Lycopodiales
The Lycopodiaceae (class Lycopodiopsida, order Lycopodiales) are an old family of vascular plants, including all of the core clubmosses and firmosses, comprising 17 accepted genera and about 500 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. Description Members of Lycopodiaceae are not spermatophytes and so do not produce seeds. Instead they produce spores, which are oily and flammable, and are the most economically important aspects of these plants. The spores are of one size (i.e. the plants are isosporous) and are borne on a specialized structure at the apex of a shoot called a strobilus (plural: strobili), which resembles a tiny battle club, from which the common name derives. Members of the family share the common feature of having a microphy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lycopodiopsida
Lycopodiopsida is a class of vascular plants also known as lycopsids, lycopods, or lycophytes. Members of the class are also called clubmosses, firmosses, spikemosses and quillworts. They have dichotomously branching stems bearing simple leaves called microphylls and reproduce by means of spores borne in sporangia on the sides of the stems at the bases of the leaves. Although living species are small, during the Carboniferous, extinct tree-like forms ( Lepidodendrales) formed huge forests that dominated the landscape and contributed to coal deposits. The nomenclature and classification of plants with microphylls varies substantially among authors. A consensus classification for extant (living) species was produced in 2016 by the Pteridophyte Phylogeny Group (PPG I), which places them all in the class Lycopodiopsida, which includes the classes Isoetopsida and Selaginellopsida used in other systems. (See Table 2.) Alternative classification systems have used ranks from di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pteridophyte Phylogeny Group
The Pteridophyte Phylogeny Group (PPG) is an informal international group of systematic botanists who collaborate to establish on the classification of pteridophytes ( lycophytes and ferns) that reflects knowledge about plant relationships discovered through phylogenetic studies. In 2016, the group published a classification for extant pteridophytes, termed "PPG I". The paper had 94 authors (26 principal and 68 additional). The classification was presented as a consensus classification supported by the community of fern taxonomists. Alternative classifications of ferns exist and are preferred by some. PPG I A first classification, PPG I, was produced in 2016, covering only extant (living) pteridophytes. The classification was rank-based, using the ranks of class, subclass, order, suborder, family, subfamily and genus. Phylogeny The classification was based on a consensus phylogeny, shown below to the level of order. The very large order Polypodiales was divided into two subord ...

Lycopodiella
''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 (PPG I), ''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. Description ''Lycopodiella'' are non-flowering plants. They have leafy rhizomes that grow along the ground and vertical, leafy shoots, also known as peduncles. Fertile peduncles have strobili at the top of the shoot. Individu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spinulum Annotinum
''Spinulum annotinum'', synonym ''Lycopodium annotinum'', known as interrupted club-moss, or stiff clubmoss, 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), as well as Asia (China, Russia, Japan, Korea, Nepal, Assam), and most of Europe. It is an evergreen perennial pteridophyte. The genus '' Spinulum'' is accepted in the Pteridophyte Phylogeny Group classification of 2016 (PPG I), but not in other classifications, which submerge the genus in ''Lycopodium''. Description ''Spinulum annotinum'' is a common and widespread club-moss spreading by means of horizontal stems running along the surface of the ground. It is usually unbranched or sparingly branched, each branch containing a cone at the top. Leaves have minute teeth on their edges. The branches are long, upright and somewhat branchless themselves. The s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phlegmariurus
''Phlegmariurus'' is a genus of lycophyte plants in the family Lycopodiaceae. The genus is recognized in the Pteridophyte Phylogeny Group classification of 2016 (PPG I), but not by some other sources, which keep it in a broadly defined ''Huperzia''. Taxonomy The genus was first described in 1909 by Wilhelm Herter as the section ''Phlegmariurus'' of the genus ''Lycopodium''. The section was elevated to a genus by Josef Ludwig Holub in 1964. Within the family Lycopodiaceae, ''Phlegmariurus'' is placed in the subfamily Huperzioideae. A 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 monophyletic taxa. The authors preferred the three-genus division, recognizing ''Huperzia'', ''Phlegmariurus'' and ''Phylloglossum ''Phylloglossum'', a genus in the clubmoss Family (biology), family Lycopodiaceae, is a small plant superficially resembling a tiny Poaceae, grass plant, gr ...

Pseudolycopodium
''Pseudolycopodium'' is a genus of lycophyte in the family Lycopodiaceae with only one species, ''Pseudolycopodium densum'', known as the bushy clubmoss. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the genus is placed in the subfamily Lycopodioideae. Some sources do not recognize the genus, sinking it into '' Lycopodium''. ''Pseudolycopodium densum'' is native to Australia, the North Island of New Zealand and New Caledonia. It is a spore-bearing vascular plant and grows up to a metre high. It is found in a wide variety of situations, often in high rainfall areas on sandy soils. Taxonomy The species was first described in 1807 by Jacques Labillardière, as ''Lycopodium densum''. However, the name had already been used for a different species, so this name is illegitimate. Hence when Werner Rothmaler in 1944 placed the species in the genus ''Lepidotis'' as ''Lepidotis densa'', this was the first legitimate use of the epithet. In 1983, Josef Holub pla ...

Lycopodium
''Lycopodium'' (from Ancient Greek ''lykos'', wolf and ''podion'', diminutive of ''pous'', foot) 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 (PPG I), ''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. Description They are flowerless, vascular, terrestrial or epiphytic plants, with widely branched, erect, prostrate, or creeping stems, with small, simple, needle-like or scale-like leaves that cover the stem and branches thickly. The stems usually creep along the ground, forking at intervals. The leaves contain a single, unbranched vascular strand, and are microphylls by definition. They are usually ...
