Conium
''Conium'' ( or ) is a genus of flowering plants in the family Apiaceae. , Plants of the World Online accepts six species. All species of the genus are poisonous to humans. ''C. maculatum'', also known as hemlock, is infamous for being highly poisonous. Hemlock is native to temperate regions of Europe, North Africa and Western Asia. The species ''C. chaerophylloides'', ''C. fontanum'', and ''C. sphaerocarpum'' are all native to southern Africa. Description Plants of the genus ''Conium'' are eudicots, flowering plants distinguished by their two cotyledons (embryonic leaves) and tricoplate (three-pored) pollen. They are typically biennial, forming basal rosettes in the first year of growth, and sprouting a rigid, hollow flower stalk in the second. Germination occurs between spring and autumn. Occasionally, plants which germinate in early spring are annual instead of biennial. These plants grow best in wet, poorly drained areas with nutrient rich soil. They grow well in nitrogen ...

Conium Maculatum
''Conium maculatum'', colloquially known as hemlock, poison hemlock or wild hemlock, is a highly poisonous biennial herbaceous flowering plant in the carrot family Apiaceae, native to Europe and North Africa. A hardy plant capable of living in a variety of environments, hemlock is widely naturalized in locations outside its native range, such as parts of Australia, West Asia, and North and South America, to which it has been introduced. It is capable of spreading and thereby becoming an invasive weed. All parts of the plant are toxic, especially the seeds and roots, and especially when ingested. Under the right conditions the plant grows quite rapidly during the growing season and can reach heights of , with a long penetrating root. The plant has a distinctive odour usually considered unpleasant that carries with the wind. The hollow stems are usually spotted with a dark maroon colour before the plant dies and becomes dry and brown after completing its biennial lifecycle. ...

Coniine
Coniine is a poisonous chemical compound, an alkaloid present in and isolable from poison hemlock ('' Conium maculatum''), where its presence has been a source of significant economic, medical, and historico-cultural interest; coniine is also produced by the yellow pitcher plant ('' Sarracenia flava''), and fool's parsley (''Aethusa cynapium''). Its ingestion and extended exposure are toxic to humans and all classes of livestock; its mechanism of poisoning involves disruption of the central nervous system, with death caused by respiratory paralysis. The biosynthesis of coniine contains as its penultimate step the non-enzymatic cyclisation of 5-oxooctylamine to γ-coniceine, a Schiff base differing from coniine only by its carbon-nitrogen double bond in the ring. This pathway results in natural coniine that is a mixture—a racemate—composed of two enantiomers, the stereoisomers (''S'')-(+)-coniine and (''R'')-(−)-coniine, depending on the direction taken by the chain that b ...

Cicuta
''Cicuta'', commonly known as water hemlock, is a genus of four species of highly poisonous plants in the family Apiaceae. They are perennial herbaceous plants which grow up to tall, having distinctive small green or white flowers arranged in an umbrella shape (umbel). Plants in this genus may also be referred to as cowbane or poison parsnip. ''Cicuta'' is native to temperate regions of the Northern Hemisphere, mainly North America and Europe, typically growing in wet meadows, along streambanks and other wet and marshy areas. These plants bear a close resemblance to other members in the family Apiaceae and may be confused with a number of edible or poisonous plants. The common name hemlock may also be confused with poison hemlock (''Conium maculatum''), or with the Hemlock tree. Water hemlock is considered one of North America's most toxic plants, being highly poisonous to humans. Three members of the genus contain a toxin named cicutoxin which causes central nervous system s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Apiaceae
Apiaceae or Umbelliferae is a family of mostly aromatic flowering plants named after the type genus '' Apium'' and commonly known as the celery, carrot or parsley family, or simply as umbellifers.

N-Methylconiine
''N''-Methylconiine is a poisonous alkaloid found in poison hemlock in small quantities. Isolation and properties The -(+)-stereoisomer of ''N''-methylconiine is reported to occur in hemlock in small quantities, and methods for its isolation are described by Wolffenstein and by von Braun. It is a colourless, oily, coniine-like liquid, specific rotation sub>D +81.33° at 24.3 °C. The salts are crystalline ("B" marks one molecule of the base): the hydrochloride, B•HCl, forms masses of needles, mp. 188 °C; the platinichloride, B2•H2PtCl6, has mp. 158 °C. The -(−)-stereoisomer was obtained by Ahrens from residues left in the isolation of coniine as hydrobromide or by removing coniine as the nitroso-compound. It is a colourless, coniine-like liquid, bp. 175.6 °C/767 mmHg, specific rotation sub>D −81.92° at 20 °C. The monohydrochloride crystallises in leaflets, mp. 191–192 °C; the monohydrobromide in leaflets, mp. 189–190 °C; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apioideae
This is a list of genera belonging to the family Apiaceae. It contains all the genera accepted by Plants of the World Online (PoWO) . A few extra genus names are included that PoWO regards as synonyms. Unless otherwise indicated, the placement of genera into sub-taxa is based on the taxonomy used by the Germplasm Resources Information Network (GRIN). "Not assigned" means either that the genus is unplaced in GRIN or that it is not listed by GRIN. Not assigned to a subfamily In a 2021 molecular phylogenetic study, the ''Platysace'' clade and the genera ''Klotzschia'' and ''Hermas'' fell outside the four subfamilies.
