Mimosa Verrucosa
''Mimosa verrucosa'', commonly known as jurema-branca ("white jurema") or jurema-de- oeiras, is a species of legume of the genus ''Mimosa'', in the common bean family, Fabaceae. It is a shrub or small tree native to Brazil (Bahia, Ceará, Paraíba, Pernambuco and Rio Grande do Norte). It has "near threatened" conservation status as a result of human‐caused deforestation in arid to semi-arid regions of Northeastern Brazil. Growth The tree grows to about 2.5 to 5 m tall and has blossoms that are pink cylindrical spikes. The blossom filaments are pink and the anthers are cream colored. Uses The wood of the tree is used for making charcoal, firewood and wooden stakes. The bark is used for medicine. Characteristics ''Mimosa verrucosa'' has been proven to be a very important provider of pollen for ''Apis mellifera'', the European honey bee.

George Bentham
George Bentham (22 September 1800 – 10 September 1884) was an English botanist, described by the weed botanist Duane Isely as "the premier systematic botanist of the nineteenth century". Born into a distinguished family, he initially studied law, but had a fascination with botany from an early age, which he soon pursued, becoming president of the Linnaean Society in 1861, and a fellow of the Royal Society in 1862. He was the author of a number of important botanical works, particularly flora. He is best known for his taxonomic classification of plants in collaboration with Joseph Dalton Hooker, his ''Genera Plantarum'' (1862–1883). He died in London in 1884. Life Bentham was born in Stoke, Plymouth, on 22 September 1800. His father, Sir Samuel Bentham, a naval architect, was the only brother of Jeremy Bentham to survive into adulthood. His mother, Mary Sophia Bentham, was a botanist and author. Bentham had no formal education but had a remarkable linguistic aptitude. By ...

Northeast Region, Brazil
The Northeast Region of Brazil ( ) is one of the five official and political regions of the country according to the Brazilian Institute of Geography and Statistics. Of Brazil's twenty-six states, it comprises nine: Maranhão, Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Sergipe and Bahia, along with the Fernando de Noronha archipelago (formerly a separate territory, now part of Pernambuco). Chiefly known as ''Nordeste'' ("Northeast") in Brazil, this region was the first to be colonized by the Portuguese and other European peoples, playing a crucial role in the country's history. ''Nordestes dialects and rich culture, including its folklore, cuisines, music and literature, became the most easily distinguishable across the country. To this day, ''Nordeste'' is known for its history and culture, as well as for its natural environment and its hot weather. ''Nordeste'' stretches from the Atlantic seaboard in the northeast and southeast, northwest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medicinal Plants
Medicinal plants, also called medicinal herbs, have been discovered and used in traditional medicine practices since prehistoric times. Plants synthesize hundreds of chemical compounds for various functions, including Plant defense against herbivory, defense and protection against insects, fungi, Plant disease resistance, diseases, against parasites and herbivorous mammals. The earliest historical records of herbs are found from the Sumerian civilization, where hundreds of medicinal plants including opium are listed on clay tablets, . The Ebers Papyrus from ancient Egypt, , describes over 850 plant medicines. The Greek physician Pedanius Dioscorides, Dioscorides, who worked in the Roman army, documented over 1000 recipes for medicines using over 600 medicinal plants in , ; this formed the basis of pharmacopoeias for some 1500 years. Drug research sometimes makes use of ethnobotany to search for pharmacologically active substances, and this approach has yielded hundreds of use ...

Forages
Foraging is searching for wild food resources. It affects an animal's Fitness (biology), fitness because it plays an important role in an animal's ability to survive and reproduce. Optimal foraging theory, Foraging theory is a branch of behavioral ecology that studies the foraging behavior of animals in response to the environment where the animal lives. Behavioral ecologists use economic models and categories to understand foraging; many of these models are a type of optimal model. Thus foraging theory is discussed in terms of optimizing a payoff from a foraging decision. The payoff for many of these models is the amount of energy an animal receives per unit time, more specifically, the highest ratio of energetic gain to cost while foraging. Foraging theory predicts that the decisions that maximize energy per unit time and thus deliver the highest payoff will be selected for and persist. Key words used to describe foraging behavior include ''resources'', the elements necessary fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Brazil
The wildlife of Brazil comprises all naturally occurring animals, plants, and fungus, fungi in the South American country.

