Aztekium
The genus ''Aztekium'' contains three species of small globular cactus. Discovered in 1929 by F. Ritter, in Rayones, Nuevo León, Mexico, this genus was thought to be monotypic (with ''Aztekium ritteri'') until a second species ('' Aztekium hintonii'') was discovered by George S. Hinton, in Galeana, Nuevo León in 1991. A further possible species, ''Aztekium valdezii'', was described in 2011, but is considered to be a synonym of ''A. ritteri''. Description ''Aztekium ritteri'' is a small plant (around 20 mm wide), with 9 to 11 ribs, which typically have transverse wrinkles. Its color varies from pale green to grayish-green. The center of the cactus contains a lot of white wool. Flowers are small (less than 10 mm wide), with white petals and pinkish sepals. The plants bear small pinkish berry-like fruits. ''A. hintonii'' is larger, to 10 cm in diameter, 10 to 18 grooved ribs, flowers magenta to 3 cm. It grows only on gypsum. Species Etymology Its name ...

Aztekium Ritteri
''Aztekium ritteri'' is a species of cactus, in the genus ''Aztekium''. It is one of the three species that make up the genus. The species originated in Mexico. Aztekium is a genus endemic to Mexico.

Nuevo León
Nuevo León () is a state in the northeast region of Mexico. The state was named after the New Kingdom of León, an administrative territory from the Viceroyalty of New Spain, itself was named after the historic Spanish Kingdom of León. With a total land area of 64,555 square kilometers (40,112 square miles), Nuevo León is the 13th largest federal entity in Mexico. The state is bordered by Tamaulipas to the east, Coahuila to the west, and both Zacatecas and San Luis Potosi to the south. To the north, it shares an international border with the U.S. state of Texas. The Laredo-Colombia Solidarity International Bridge is the only vehicular bridge that connects the United States with the state of Nuevo León. It crosses over the Rio Grande (Rio Bravo) between the city of Colombia, Nuevo León, and Laredo, Texas.

Cactoideae Genera
The Cactoideae are the largest subfamily of the cactus family, Cactaceae. Around 80% of cactus species belong to this subfamily. , the internal classification of the family Cactaceae remained uncertain and subject to change. A classification incorporating many of the insights from the molecular studies was produced by Nyffeler and Eggli in 2010. Various revisions have been published since, e.g. to the tribe Hylocereeae and the tribe Echinocereeae. Classifications remained uncertain . Tribes and genera , the National Center for Biotechnology Information used the division of the subfamily into tribes shown below. Some revisions to the circumscriptions of the tribes are also shown. * Blossfeldieae **''Blossfeldia'' *Browningieae **''Armatocereus'' – ''Browningia'' – '' Neoraimondia'' – '' Stetsonia'' *Cacteae **''Acharagma'' – ''Ariocarpus'' – '' Astrophytum'' – ''Aztekium'' – '' Coryphantha'' – '' Cumarinia'' – ''Ech ...

Cactus
A cactus (, or less commonly, cactus) is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. Although some species live in quite humid environments, most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spines, ...

N-methyltyramine
''N''-Methyltyramine (NMT), also known as 4-hydroxy-''N''-methylphenethylamine, is a human trace amine and natural substituted phenethylamine, phenethylamine alkaloid found in a variety of plants.T. A. Smith (1977). "Phenethylamine and related compounds in plants." ''Phytochemistry'' 16 9 – 18. As the name implies, it is the N-methyl analog of tyramine, which is a well-known biogenic amine, biogenic trace amine with which NMT shares many pharmacological properties. Biosynthetically, NMT is produced by the N-methylation of tyramine via the action of the enzyme phenylethanolamine N-methyltransferase, phenylethanolamine ''N''-methyltransferase in humans and tyramine N-methyltransferase, tyramine ''N''-methyltransferase in plants. Occurrence N-methyltyramine seems to be quite widely distributed in plants. NMT was isolated as a natural product for the first time, from germinating barley roots, by Kirkwood and Marion in 1950. These chemists found that 600 g of barley, after germinat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medicinal Plants Of North America
Medicine is the science and practice of caring for a patient, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others. Medicine has been practiced since prehistoric times, and for most of this time it was an art (an area of skill and knowledge), frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for healing, or an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Nuevo León
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of Mexico
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
