The Lycopodiaceae are an old family of vascular plants, including all of the core clubmosses and firmosses, comprising 16 accepted genera and about 400 known species. This family originated about 380 million years ago in the early Devonian, though the diversity within the family has been much more recent. "Wolf foot" is another common name for this family due to the resemblance of either the roots or branch tips to a wolf's paw.
Lycopodium is a genus of clubmosses, also known as ground pines or creeping cedars, in the family Lycopodiaceae. Two very different circumscriptions of the genus are in use. In the Pteridophyte Phylogeny Group classification of 2016, Lycopodium is one of nine genera in the subfamily Lycopodioideae, and has from nine to 15 species. In other classifications, the genus is equivalent to the whole of the subfamily, since it includes all of the other genera. More than 40 species are accepted.
Huperzia lucidula is a bright, evergreen, rhizomatous clubmoss of the genus Huperzia.
Lycopodium clavatum is the most widespread species in the genus Lycopodium in the clubmoss family.
Lycopodiella is a genus in the clubmoss family Lycopodiaceae. The genus members are commonly called bog clubmosses, describing their wetland habitat. The genus has a cosmopolitan distribution, with centers of diversity in the tropical New World and New Guinea. In the past, the genus was often incorporated within the related genus Lycopodium, but was segregated in 1964. In the Pteridophyte Phylogeny Group classification of 2016, Lycopodiella is placed in the subfamily Lycopodielloideae, along with three other genera. In this circumscription, the genus has about 15 species. Other sources use a wider circumscription, in which the genus is equivalent to the Lycopodielloideae of PPG I, in which case about 40 species and hybrids are accepted.
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 central stem up to 5 cm tall bearing a spore-producing cone at the apex, and was previously classified variously in the family Lycopodiaceae or in its own family the Phylloglossaceae, but recent genetic evidence demonstrates it is most closely related to the genus Huperzia and is a sister clade to the genus Phlegmariurus, which was formerly included in Huperzia.
Phlegmariurus phlegmaria, synonym Huperzia phlegmaria, commonly known as either coarse tassel fern or common tassel fern, is an epiphytic species native to rainforests in Madagascar, some islands in the Indian Ocean, Asia, Australasia and many Pacific Islands. Phlegmariurus phlegmaria is commonly found in moist forests and rainforests at high altitudes, in and amongst mosses and other epiphytes. Members of the order Lycopodiales are commonly referred to as clubmosses.
Lycopodiella inundata is a species of club moss known by the common names inundated club moss, marsh clubmoss and northern bog club moss. It has a circumpolar and circumboreal distribution, occurring throughout the northern Northern Hemisphere from the Arctic to montane temperate regions in Eurasia and North America. It grows in wet habitat, such as bogs, ponds, moist spots on the tundra, and long-standing borrow pits.
Dendrolycopodium dendroideum, synonym Lycopodium dendroideum, known as tree groundpine, is a North American species of clubmoss. It is part of a complex of species colloquially known as groundpine, which taxa were formerly lumped into the species Lycopodium obscurum. The species is native to Russia and also to the colder parts of North America. The genus Dendrolycopodium is accepted in the Pteridophyte Phylogeny Group classification of 2016, but not in other classifications, which submerge the genus in Lycopodium.
Diphasiastrum digitatum is known as groundcedar, running cedar or crowsfoot, along with other members of its genus, but the common name fan clubmoss can be used to refer to it specifically. It is the most common species of Diphasiastrum in North America. It is a type of plant known as a clubmoss, which is within one of the three main divisions of living vascular plants. It was formerly included in the superspecies Diphasiastrum complanatum. For many years, this species was known as Lycopodium flabelliforme or Lycopodium digitatum.
Palhinhaea cernua, synonym Lycopodiella cernua and Lycopodium cernuum, is a plant in the family Lycopodiaceae, commonly known as the staghorn clubmoss. The Hawaiian name for the plant is wāwaeʻiole, or "rat's foot". It has a substantial number of scientific synonyms in several genera. The genus Palhinhaea is accepted in the Pteridophyte Phylogeny Group classification of 2016, but not in other classifications which submerge the genus in Lycopodiella. It is the largest of the clubmosses, having rhizomes up to 5 m (16 ft) in length, with leafy uprights up to 2.5 m in height.
Diphasium scariosum, synonym Lycopodium scariosum, commonly known as spreading clubmoss or creeping club moss, is a species in the club moss family Lycopodiaceae. The genus Diphasium is accepted in the Pteridophyte Phylogeny Group classification of 2016, but not in other classifications which submerge the genus in Lycopodium. D. scariosum is native to Australia, New Zealand, and Borneo.
Diphasiastrum tristachyum, commonly known as blue clubmoss, blue ground-cedar, ground pine, deep-rooted running-pine or ground cedar, is a North American and Eurasian species of clubmoss. In North America, it has been found from Newfoundland west to Manitoba, and south as far as Georgia and Alabama. In Eurasia, it ranges from southern Norway and Sweden south to France and Italy and it also occurs in the Caucasus.
Dendrolycopodium hickeyi known as Hickey's tree club-moss or Pennsylvania clubmoss, is a North American species of clubmoss in the family Lycopodiaceae. It is native to eastern and Central Canada and the eastern and north-central United States. The genus Dendrolycopodium is accepted in the Pteridophyte Phylogeny Group classification of 2016, but not in other classifications, which submerge the genus in a larger Lycopodium.
Lateristachys diffusa, synonym Lycopodiella diffusa, known as carpet clubmoss, is a species of clubmoss in the family Lycopodiaceae. It is indigenous to New Zealand and to Tasmania, Australia.
Lycopodiella appressa, commonly known as southern bog clubmoss, is a species of clubmoss. It is native to eastern North America, including Cuba and the West Indies. In the United States, it is primarily found on the Coastal Plain.
Lycopodielloideae is a subfamily in the family Lycopodiaceae in the Pteridophyte Phylogeny Group classification of 2016. It is equivalent to a broad circumscription of the genus Lycopodiella in other classifications. Like all lycophytes, members of the Lycopodielloideae are vascular plants that reproduce by spores.
Pseudolycopodiella caroliniana, known as slender bog club-moss, is a species of lycophyte in the family Lycopodiaceae. The genus Pseudolycopodiella is accepted in the Flora of North America and the Pteridophyte Phylogeny Group classification of 2016, but not in other classifications, which submerge the genus in Lycopodiella. The species has a discontinuous distribution, being native to the eastern United States and to parts of eastern Asia.
Timmia megapolitana, also known as Indian feather moss and warrior moss is a genus of moss in the family Timmiaceae and order Timmiales.
