Conocephalum Conicum
''Conocephalum conicum'', also known as the great scented liverwort or snakeskin liverwort, is a liverwort species in the genus ''Conocephalum''. ''C. conicum'' is part of the ''Conocephalum conicum'' complex, which includes several cryptic species. The name ''C. conicum'' refers to the cone-shaped archegoniaphore, which bear sporangia. Habitat and distribution ''C. conicum'' is one of the most common liverworts in northern hemisphere and is widely distributed throughout Canada. ''C. conicum'' is found in open woodlands, sandy banks, wet rocks or cliffs and moist soils and is strongly associated with calcareous substrates. Morphology Thalli ''C. conicum'' is the largest of the thalloid liverworts, growing up to 20 cm long. The thalli can grow to 17 mm wide. The thalli are very strong-smelling, with purplish margins; a dark green, leathery surface; flat and smooth. There is a set of lines running along the thalli's surface. The air pores, which are found between t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barthélemy Charles Joseph Dumortier
Barthélemy Charles Joseph Dumortier (; 3 April 1797 in Tournai – 9 July 1878) was a Belgian who conducted a parallel career of botanist and Member of Parliament. Biography Barthélemy Dumortier was a son of the merchant and city councillor Barthélemy-François Dumortier and of Mariue-Jeanne Willaumez. He married Philippine Ruteau and they had a son, Barthélemy-Noël Dumortier (1830-1915). Barthélemy-Charles became politically active in the early eighteen twenties. In 1824 he founded the ''Courrier de l'Escaut'', a paper critical of the government. He adhered in 1830 to the Belgian revolution. In 1831 he became a member of the first elected parliament of the new kingdom, as the member for Tournai. He remained elected until 1847. He then switched seats, and was now elected for the city of Roulers and held this seat until his death. In 1872 he was awarded the honorary title of Minister of State. He also was awarded nobility with the title of earl. However, for unknown reason ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptic Species
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thalli
Thallus (plural: thalli), from Latinized Greek (), meaning "a green shoot" or "twig", is the vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria. Many of these organisms were previously known as the thallophytes, a polyphyletic group of distantly related organisms. An organism or structure resembling a thallus is called thalloid, thallodal, thalliform, thalline, or thallose. A thallus usually names the entire body of a multicellular non-moving organism in which there is no organization of the tissues into organs. Even though thalli do not have organized and distinct parts (leaves, roots, and stems) as do the vascular plants, they may have analogous structures that resemble their vascular "equivalents". The analogous structures have similar function or macroscopic structure, but different microscopic structure; for example, no thallus has vascular tissue. In exceptional cases such as the Lemnoideae, where t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungus
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycelium
Mycelium (plural mycelia) is a root-like structure of a fungus consisting of a mass of branching, thread-like hyphae. Fungal colonies composed of mycelium are found in and on soil and many other substrate (biology), substrates. A typical single spore germinates into a Monokaryon, monokaryotic mycelium, which cannot reproduce sexually; when two compatible monokaryotic mycelia join and form a dikaryotic mycelium, that mycelium may form sporocarp (fungi), fruiting bodies such as mushrooms. A mycelium may be minute, forming a colony that is too small to see, or may grow to span thousands of acres as in ''Armillaria''. Through the mycelium, a fungus absorbs nutrients from its environment. It does this in a two-stage process. First, the hyphae secrete enzymes onto or into the food source, which break down biopolymers, biological polymers into smaller units such as monomers. These monomers are then absorbed into the mycelium by facilitated diffusion and active transport. Mycelia are v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marchantiales
Marchantiales is an order of thallose liverworts (also known as "complex thalloid liverworts") that includes species like ''Marchantia polymorpha'', a widespread plant often found beside rivers, and '' Lunularia cruciata'', a common and often troublesome weed in moist, temperate gardens and greenhouses. As in other bryophytes, the gametophyte generation is dominant, with the sporophyte existing as a short-lived part of the life cycle, dependent upon the gametophyte. The genus ''Marchantia'' is often used to typify the order, although there are also many species of ''Asterella'' and species of the genus ''Riccia'' are more numerous. The majority of genera are characterized by the presence of (a) special stalked vertical branches called archegoniophores or carpocephala, and (b) sterile cells celled elaters inside the sporangium. Phylogeny (extant Marchantiales) Based on the work by Villarreal et al. 2015 Phylogeny (extant and extinct Marchantiales) Extinct complex thalloid ...
