Contrast between hemlock water dropwort (Oenanthe crocata, right) and poison hemlock (Conium maculatum, spotted stems on left)

Oenanthe, known as water dropworts, oenanthes,[2] water parsleys,[3] and water celeries,[4] are a genus of plants in the family Apiaceae. Most of the species grow in damp ground, such as in marshes or in water.

Several of the species are extremely poisonous, the active poison being oenanthotoxin. The most notable of these is O. crocata, which lives in damp, marshy ground, and resembles celery with roots like a bunch of large white carrots. The leaves may be eaten safely by livestock, but the stems, and especially the carbohydrate-rich roots are much more poisonous. Animals familiar with eating the leaves may eat the roots when these are exposed during ditch clearance – one root is sufficient to kill a cow, and human fatalities are also known. It has been referred to as the most poisonous of all British plants,[5] and is considered particularly dangerous because of its similarity to several edible plants.[6]

The species O. javanica, commonly known as Chinese celery or Japanese parsley (seri; not to be confused with mitsuba or Japanese wild celery, Cryptotaenia japonica) is edible and grown in several countries of eastern Asia, as well as in Italy and India, where the spring growth is relished as a vegetable.

Taxonomy and naming[]

"Oenanthe" is derived from the Greek oinos "wine" and anthos "flower", from the wine-like scent of the flowers.[7]

The name "water dropwort" comes from the close resemblance of some of the smaller species (which mainly grow in wet ground) to dropwort, Filipendula vulgaris (Rosaceae), an unrelated plant of dry grasslands.

Species[]

As of 2020, Kew's Plants of the World Online accepts 33 species of Oenanthe:[1]

Sardonic grin[]

Scientists at the University of Eastern Piedmont in Italy wrote that they had identified hemlock water dropwort (Oenanthe crocata) as the plant responsible for producing the sardonic grin.[8][9] 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, in which they were intoxicated with the herb and then dropped from a high rock or beaten to death.[10][11]

Fossil record[]

Oenanthe aquatica fossil fruit halves have been recorded from Upper Miocene of Bulgaria, Pliocene of Thuringia and the Pliocene and Pleistocene of Poland.[12]
