Editing Ophioglossum (section)

==Taxonomy==
''Ophioglossum'' has a high [[list of organisms by chromosome count|chromosome count in comparison to other species]], with 120 or up to 720 chromosomes possible in intervals of 120 due to polyploidy (multiple possible copies of chromosomes). It has almost 1260 number of chromosomes in the meiocyte (spore mother cell) which undergo meiosis, the reduction division to form the spore with only one set of chromosomes getting incorporated into each spore.<ref>{{Cite journal |last=Lukhtanov |first=Vladimir |date=2015-07-10 |title=The blue butterfly Polyommatus (Plebicula) atlanticus (Lepidoptera, Lycaenidae) holds the record of the highest number of chromosomes in the non-polyploid eukaryotic organisms |journal=Comparative Cytogenetics |language=en |volume=9 |issue=4 |pages=683–690 |doi=10.3897/compcytogen.v9i4.5760 |pmc=4698580 |pmid=26753083 |doi-access=free |bibcode=2015ComCy...9..683L }}</ref> The species ''[[Ophioglossum reticulatum]]'' has the highest number of chromosomes found in any multicellular organism.<ref>[https://bmcplantbiol.biomedcentral.com/articles/10.1186/1471-2229-13-219 Genome size expansion and the relationship between nuclear DNA content and spore size in the Asplenium monanthes fern complex (Aspleniaceae)]</ref>
