Oenanthe (plant)
''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. 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, and is considered particularly dangerous because of its similarity to several edible plants. The species '' O. javanica'', commonly known as Chinese celery or Japanes ...

''secalinum'' which is also called "Chinese celery", or other plants called " water dropwort" and " water celery".

Ranunculus Sceleratus
''Ranunculus sceleratus'' known by the common names celery-leaved buttercup, celery-leaf buttercup, and cursed buttercup is a species of flowering plant in the buttercup family Ranunculaceae. It has a circumpolar distribution in the northern hemisphere, native to temperate and boreal North America and Eurasia, where it grows in wet and moist habitats, including ponds and streambanks. Description ''Ranunculus sceleratus'' is an annual herb growing up to half a meter tall. The leaves are more or less glabrous (hairless) and have small blades each deeply lobed or divided into three leaflets. They are borne on long petioles. The flowers are 5-10mm across with five or fewer yellow petals a few millimeters long and reflexed sepals. The fruit is an achene borne in a cluster of several. While buttercups are toxic due to the presence of the substance protoanemonin, this applies in particular for the cursed buttercup: it is the most toxic buttercup and contains 2.5% protoanemonin.

Vallisneria
''Vallisneria'' (named in honor of Antonio Vallisneri) is a genus of freshwater aquatic plant, commonly called eelgrass, tape grass or vallis. The genus is widely distributed in tropical and subtropical regions of Asia, Africa, Europe, and North America. ''Vallisneria'' is a submerged plant that spreads by runners and sometimes forms tall underwater meadows. Leaves arise in clusters from their roots. The leaves have rounded tips, and definite raised veins. Single white female flowers grow to the water surface on very long stalks. Male flowers grow on short stalks, become detached, and float to the surface. It is dioecious, with male and female flowers on separate plants. The fruit is a banana-like capsule having many tiny seeds. Sometimes it is confused with the superficially similar ''Sagittaria'' when grown submerged. This plant should not be confused with ''Zostera'' species, marine seagrasses that are usually also given the common name "eelgrass". ''Vallisneria'' has arche ...
