Datura stramonium, known by the common names thorn apple, jimsonweed, devil's snare, or devil's trumpet, is a poisonous flowering plant of the nightshade family Solanaceae. It is a species belonging to the Datura genus and Daturae tribe. Its likely origin was in Central America, and it has been introduced in many world regions. It is an aggressive invasive weed in temperate climates across the world. D. stramonium has frequently been employed in traditional medicine to treat a variety of ailments. It has also been used as a hallucinogen, taken entheogenically to cause intense, sacred or occult visions. It is unlikely ever to become a major drug of abuse owing to effects upon both mind and body frequently perceived as being highly unpleasant, giving rise to a state of profound and long-lasting disorientation or delirium with a potentially fatal outcome. It contains tropane alkaloids which are responsible for the psychoactive effects, and may be severely toxic.
Atropa belladonna, commonly known as belladonna or deadly nightshade, is a toxic perennial herbaceous plant in the nightshade family Solanaceae, which also includes tomatoes, potatoes, and eggplant (aubergine). It is native to Europe, North Africa, and Western Asia. Its distribution extends from Ireland in the west to western Ukraine and the Iranian province of Gilan in the east. It is also naturalised or introduced in some parts of Canada and the United States.
Brugmansia is a genus of seven species of flowering plants in the nightshade family Solanaceae. They are woody trees or shrubs, with pendulous flowers, and have no spines on their fruit. Their large, fragrant flowers give them their common name of angel's trumpets, a name sometimes used for the closely related genus Datura.
Strychnos is a genus of flowering plants, belonging to the family Loganiaceae. The genus includes about 100 accepted species of trees and lianas, and more than 200 that are as yet unresolved. The genus is widely distributed around the world's tropics and is noted for the presence of poisonous indole alkaloids in the roots, stems and leaves of various species. Among these alkaloids are the well-known and virulent poisons strychnine and curare.
Deliriants are a subclass of hallucinogen. The term was coined in the early 1980s to distinguish these drugs from psychedelics and dissociatives such as LSD and ketamine, respectively, due to their primary effect of causing delirium, as opposed to the more lucid and less disturbed states produced by other types of hallucinogens. The term generally refers to anticholinergic drugs, which are substances that inhibit the function of the neurotransmitter acetylcholine. Common examples of deliriants include plants of the genera Datura and Brugmansia as well as higher than recommended dosages of diphenhydramine (Benadryl). A number of plant deliriants such as that of the Solanaceae family, particularly in the Americas have been used by some indigenous cultures to reach delirious and altered states for traditions or rituals, such as rites of passage, divination or communicating with the ancestors. Despite their long history of use, deliriants are the least-studied class of hallucinogens in terms of their behavioral and neurological effects.
Nicandra physalodes is a species of flowering plant in subfamily Solanoideae of the nightshade family. It is known by the common names apple-of-Peru and shoo-fly plant. It is thought originally to have been native to western South America, including Peru, and is known elsewhere as an introduced and ruderal species – sometimes as a weed – in tropical, subtropical and, to a lesser extent, temperate areas all over the world. It has also long been cultivated as an ornamental plant for its attractive flowers and curious fruits and has been adopted into the traditional medicine of countries far-removed from its original home.
Solanum americanum, commonly known as American black nightshade, small-flowered nightshade or glossy nightshade, is a herbaceous flowering plant of wide though uncertain native range. The certain native range encompasses the tropics and subtropics of the Americas, Melanesia, New Guinea, and Australia.
Calystegia sepium is a species of flowering plant in the family Convolvulaceae. It has a subcosmopolitan distribution throughout temperate regions of the North and South hemispheres.
Avicennia is a genus of flowering plants currently placed in the bear's breeches family, Acanthaceae. It contains mangrove trees, which occur in the intertidal zones of estuarine areas and are characterized by its "pencil roots", which are aerial roots. They are also commonly known as api api, which in the Malay language means "fires", a reference to the fact that fireflies often congregate on these trees. Species of Avicennia occur worldwide south of the Tropic of Cancer.