Psychedelic Plants
Psychoactive plants are plants, or preparations thereof, that upon ingestion induce psychotropic effects. As stated in a reference work: Psychoactivity may include sedative, stimulant, euphoric, deliriant, and hallucinogenic effects. Several hundred psychoactive plants are known. Some popular examples of psychoactive plants include ''Coffea arabica'' (coffee), ''Camellia sinensis'' (tea), ''Nicotiana tabacum'' (tobacco), and ''Cannabis'' (including hashish). Psychoactive plants have been used ritually (''e.g.'', peyote as an entheogen), medicinally (''e.g.'', opium as an analgesic), and therapeutically (''e.g.'', cannabis as a drug) for thousands of years. Hence, the sociocultural and economic significance of psychoactive plants is enormous. History of psychoactive plants Many plants contain substances that alter moods and cause euphoria. Some of these psychoactive plants were known to the ancients. The history of poppy cultivation dates back to 3400 BC. In Mesopotamia. P ...

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 ...

Apis Mellifera
The western honey bee or European honey bee (''Apis mellifera'') is the most common of the 7–12 species of honey bees worldwide. The genus name ''Apis'' is Latin for 'bee', and ''mellifera'' is the Latin for 'honey-bearing' or 'honey-carrying', referring to the species' production of honey. Like all honey bee species, the western honey bee is eusocial, creating colonies with a single fertile female (or "queen"), many normally non-reproductive females or "workers", and a small proportion of fertile males or " drones". Individual colonies can house tens of thousands of bees. Colony activities are organized by complex communication between individuals, through both pheromones and the waggle dance. The western honey bee was one of the first domesticated insects, and it is the primary species maintained by beekeepers to this day for both its honey production and pollination activities. With human assistance, the western honey bee now occupies every continent except Antarctica. Wes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollen
Pollen is a powdery substance produced by most types of flowers of seed plants for the purpose of sexual reproduction. It consists of pollen grains (highly reduced Gametophyte#Heterospory, microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male Conifer cone, cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it Germination, germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and Forensic science, forensics. Pollen in plants is used for transferring Ploidy#Haploid and monoploid, haploid male genetic ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mimosa Verrucosa02
''Mimosa'' is a genus of about 600 species of herbs and shrubs, in the mimosoid clade of the legume family Fabaceae. Species are native to the Americas, from North Dakota to northern Argentina, and to eastern Africa (Tanzania, Mozambique, and Madagascar) as well as the Indian subcontinent and Indochina. The generic name is derived from the Greek word (''mimos''), 'actor' or 'mime', and the feminine suffix -''osa'', 'resembling', suggesting its 'sensitive leaves' which seem to 'mimic conscious life'. Two species in the genus are especially notable. One is ''Mimosa pudica'', commonly known as touch-me-not, which folds its leaves when touched or exposed to heat. It is native to southern Central and South America but is widely cultivated elsewhere for its curiosity value, both as a houseplant in temperate areas, and outdoors in the tropics. Outdoor cultivation has led to weedy invasion in some areas, notably Hawaii. The other is ''Mimosa tenuiflora'', which is best known for its ...

Charcoal
Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning, often by forming a charcoal kiln, the heat is supplied by burning part of the starting material itself, with a limited supply of oxygen. The material can also be heated in a closed retort. Modern charcoal briquettes used for outdoor cooking may contain many other additives, e.g. coal. The early history of wood charcoal production spans ancient times, rooted in the abundance of wood in various regions. The process typically involves stacking wood billets to form a conical pile, allowing air to enter through openings at the bottom, and igniting the pile gradually. Charcoal burners, skilled professionals tasked with managing the delicate operation, often lived in isolation to tend their wood piles . Throughout histo ...

Anthers
The stamen (: stamina or stamens) is a part consisting of the male reproductive organs of a flower. Collectively, the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains microsporangia. Most commonly, anthers are two-lobed (each lobe is termed a locule) and are attached to the filament either at the base or in the middle area of the anther. The sterile (i.e. nonreproductive) tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The size of anthers differs greatly, from a tiny fraction of a millimeter in ''Wolfia'' spp up to five inches (13 centimeters) in '' Canna iridiflora'' and '' Strelitzia nicolai''. The stamens in a flower are collectively called the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
