Lycopodiaceae (homosporous lycophytes) split off from the branch leading to Selaginella and Isoetes (heterosporous lycophytes) about ~400 million years ago, during the early Devonian. The two subfamilies Lycopodioideae and Huperzioideae diverged ~350 million years ago, but has evolved so slowly that about 30% of their genes are still in ...
Lycopodioideae is a subfamily in the family Lycopodiaceae in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). [1] It is equivalent to a broad circumscription of the genus Lycopodium in other classifications. Like all lycophytes, members of the Lycopodioideae reproduce by spores.
Lycopodiopsida is a class of vascular plants also known as lycopsids, [1] lycopods, or lycophytes.Members of the class are also called clubmosses, firmosses, spikemosses and quillworts.
Lycopodium (from Ancient Greek lykos, wolf and podion, diminutive of pous, foot) [2] is a genus of clubmosses, also known as ground pines or creeping cedars, [3] in the family Lycopodiaceae. Two very different circumscriptions of the genus are in use.
Palhinhaea cernua, synonym Lycopodiella cernua and Lycopodium cernuum, is a plant in the family Lycopodiaceae, [2] commonly known as the staghorn clubmoss. [3] The Hawaiian name for the plant is wāwaeʻiole, or "rat's foot". It has a substantial number of scientific synonyms in several genera.
Huperzia selago, the northern firmoss or fir clubmoss, is a vascular plant in the family Lycopodiaceae. [2] It is small-ish, sturdy, stiff and upright and densely scale-leaved. This plant is an evergreen, perennial pteridophyte. The spores are produced June to September. [3] It has a circumpolar distribution. [4]
Spinulum annotinum, synonym Lycopodium annotinum, known as interrupted club-moss, [1] or stiff clubmoss, [2] is a species of clubmoss native to forests of the colder parts of North America (Greenland, St. Pierre & Miquelon, all 10 provinces and all 3 territories of Canada, Alaska, and mountains of the contiguous United States), [3] as well as Asia (China, Russia, Japan, Korea, Nepal, Assam ...
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: [1] Huperzia (temperate firmosses); about 25 species; terrestrial.
