Sphaerocarpos Muccilloi
''Sphaerocarpos muccilloi'' is a species of liverwort in the family Sphaerocarpaceae. Description ''Sphaerocarpos muccilloi'' grows in pale green mats. The thallus tissue is around five cells thick towards the center of the plant, but becomes as thin as one cell towards the edges. Those cells towards the edges are square or rectangular in shape, and are 56–108 micrometers (µm) long by 30–50 µm wide. The involucre which protects the plant's inflorescence is aggregate and oval- or cylindrical-shaped. It has a length of 1–2 millimeters (mm) and the opening is 170–280 µm wide.Vianna, 58. Dioecy ''S. muccilloi'' is a dioecious species, which means individual plants will have either male or female reproductive organs instead of both. The female plants grow roughly in a circular shape and are about 5–8 mm long. They are lobed, and the lobes grow upwards somewhat, with many rhizoids on their undersides. The male plants are more oval-shaped and also lobed. They are pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marchantiophyta
The Marchantiophyta () are a division of non-vascular land plants commonly referred to as hepatics or liverworts. Like mosses and hornworts, they have a gametophyte-dominant life cycle, in which cells of the plant carry only a single set of genetic information. It is estimated that there are about 9000 species of liverworts. Some of the more familiar species grow as a flattened leafless thallus, but most species are leafy with a form very much like a flattened moss. Leafy species can be distinguished from the apparently similar mosses on the basis of a number of features, including their single-celled rhizoids. Leafy liverworts also differ from most (but not all) mosses in that their leaves never have a costa (present in many mosses) and may bear marginal cilia (very rare in mosses). Other differences are not universal for all mosses and liverworts, but the occurrence of leaves arranged in three ranks, the presence of deep lobes or segmented leaves, or a lack of clearly ...

Hornwort
Hornworts are a group of non-vascular Embryophytes (land plants) constituting the division Anthocerotophyta (). The common name refers to the elongated horn-like structure, which is the sporophyte. As in mosses and liverworts, hornworts have a gametophyte-dominant life cycle, in which cells of the plant carry only a single set of genetic information; the flattened, green plant body of a hornwort is the gametophyte stage of the plant. Hornworts may be found worldwide, though they tend to grow only in places that are damp or humid. Some species grow in large numbers as tiny weeds in the soil of gardens and cultivated fields. Large tropical and sub-tropical species of '' Dendroceros'' may be found growing on the bark of trees. The total number of species is still uncertain. While there are more than 300 published species names, the actual number could be as low as 100-150 species. Description Like all bryophytes, the dominant life phase of a hornwort is the haploid gametophyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petrified Wood
Petrified wood, also known as petrified tree (from Ancient Greek meaning 'rock' or 'stone'; literally 'wood turned into stone'), is the name given to a special type of '' fossilized wood'', the fossilized remains of terrestrial vegetation. '' Petrifaction'' is the result of a tree or tree-like plants having been replaced by stone via a mineralization process that often includes permineralization and replacement. The organic materials making up cell walls have been replicated with minerals (mostly silica in the form of opal, chalcedony, or quartz). In some instances, the original structure of the stem tissue may be partially retained. Unlike other plant fossils, which are typically impressions or compressions, petrified wood is a three-dimensional representation of the original organic material. The petrifaction process occurs underground, when wood becomes buried in water-saturated sediment or volcanic ash. The presence of water reduces the availability of oxygen which inhi ...

Santana Do Livramento
Santana do Livramento is a city in the state of Rio Grande do Sul, Brazil. It is located along the border with the city of Rivera, Uruguay, forming together an international city of almost 170,000 inhabitants. Santana do Livramento was founded on July 30, 1823, and in 1857 was emancipated from Alegrete as a city. In 2009, the city was officially declared by the Brazilian government as the symbolic city of Brazilian integration with the Mercosur member states. History The first known occupants of the region of the current municipality were the Charrúa and minuane indigenous. Then came Spanish Jesuits, then throughout the 19th century came Portuguese and Italian immigrants. In 1810, the political instability that would lead to the independence of the Spanish colonies in the Platina Basin led to the arrival of Portuguese troops to the region, in order take advantage of the opportunity and extend their empire in areas of temperate weather so coveted by them. These troops, com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleobotanical Sites Of Arenito Mata
Paleobotany, which is also spelled as palaeobotany, is the branch of botany dealing with the recovery and identification of plant remains from geological contexts, and their use for the biological reconstruction of past environments (paleogeography), and the evolutionary history of plants, with a bearing upon the evolution of life in general. A synonym is paleophytology. It is a component of paleontology and paleobiology. The prefix ''palaeo-'' means "ancient, old", and is derived from the Greek adjective , . Paleobotany includes the study of terrestrial plant fossils, as well as the study of prehistoric marine photoautotrophs, such as photosynthetic algae, seaweeds or kelp. A closely related field is palynology, which is the study of fossilized and extant spores and pollen. Paleobotany is important in the reconstruction of ancient ecological systems and climate, known as paleoecology and paleoclimatology respectively; and is fundamental to the study of green ...

Ivoti
Ivoti is a municipality in the Brazilian state of Rio Grande do Sul, located in the Porto Alegre metropolitan area. The population is 24,690 (2020 est.) in an area of 63.15 km². History Originally occupied by indigenous people since 12,000 years ago (known as the ''Umbu Tradition''), the area started to be explored by bandeirantes in the 18th Century and later was used as a rout to transport cattle.

Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almos ...
