'''''Huperzia''''' is a [[genus]] of [[Lycopodiopsida|lycophyte]] plants, sometimes known as the '''firmosses''' or '''fir clubmosses'''; the ''Flora of North America'' calls them '''gemma fir-mosses'''.<ref name=FNA/> This genus was originally included in the related genus ''[[Lycopodium]]'', from which it differs in having undifferentiated sporangial leaves, and the sporangia not formed into apical cones.  The common name ''firmoss'', used for some of the north temperate species, refers to their superficial resemblance to branches of [[fir]] (''Abies''), a [[conifer]]. {{As of|2020}}, two very different [[Circumscription (taxonomy)|circumscriptions]] of the genus were in use. In the [[Pteridophyte Phylogeny Group]] classification of 2016 (PPG I), ''Huperzia'' is one of three genera in the subfamily [[Huperzioideae]] of the family [[Lycopodiaceae]]. Most species in the subfamily are placed in the genus ''[[Phlegmariurus]]''. ''Huperzia'' is left with about 25 species,<ref name=PPGI/> although not all have been formally transferred to other genera.<ref name=CFLW_Hup/> Other sources recognize only ''Huperzia'', which then has about 340 species.<ref name=POWO_30000333-2/>
