A tall shrub consisting of a single stout stem covered with long sharp spines, which are extremely poisonous. It usually grows about six or eight feet high, and has huge palm-like leaves, which are also prickly. The flowers grow in a dense cluster at the top of the stem, and in time turn into bright red berries.

This plant should be carefully avoided in the forests. It has been rightly named "Devil's Club," since no human being may touch it with impunity.
