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] |
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 ...

Lycopodielloideae
Lycopodielloideae 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 ''Lycopodiella'' in other classifications. Like all lycophytes, members of the Lycopodielloideae are vascular plants that reproduce by spores. Description The sporophytes of Lycopodielloideae 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 and upright. 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 from the normal leaves, and are grouped into compact terminal structures (strobili). The strobili may be either uprig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pteridophyte Phylogeny Group
The Pteridophyte Phylogeny Group, or PPG, is an informal international group of systematic botanists who collaborate to establish a consensus 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). 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 suborders, as well as families not placed in a suborder: Classification to subfamily level To the level of subfamily, the PPG I classification is as follows. *Class Lycopodi ...

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 placed the ...

Diphasiastrum
''Diphasiastrum'' is a genus of clubmosses in the plant family Lycopodiaceae. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it is placed in the subfamily Lycopodioideae. It is closely related to the genus ''Lycopodium'', and some botanists treat it within a broad view of that genus as a section, ''Lycopodium'' sect. ''Complanata''. Some species superficially resemble diminutive gymnosperms and have been given common names such as ground-pine or ground-cedar. There are 16 species, and numerous natural hybrids in the genus; many of the hybrids are fertile, allowing their occurrence to become frequent, sometimes more so than the parent species. The basal chromosome count for this genus is ''n=23'', which is distinctively different from other lycopods. Several species have been used economically for their spores, which are harvested as Lycopodium powder.
