I consider that there are only four species of this genus <lb xmlns="http://www.tei-c.org/ns/1.0" />two of which at least are very widely distributed: <name xmlns="http://www.tei-c.org/ns/1.0" type="plant"><hi rendition="#u"><choice> <abbr>Sph.</abbr> <expan>Sphagnum</expan> </choice></hi> <lb /><hi rendition="#u">latifolium</hi></name> occurs in <del xmlns="http://www.tei-c.org/ns/1.0" rendition="#s">all the</del> marshes <subst xmlns="http://www.tei-c.org/ns/1.0"> <del rendition="#s">of</del> <add place="superlinear">throughout all</add> </subst> <placeName xmlns="http://www.tei-c.org/ns/1.0" ref="https://edition-humboldt.de/H0005696 https://www.geonames.org/6255148">Europe</placeName>.