Avicennia marina, commonly known as grey mangrove or white mangrove, is a species of mangrove tree classified in the plant family Acanthaceae. As with other mangroves, it occurs in the intertidal zones of estuarine areas.
Rhizophora is a genus of tropical mangrove trees, sometimes collectively called true mangroves. The most notable species is the red mangrove but some other species and a few natural hybrids are known. Rhizophora species generally live in intertidal zones which are inundated daily by the ocean. They exhibit a number of adaptations to this environment, including pneutomatophores that elevate the plants above the water and allow them to respire oxygen even while their lower roots are submerged and a cytological molecular "pump" mechanism that allows them to remove excess salts from their cells. The generic name is derived from the Greek words ριζα (rhiza), meaning "root," and φορος (phoros), meaning "bearing," referring to the stilt-roots.
Heritiera littoralis, commonly known as the looking-glass mangrove or tulip mangrove, is a mangrove tree in the family Malvaceae native to coastal areas of eastern Africa, Asia, Melanesia and northern Australia. The common name refers to the silvery appearance of the underside of the leaves, resembling a mirror to some degree. The strong timber has uses in marine applications and elsewhere.
The red-headed myzomela or red-headed honeyeater is a passerine bird of the honeyeater family Meliphagidae found in Australia, Indonesia, and Papua New Guinea. It was described by John Gould in 1840. Two subspecies are recognised, with the nominate race M. e. erythrocephala distributed around the tropical coastline of Australia, and M. e. infuscata in New Guinea. Though widely distributed, the species is not abundant within this range. While the IUCN lists the Australian population of M. e. infuscata as being near threatened, as a whole the widespread range means that its conservation is of least concern.
Bruguiera gymnorhiza, the large-leafed orange mangrove or oriental mangrove,) is a mangrove tree that grows usually to 7-20m high, but sometimes up to 35m, that belongs to the family Rhizophoraceae. It is found on the seaward side of mangrove swamps, often in the company of Rhizophora. It grows from the Western Pacific across Indian Ocean coasts to Cape Province, South Africa.
Tropane alkaloids are a class of bicyclic [3.2.1] alkaloids and secondary metabolites that contain a tropane ring in their chemical structure. Tropane alkaloids occur naturally in many members of the plant family Solanaceae. Certain tropane alkaloids such as cocaine and scopolamine are notorious for their psychoactive effects, related usage and cultural associations. Particular tropane alkaloids such as these have pharmacological properties and can act as anticholinergics or stimulants.
Methylatropine is a belladonna derivative.
Bruguiera is a plant genus in the family Rhizophoraceae. It is a small genus of five mangrove species and three hybrids of the Indian and west Pacific Ocean region, its range extending from East Africa and Madagascar through coastal India, Sri Lanka and Southeast Asia to northern Australia, Melanesia and Polynesia. It is characterised by calyces with 8-16 lanceolate, pointed lobes, 16-32 stamens, explosive release of pollen, and viviparous propagules. It is named in honour of French explorer and biologist Jean Guillaume Bruguière (1750–1798). Recently, the eighth taxa of Bruguiera, B. × dungarra was recognised as occurring in northern Australia.
Excoecaria agallocha, a mangrove species, belongs to the genus Excoecaria of the family Euphorbiaceae. The species has many common names, including blind-your-eye mangrove, blinding tree, buta buta tree, milky mangrove, poisonfish tree, and river poison tree. Most of the names refer to its toxic properties or its propensity to cause blindness when its latex comes into contact with the eyes.
Bruguiera cylindrica is a mangrove in the family Rhizophoraceae. It grows in mangrove swamps in tropical Asia.
The Solanaceae, or nightshades, are a family of flowering plants that ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell and chili peppers—are used as food. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida (dicotyledons). The Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology.
