Psychotria Viridis
''Psychotria viridis'', also known as ''chacruna'', ''chacrona'', or ''chaqruy'' in the Quechua languages, is a perennial, shrubby flowering plant in the coffee family Rubiaceae. It is a close relative of ''Psychotria carthagenensis'' (a.k.a. ''samiruka'' or ''amiruca'') of Ecuador. It is commonly used as an ingredient of ayahuasca, a decoction with a long history of its entheogenic (connecting to spirit) use and its status as a "plant teacher" among the Indigenous peoples of the Amazon rainforest. Description ''P. viridis'' is a perennial shrub that grows to a height of approximately . Its branches span a diameter of about Stems In the middle and lower parts of the stem, situated between the insertion points of the two opposite leaves there is a horizontal scar wide that extends between the leaves (or leaf scars) and sometimes also connects over the tops of these scars, and along the top side of this scar there is a dense, usually furry line of fine trichomes (i.e., plant ha ...

Hipólito Ruiz López
Hipólito Ruiz López (August 8, 1754 in Belorado, Burgos, Spain – 1816 in Madrid), or Hipólito Ruiz, was a Spanish botanist known for researching the floras of Peru and Chile during an expedition under Charles III of Spain, Carlos III from 1777 to 1788. During the reign of Carlos III, three major botanical expeditions were sent to the New World; Ruiz and José Antonio Pavón Jiménez were the botanists for the first of these expeditions, to Peru and Chile. Background After studying Latin with an uncle who was a priest, at the age of 14 Ruiz López went to Madrid to study logic, physics, chemistry and pharmacology. He also studied botany at the Migas Calientes Botanical Gardens (now the Real Jardín Botánico de Madrid), under the supervision of Casimiro Gómez Ortega (1741–1818) and Antonio Palau Verdera (1734–1793). Ruiz had not yet completed his pharmacology studies when he was named the head botanist of the expedition. The French physician Joseph Dombey was named as ...

Psychotria Viridis Leaves
''Psychotria'' is a large genus of flowering plants in the coffee family Rubiaceae, with over 1,600 species. The genus has a pantropical distribution and members of the genus are small understorey trees in tropical forests. Some species are endangered or facing extinction due to deforestation, especially species of central Africa and the Pacific. Many species, including ''Psychotria viridis'', produce the psychedelic chemical dimethyltryptamine (DMT).

N-Methyltryptamine
''N''-Methyltryptamine (NMT), also known as monomethyltryptamine, is a chemical compound of the tryptamine family and a naturally occurring compound found in the human body and certain plants. It is biosynthesized in humans from tryptamine by certain ''N''-methyltransferase enzymes, such as indolethylamine ''N''-methyltransferase. It is a known component in human urine. NMT is an alkaloid derived from L-tryptophan that has been found in the bark, shoots and leaves of several plant genera, including '' Virola'', ''Acacia'', '' Mimosa'', and '' Desmanthus''—often together with the related compounds ''N'',''N''-dimethyltryptamine (DMT) and 5-methoxy-''N'',''N''-dimethyltryptamine (5-MeO-DMT). NMT acts as a serotonin receptor agonist and serotonin releasing agent and is said to produce hallucinogenic effects in humans. Effects Orally administered NMT appears to produce no psychoactive effects, likely as a result of extensive first-pass metabolism. Per Roger W. Brimbl ...

Dimethyltryptamine
Dimethyltryptamine (DMT), also known as ''N'',''N''-dimethyltryptamine (''N'',''N''-DMT), is a Psychedelic drug, serotonergic hallucinogen and Investigational New Drug, investigational drug of the substituted tryptamine, tryptamine family that natural product, occurs naturally in many plants and animals, including humans. DMT is used as a psychedelic drug and prepared by various cultures for ritual purposes as an entheogen. DMT has a rapid onset of action, onset, intense effects, and a relatively short duration of action. For those reasons, DMT was known as the "businessman's trip" during the 1960s in the United States, as a user could access the full depth of a psychedelic experience in considerably less time than with other substances such as Lysergic acid diethylamide, LSD or psilocybin mushrooms. DMT can be inhaled or injected and its effects depend on the dose, as well as the mode of administration. When inhaled or injected, the effects last about five to fifteen minutes ...

