FIG. 272. Swamp Pink (Helonias bullata) is a rather rare plant found only in certain 

 localities, particularly in wet places, extending from southern New York to Virginia. It 

 produces a tuberous root-stock, and the evergreen leaves are clustered near the base of a 

 naked scape which bears in the early spring a short raceme of purplish flowers. This 

 should not be confounded with the plant yielding the drug known as Helonias or false 

 unicorn root, the latter being derived from Chamcelirium luteum, and at one time known 

 as Helonias dioica. After Troth.
