Arisaema species

JACK-IN-THE-PULPIT

Distinguishing features
The most distinguishing feature of this plant (found commonly in the woods) is the flower part. There is a flap-like spathe that is green or purplish brown, often striped, and curves gracefully over the club-shaped spadix (the "Jack" or preacher) in his canopied pulpit). The flowers (and eventually a cluster of scarlet berries) form from the base of this spadix. Leaves: one or two long, stalked leaves that are three-parted.
Description
Herbs with pinnately compound leaves. Green or white spathes form hoods over spadices. Imperfect flowers emerge from the base of the spadices, berries are small and orange-red.
Geographic range
Found in moist or shaded areas of the eastern United States.
Toxic principle
Sheep are most likely to be affected but do not commonly show clinical signs.
Diagnosis
Clinical signs
Arisaema causes contact irritation and is of little toxicologic importance because it is seldom consumed by livestock.
