Genera

Hyoscyameae is an Old World tribe of the subfamily Solanoideae of the flowering plant family Solanaceae. It comprises seven genera: Anisodus , Atropa , Atropanthe , Hyoscyamus , Physochlaina , Przewalskia and Scopolia . [1] The genera Atropanthe and Przewalskia are monotypic, the first being endemic to China and the second to Tibet.

All seven genera of the tribe are poisonous and have a long tradition of use as medicinal plants, being rich in tropane alkaloids with anticholinergic properties. [2] Furthermore, the genera Atropa, Hyoscyamus, Scopolia and Physochlaina have furnished entheogens - the first three in the historical context of European witchcraft and, more specifically, of the flying ointments employed in such practices, [3] while the similar chemistry of the remaining genera points to the potential for entheogenic use. Six of the genera have dry, pyxidial fruits i.e. capsules dehiscing by an operculum and thus resembling a pot with a lid. The fruit of the remaining genus Atropa is a glossy, juicy berry, making Atropa species especially dangerous poisonous plants, since - unlike other Hyoscyameae - their attractive fruits may easily be mistaken for edible berries, particularly by children - as has frequently occurred in the case of Atropa belladonna , the infamous Deadly Nightshade. [4]

An eighth genus referable to Hyoscyameae remained unresolved until 2020: the poorly-known, monotypic genus Pauia contained the single species Pauia belladonna Deb and Dutta native to Assam and Arunachal Pradesh. The late Professor Armando Theodoro Hunziker, one of the foremost authorities on the Solanaceae, was of the opinion that Pauia should be subsumed in Atropa. The plant resembles the Indian Atropa acuminata , but differs from it most markedly in bearing a berry that, unlike those of other Atropa species, is not globose but oblong in shape, somewhat resembling that edible Solanaceous fruit the Goji. [5] In 2020, the species was reclassified into genus Atropa as Atropa indobelladonna . [6]

<i>Datura</i> Genus of poisonous, potentially psychoactive plants

Datura is a genus of nine species of highly poisonous, vespertine-flowering plants belonging to the nightshade family (Solanaceae). They are commonly known as thornapples or jimsonweeds, but are also known as devil's trumpets or mad apple. Other English common names include moonflower, devil's weed, and hell's bells. All species of Datura are extremely poisonous and psychoactive, especially their seeds and flowers, which can cause respiratory depression, arrhythmias, fever, delirium, hallucinations, anticholinergic toxidrome, psychosis, and death if taken internally.

<i>Atropa</i> Genus of plants

Atropa is a genus of flowering plants in the nightshade family, Solanaceae: tall, calcicole, herbaceous perennials, bearing large leaves and glossy berries particularly dangerous to children, due to their combination of an attractive, cherry-like appearance with a high toxicity. Atropa species favour temperate climates and alkaline soils, often growing in light shade in woodland environments associated with limestone hills and mountains. Their seeds can remain viable in the soil for long periods, germinating when the soil of sites in which plants once grew is disturbed by human activity or by natural causes, e.g. the windthrow of trees. The best-known member of the genus Atropa is deadly nightshade - the poisonous plant par excellence in the minds of many. The pharmacologically active ingredients of Atropa species include atropine, scopolamine, and hyoscyamine, all tropane alkaloids having anticholinergic, deliriant, antispasmodic and mydriatic properties. The genus is named for Άτροπος (Atropos) - lit. 'she who may not be turned (aside)' - one of the Three Fates and cutter of the thread of life / bringer of death - in reference to the extreme toxicity of A.belladonna and its fellow species - of which four others are currently accepted.

<i>Atropa belladonna</i> Species of toxic flowering plant in the nightshade family.

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 aubergine (eggplant). It is native to Europe and Western Asia, including Turkey. 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, North Africa and the United States.

<span class="mw-page-title-main">Besom</span> Type of broom

A besom is a broom, a household implement used for sweeping. The term is mostly reserved for a traditional broom constructed from a bundle of twigs tied to a stout pole. The twigs used could be broom, heather or similar. The song "Buy Broom Buzzems" from Northern England refers to both types of twig. From the phrase broom besom the more common broom comes. In Scotland and Bulgaria, besoms are still occasionally to be found at the edge of forests where they are stacked for use in early response to an outbreak of fire.

<i>Hyoscyamus niger</i> Species of plant

Henbane is a poisonous plant belonging to tribe Hyoscyameae of the nightshade family Solanaceae. Henbane is native to temperate Europe and Siberia, and naturalised in Great Britain and Ireland.

