Lycopodium
''Lycopodium'' (from 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 leaves contain a single, unbranched vascular strand, and are microphylls by definition. The kidney-shaped (reniform) spore-cases (sporangia) contain spores of one kind only, ( i ...

Austrolycopodium Fastigiatum
''Austrolycopodium fastigiatum'', synonym ''Lycopodium fastigiatum'', commonly known as alpine club moss or mountain club moss, is a species of club moss native to New Zealand and Australia. The genus ''Austrolycopodium'' is accepted in the Pteridophyte Phylogeny Group classification of 2016 (PPG I), but not in other classifications which submerge the genus in ''Lycopodium''. ''Austrolycopodium fastigiatum'' has an upright, much branched and conifer-like appearance, and can grow up to high. It is widespread across New Zealand including Stewart, Chatham, Adams, Auckland, and Campbell Islands.

Austrolycopodium Magellanicum
''Austrolycopodium magellanicum'', Synonym (taxonomy), synonym ''Lycopodium magellanicum'', the Magellanic clubmoss, is a species of vascular plant in the club moss family Lycopodiaceae. The genus ''Austrolycopodium'' is accepted in the Pteridophyte Phylogeny Group classification of 2016 (PPG I), but not in other classifications which submerge the genus in ''Lycopodium''. The species grows in the mountains of Latin America from Costa Rica and the Dominican Republic south as far as Tierra del Fuego, as well as a number of islands in the antarctic and subantarctic oceans (Tristan da Cunha, Gough Island, Amsterdam Island, South Georgia and the South Sandwich Islands, Falkland Islands, Juan Fernández Islands, Marion Island, Prince Edward Islands, Iles Crozet, Iles Kerguelen). A number of natural products have been isolated from this plant, including magellanine, magellaninone, panticuline, acetyldihydrolycopodine, acetylfawcettiine, clavolonine (8b-hydroxylycopodine), deacetylfawce ...

Lycopodioideae
''Lycopodioideae'' is a subfamily in the family Lycopodiaceae in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). It is equivalent to a broad circumscription of the genus ''Lycopodium'' in other classifications. Like all lycophytes, members of the Lycopodioideae reproduce by spores. The oldest fossils of modern members of the family date to the Early Cretaceous. Description The sporophytes of Lycopodioideae species are relatively short herbaceous plants. They have stems with pseudomonopodial branching in which unequal binary branching produces the appearance of a main stem with secondary side branches. The main stems are indeterminate and of various forms, including rhizomatous, creeping, trailing and climbing. They usually form roots at intervals along their length. The branches are usually determinate (i.e. of limited growth and extension). Sporangia are borne at the bases or in the axils of special spore-bearing leaves (sporophylls), which are notably different ...

Lycopodiaceae
The Lycopodiaceae (class Lycopodiopsida, order Lycopodiales) 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. 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 microphyll, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Josef Ludwig Holub
The Professor Josef Ludwig Holub (5 February 1930 in Mladá Boleslav, (now Czech Republic) – 23 July 1999) was a Czech botanist who described a number of new species, worked on systematic reorganization of botanical groups, and contributed greatly to the study of European flora. Biography Josef Holub studied at Charles University in Prague, becoming a lecturer in botany in 1953. He co-founded the Czech Institute of Botany where he worked for many years. He also helped create the Department of Biosystematics, and the journal ''Folia'', published by the "Geobotanical and Phytotaxonomic Institute. In 1991 he was named president of the Czech Botanical Society. He participated in many botanical field studies in central Europe. Work He worked on vascular plant taxonomy. He contributed to economic botany, especially with his work on the flora of Slovakia and the Czech Republic. *Holub, J et al. 1967.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
