Firmosses
''Huperzia'' is a genus of lycophyte plants, sometimes known as the firmosses or fir clubmosses; the ''Flora of North America'' calls them gemma fir-mosses. 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. , two very different 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, although not all have been formally transferred to other genera. Other sources recognize only ''Huperzia'', which then has about 340 species. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huperzioideae
Huperzioideae is a subfamily of lycopsids in the family Lycopodiaceae. It has sometimes been recognized as a separate family, Huperziaceae. The Pteridophyte Phylogeny Group classification of 2016 (PPG I) recognizes three extant genera: *''Huperzia'' (temperate firmosses); about 25 species; terrestrial. *''Phlegmariurus'' (tropical firmosses); about 250 species; previously included in ''Huperzia''; mainly epiphytes. *''Phylloglossum ''Phylloglossum'', a genus in the clubmoss family Lycopodiaceae, is a small plant superficially resembling a tiny grass plant, growing with a rosette of slender leaves 2–5 cm long from an underground bulb-like root. It has a single centr ...'' (pygmy clubmoss); formerly thought to be only distantly related to ''Huperzia''. This is a terrestrial, grass-like plant with basal, 2–5 cm long, fleshy leaves. The only accepted species is '' Phylloglossum drummondii''. The plants are distinct from those of other members of the Lycopodiaceae ...
