Answer: Arisaema triphyllum, also known as Indian-turnip, wakerobin, or Jack in the Pulpit, inhabits moist woods and thrives in full shade. The plant has one or two smooth leaves consisting of three leaflets from 3 to 6 inches long and from 1 1/2 to 3 1/2 inches wide. The flower, which is either all green or green with dark purple stripes, is readily recognized on account of the similarity of its form to that of the calla lily. In autumn the fruit ripens in the form of a bunch of bright, scarlet, shining berries. The underground portion, usually referred to as the root but botanically known as a corm, is shaped like a turnip. The lower part is flat and wrinkled, while the upper part is surrounded by coarse wavy rootless. It has an extremely burning taste, and all parts of the plant are considered toxic if consumed.
