Editing Huperzia (section)

==Taxonomy==
The genus ''Huperzia'' was created by [[Johann Jakob Bernhardi]] in 1801. Bernhardi separated ''Huperzia'' from ''Lycopodium''. The [[type species]] is ''Lycopodium selago'' which became ''[[Huperzia selago]]''.<ref name=IPNI_30000333-2/>

In the [[Pteridophyte Phylogeny Group]] classification of 2016 (PPG I), ''Huperzia'' is placed in the subfamily [[Huperzioideae]] of the family [[Lycopodiaceae]].<ref name=PPGI/> A [[Phylogenetics|phylogenetic]] study in 2016, employing both molecular and morphological data, concluded that either a one-genus or a three-genus division of the subfamily produced [[Monophyly|monophyletic]] taxa. The authors preferred the three-genus division, recognizing ''Huperzia'', ''[[Phlegmariurus]]'' and ''[[Phylloglossum]]''. Their preferred hypothesis for the relationships of the three genera was:<ref name=FielTestBostHolt16/>

      |1=''[[Phylloglossum]]''
      |2=''Huperzia''
      }}
   |2=''[[Phlegmariurus]]''
   }}
}}
The majority of the species formerly placed in a broadly defined ''Huperzia'' belong in ''Phlegmariurus''.<ref name=FielTestBostHolt16/> Earlier, the ''Flora of North America'' had also separated ''Huperzia'' from ''Phegmariurus''.<ref name=FNA/> However, ''Phlegmariurus'' is difficult to separate morphologically, and others have preferred the one-genus division of the subfamily.<ref name=CFLW_Phl/><ref name=POWO_30000333-2/>

===Species===
The PPG I classification stated there were 25 species in the genus ''Huperzia''.<ref name=PPGI/> {{As of|2024|June}}, ''World Ferns'' listed the following species, noting that "many species still need transfer into other split genera".<ref name=CFLW_Hup/>
