Apiaceae Family of flowering plants

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. It is the 16th-largest family of flowering plants, with more than 3,700 species in 434 genera including such well-known and economically important plants such as ajwain, angelica, anise, asafoetida, caraway, carrot, celery, chervil, coriander, cumin, dill, fennel, lovage, cow parsley, parsley, parsnip and sea holly, as well as silphium, a plant whose identity is unclear and which may be extinct.

Water dropwort is a common name for several genera of plants and may refer to:

<i>Oenanthe</i> (plant) Genus of flowering plants in the umbellifer family Apiaceae

Oenanthe, known as water dropworts, oenanthes, water parsleys, and water celeries, are a genus of plants in the family Apiaceae. Most of the species grow in damp ground, such as in marshes or in water.

<i>Aethusa cynapium</i> Species of flowering plant in the celery family Apiaceae

Aethusa cynapium is an annual herb in the plant family Apiaceae, native to Europe, western Asia, and northwest Africa. It is the only member of the genus Aethusa. It is related to hemlock and water-dropwort, and like them it is poisonous, though less so than hemlock. It has been introduced into many other parts of the world and is a common weed in cultivated ground.

<i>Cicuta</i> Genus of plants

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 2.5 meters (8.2 ft) 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 other edible and poisonous plants. The common name hemlock may also be confused with poison hemlock, or with the Hemlock tree.

Oenanthotoxin Chemical compound

Oenanthotoxin is a toxin extracted from hemlock water-dropwort and other plants of the genus Oenanthe. It is a central nervous system poison, and acts as a noncompetitive antagonist of the neurotransmitter gamma-aminobutyric acid. A case has been made for the presence of this toxin in local Oenanthe species playing a causative role in euthanasia in ancient Sardinia. It was crystallized in 1949 by Clarke and co-workers. It is structurally closely related to the toxins cicutoxin and carotatoxin. Oenanthotoxin is a C17 polyacetylene isomer of cicutoxin.

Palustris is a Latin word meaning "swampy" or "marshy", and may refer to:

<i>Oenanthe pimpinelloides</i> Species of flowering plant

Oenanthe pimpinelloides is a species of flowering plant in the family Apiaceae known by the common name corky-fruited water-dropwort.

<i>Oenanthe sarmentosa</i> Species of flowering plant

Oenanthe sarmentosa is a species of flowering plant in the family Apiaceae known by the common name water parsley. It is native to western North America from Alaska to California, where it grows in wet areas, such as streambanks. It is sometimes aquatic, growing in the water. The plant has been used in cultivation in wetlands, and the recent discovery of several colonies growing by a stream in Illinois demonstrates its capacity to become a noxious weed if it is introduced elsewhere. This is a perennial herb growing to a maximum height near 1.5 meters. The leaves have blades up to 30 centimeters long borne on petioles up to 35 centimeters in length. The parsley-like leaf blade is divided into serrated, lobed leaflets. The inflorescence is a compound umbel of many flowers with bright white to red-tinged petals.

<i>Oenanthe javanica</i> Species of plant

Oenanthe javanica, commonly Java waterdropwort, water celery, water dropwort, Chinese celery, and Japanese parsley, is a plant of the genus Oenanthe originating from East Asia. It has a widespread native distribution in temperate Asia and tropical Asia, and is also native to Queensland, Australia.

<i>Oenanthe crocata</i> Species of flowering plant

Oenanthe crocata, the hemlock water-dropwort, is a flowering plant in the carrot family, Apiaceae. Scientists at the University of Eastern Piedmont in Italy wrote that they had identified Oenanthe crocata as the plant responsible for producing the sardonic grin. This plant is a possible candidate for the "sardonic herb", which was a neurotoxic plant referred to in ancient histories. It was purportedly used for the ritual killing of elderly people and criminals in Nuragic Sardinia. The subjects were intoxicated with the herb and then dropped from a high rock or beaten to death.

<i>Oenanthe aquatica</i> Species of flowering plant

Oenanthe aquatica, known in English as fineleaf water dropwort or fine-leaved water dropwort is an aquatic flowering plant in the family Apiaceae.