<span class="mw-page-title-main">Deliriant</span> Class of psychoactive drugs

Deliriants are a subclass of hallucinogen. The term was coined in the early 1980s to distinguish these drugs from psychedelics such as LSD and dissociatives such as ketamine, 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.

<i>Nicandra physalodes</i> Species of flowering plant in the tomato family Solanaceae

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.

<i>Scopolia</i> Genus of flowering plants

Scopolia is a genus of four species of flowering plants in the family Solanaceae, native to Europe and Asia. The genus is named after Giovanni Scopoli (1723–88), a Tyrolean naturalist. The genus has a disjunct distribution, with two recognised species in Central to Eastern Europe,, and two species in East Asia. The two European species are:

<i>Hyoscyamus</i> Genus of flowering plants

Hyoscyamus — known as the henbanes — is a genus of flowering plants in the nightshade family, Solanaceae. It comprises 31 species, all of which are toxic. It, along with other genera in the same family, is a source of the drug hyoscyamine (daturine). Cruciferous type of stomata are present in Hyoscyamus.

<i>Anisodus tanguticus</i> Species of plant

Anisodus tanguticus is a species of flowering plant belonging to tribe Hyoscyameae of subfamily Solanoideae of the nightshade family Solanaceae. It is thus closely related to Henbane and Deadly Nightshade. Solanaceae is a plant family which includes many important agricultural plants such as the potato and the tomato. It is mostly found growing in the Qinghai-Tibetan Plateau. A. tanguticus is collected and used mostly for its medicinal effects caused by the plant's biologically active nicotine and tropane alkaloids. It has a significant impact in China as one of the 50 fundamental herbs used in traditional Chinese medicine.

<span class="mw-page-title-main">Tropane alkaloid</span> Class of chemical compounds

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.

<i>Iochroma arborescens</i> Species of plant

Iochroma arborescens is a species of flowering plant in the genus Iochroma, belonging to the nightshade family Solanaceae. Formerly it was considered the single species in the monotypic genus Acnistus. Common names include gallinero, mata-gallina, fruta-de-sabiá, hollowheart, wild tobacco, siyou, bastard sirio, galán arbóreo, tabaco de monte, nigüito, marieneira, güitite, and tabak djab.

<i>Scopolia carniolica</i> Species of plant

Scopolia carniolica, the European scopolia or henbane bell, is a poisonous plant belonging to tribe Hyoscyameae of the nightshade family Solanaceae. It bears dark brownish-violet nodding flowers on long, slender pedicels. It grows to 60 centimetres (24 in) in height. Its toxicity derives from its high levels of tropane alkaloids, particularly atropine. The concentration of atropine is highest in the roots.

<span class="mw-page-title-main">Solanaceae</span> Family of flowering plants that includes tomatoes, potatoes and tobacco

The Solanaceae, or the nightshades, is 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.

<i>Atropa baetica</i> Species of flowering plant

Atropa baetica, commonly known as the Andalusian belladonna, is one of Europe's rarest wildflowers. A close relative of the infamous deadly nightshade, its specific name derives from that of the Roman province of Hispania Baetica, while its common name refers to the Spanish region of Andalucía – both designating the area in the south of Spain where it is most frequently encountered. It is an attractive perennial plant with a herbaceous habit, bearing infundibuliform, yellow or greenish flowers and shiny, black berries. Like the other three species of Atropa, it is an extremely poisonous plant, containing a variety of tropane alkaloids with anticholinergic, deliriant, antispasmodic and mydriatic properties. Although most populations of the plant are to be found in Spain, it is not wholly confined to the Iberian Peninsula of Europe, occurring also in certain localities in Morocco and Algeria in the Atlas Mountains of North Africa. The Rif and the Baetic System, which face each other across the Alboran Sea, together constitute one of the finest of the Mediterranean biodiversity hotspots – rich in endemic species, of which Atropa baetica is a notable example..

<i>Physochlaina</i> Genus of flowering plants in the nightshade family Solanaceae

Physochlaina is a small genus of herbaceous perennial flowering plants belonging to the nightshade family, Solanaceae, found principally in the north-western provinces of China although one species occurs in Western Asia, while others occur in Siberia, Mongolia and the Chinese autonomous region of Inner Mongolia. Some sources maintain that the widespread species P. physaloides is found also in Japan, but the species is not recorded as being native in one of the few English-language floras of the country. The genus has medicinal value, being rich in tropane alkaloids, and is also of ornamental value, three species having been grown for ornament, although hitherto infrequently outside botanical gardens. Furthermore, the genus contains a species formerly used as an entheogen in Siberia.

<i>Hyoscyamus albus</i> Species of flowering plant
