Not to be confused with : Celery-leaved Crowfoot (which belongs to the same Buttercup Family) [plants with similar names],

Some similarities to : other Buttercups

Uniquely identifiable characteristics

Distinguishing Feature : The shiny dark-green leaves and the elongated fruits separate this from other Buttercups. One of only three Buttercup species (Lesser Spearwort, Greater Spearwort and Creeping Buttercup) that loves shallow water or marsh.

No relation to : Wild Celery [a plant with similar name].

Habitat: Likes marshes, shallow fresh water, banks of streams, wet mud, ponds, ditches and similar wet places.

It has an acrid taste and is poisonous, containing Ranunculin which is converted to the poisonous Protoanemonin by the action of enzymes, which it contains and are released on damage. On the skin the sap will cause severe irritation and blisters with ulceration. If eaten, diarrhoea, abdominal pains, tinnitus, headache, dizziness, seizures, tachycardia, nephritis and perhaps death by respiratory and cardiac arrest. Accidental poisoning of cattle is more common.
