Description.—Purple trillium is a low-growing plant from 8 to 16 inches in height, with a rather stout stem having three leaves arranged in a circle near the top. These are from 3 to 7 inches in length and of about the same width and are practically stemless. The flower, which appears from April to June, is borne singly at the end of the stem on a slender stalk. Its parts are arranged in threes which feature serves to identify the plant. The three petals, which are 1 1/4 inches long and one-half inch wide, are dark purple pink, greenish, or white. The flower has an unpleasant odor. It is followed by a reddish berry.

Part used.—The root, collected toward the close of summer.
