Editing Lycophyte (section)

===Classification===
In the broadest [[Circumscription (taxonomy)|circumscription]] of the lycophytes, the group includes the extinct [[zosterophyll]]s as well as the extant (living) lycophytes and their closest extinct relatives. The names and ranks used for this group vary considerably. Some sources use the names "Lycopodiophyta" or the shorter "Lycophyta" to include zosterophylls as well as extant lycophytes and their closest extinct relatives,<ref name=Dowe17>{{Citation |mode=cs1 |last1=Doweld |first1=Alexander B. |date=2017 |title=(2499) Proposal to conserve the name Zosterophyllaceae against Sciadophytaceae (Fossil Lycopodiophyta: Zosterophyllopsida) |journal=Taxon |volume=66 |issue=1 |pages=207–208 |doi=10.12705/661.27 |doi-access=free }}</ref> while others use these names to exclude zosterophylls.<ref name=TaylTaylKrin09/><ref name=Maus14/> The name "Lycopodiophytina" has also been used in the inclusive sense.<ref name=KenrCran97a/><ref name=KenrCran97b/> English names, such as "lycophyte", "lycopodiophyte" or "lycopod", are similarly ambiguous, and may refer to the broadly defined group or only to the extant lycophytes and their closest extinct relatives.

The consensus classification produced by the [[Pteridophyte Phylogeny Group]] classification in 2016 (PPG&nbsp;I) places all extant (living) lycophytes in the class [[Lycopodiopsida]].<ref name=PPGI/> There are around 1,290 to 1,340 such species.<ref name=CallCook99/><ref name=ChriByng16/><ref name=PPGI/> For more information on the classification of extant lycophytes, see {{section link|Lycopodiopsida|Classification}}.
