Conium

picture info	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 ...

picture info	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. The ...

picture info	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 ...