Cutting (plant)
A plant cutting is a piece of a plant that is used in horticulture for vegetative reproduction, vegetative (asexual) plant propagation, propagation. A piece of the Plant stem, stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the Mother plant, parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems. Some plants can be grown from leaf pieces, called leaf cuttings, which produce both stems and roots. The scions used in grafting are also called cuttings. Propagating plants from cuttings is an ancient form of cloning. There are several advantages of cuttings, mainly that the produced offspring are practically clones of their parent plants. If a plant has favorable traits, it can continue to pass down its advantageous genetic information to its offspring. This is especially economically advantageous as i ...

Hardiness Zone
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by long-term average annual extreme minimum temperatures. It has been adapted by and to other countries (such as Canada) in various forms. A plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of . Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale. However, some confusion can exist in discussing buildings and HVAC, where "climate zone" can refer to the International Energy Conservation Code zones, where Zone 1 is warm and Zone 8 is cold. Other hardiness rating schemes have been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Domatium
A domatium (plural: domatia, from the Latin "domus", meaning home) is a tiny chamber that houses arthropods, produced by a plant. Ideally domatia differ from galls in that they are produced by the plant rather than being induced by their inhabitants, but the distinction is not sharp; the development of many types of domatia is influenced and promoted by the inhabitants. Most domatia are inhabited either by mites or ants, in what can be a mutualist relationship, but other arthropods such as thrips may take parasitic advantage of the protection offered by this structure. Domatia occupied by ants are called myrmecodomatia. An important class of myrmecodomatia comprise large, hollow spines of certain acacias such as '' Acacia sphaerocephala'', in which ants of the genera '' Pseudomyrmex'' and '' Tetraponera'' make their nests. Plants that provide myrmecodomatia are called myrmecophytes. The variety of the plants that provide myrmecodomatia, and the ranges of forms of such domatia ...

Herbivorous
A herbivore is an animal anatomically and physiologically evolved to feed on plants, especially upon vascular tissues such as foliage, fruits or seeds, as the main component of its diet. These more broadly also encompass animals that eat non-vascular autotrophs such as mosses, algae and lichens, but do not include those feeding on decomposed plant matters (i.e. detritivores) or macrofungi (i.e. fungivores). As a result of their plant-based diet, herbivorous animals typically have mouth structures ( jaws or mouthparts) well adapted to mechanically break down plant materials, and their digestive systems have special enzymes (e.g. amylase and cellulase) to digest polysaccharides. Grazing herbivores such as horses and cattles have wide flat- crowned teeth that are better adapted for grinding grass, tree bark and other tougher lignin-containing materials, and many of them evolved rumination or cecotropic behaviors to better extract nutrients from plants. A large per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or 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 motility, 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mites
Mites are small arachnids (eight-legged arthropods) of two large orders, the Acariformes and the Parasitiformes, which were historically grouped together in the subclass Acari. However, most recent genetic analyses do not recover the two as each other's closest relative within Arachnida, rendering the group invalid as a clade. Most mites are tiny, less than in length, and have a simple, unsegmented body plan. The small size of most species makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others are Predation, predators or Parasitism, parasites. This last type includes the commercially destructive ''Varroa'' parasite of honey bees, as well as scabies mites of humans. Most species are harmless to humans, but a few are associated with allergies or may transmit diseases. The scientific discipline devoted to the study of mites is called acarology. Evolution and taxonomy Mites are not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invertebrates
Invertebrates are animals that neither develop nor retain a vertebral column (commonly known as a ''spine'' or ''backbone''), which evolved from the notochord. It is a paraphyletic grouping including all animals excluding the chordate subphylum Vertebrata, i.e. vertebrates. Well-known phyla of invertebrates include arthropods, molluscs, annelids, echinoderms, flatworms, cnidarians, and sponges. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and diversity of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 10 μm (0.0004 in) myxozoans to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are actually sister chordate subphyla to Vertebrata, being more closely related to vertebrates than to other invertebrates. This makes the "invertebrates" paraphyletic, so the term has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
