Distinguishing featuresThe 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. |
