Cicuta virosa L. |

Cicuta virosa (cowbane or northern water hemlock) is a species of Cicuta, native to northern and central Europe, northern Asia and northwestern North America. It is a perennial herbaceous plant which grows up to 1–2 m tall. The stems are smooth, branching, swollen at the base, purple-striped, and hollow except for partitions at the junction of the leaves and stem. In cross section the stems have one flat side and the other sides are rounded. The leaves are alternate, tripinnate, only coarsely toothed, unlike the ferny, lacy leaves found in many other members of the family Apiaceae. The flowers are small, white and clustered in umbrella shaped inflorescences typical of the family. The many flowered umbellets have unequal pedicels that range from 5 to 11 cm long during fruiting. An oily, yellow liquid oozes from cuts to the stems and roots. This liquid has a rank smell resembling that of parsnips or carrots. The plant may be mistaken for parsnip due to its clusters of white tuberous roots.
It grows in wet meadows, along streambanks and other wet and marshy areas.
There has been some dispute whether it was a hemlock of the genus Cicuta or the genus Conium which was used in ancient Greece as state poison. This poison was administered as a method of capital punishment and certainly the Greek philosopher Socrates drank a cup of some kind of hemlock infusion at his execution in 399 BC. Cicuta virosa is however primarily a northern European species, rare or absent from the Mediterranean region, making its use in Greece unlikely. See Poison hemlock for more information.
The typical dose, however, was not always immediately fatal. Sometimes it was necessary to administer a second cup of the poison.
Considering the toxicity of Water Hemlock, this may be a case of misidentification.
In the past, this plant has had a number of colorful names including Beaver-poison, Children's-bane, Snakeweed and Musquash-poison.
