. cristatum is an alloploid. A red morphotype of S. cristatum, similar in macroappearance to S. magellanicum, is not genetically differentiated from the more common brown-green morphotypes of S. cristatum. Although analysis of the microsatellite data for S. cristatum showed most of the genetic variation to be within populations, significant variation did occur among populations within regions and also between regions.

“…Lowry, who first applied cytological data to systematics problems, worked on Mnium (1918) and Atrichum (1954). Other eytotaxonomie investigations have been made on Sphagnum (BRYAN, 1955(BRYAN, , 1966I-IoLMF, N, 1955); Fissidens (ANDERSON and B~YAN, 1956); Pleuridium and Bruchia (Bt~YAI~, 1956b); Ditrichum (B~YAN, 1956 b;A~D~SON and BRYAn, 1958 b) ; Astomum, Acaulon and Phascum (B~,TAx, 1956 a) ; Ephemerum, Nanomitrium, Aphanorhegma, and Physcomitrella (B~YAN, 1957;BRYAN and AxD]~SON, 1957); Atrichum (C~o~A and B~A~DA~I, 1959), Dicranum (BI~IGGS, 1965); Polytrichum formosum (OsADA and YA~o, 1966); Tortula murales (NEwTOn, 1968); and Mnium (BowERs, 1969 a).…”

“…The chromosome claimed as m (h) by the Japanese workers is approximately one-third to one-fourth the size of the largest chromosome. This chromosome, therefore, cannot be accepted as being truly of the m type, which is dimunitive (Steere, 1954;Bryan, 1955;Ramsay, 1964) and only one-tenth the size of the largest chromosome (Wylie, 1957). Anderson and Bryan (1958) and Al-Aish and Anderson (1960c) speculated that the m (h) chromosome may not be observable in the somatic complement of the Japanese Thuidia.…”
