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 Cham&lirium luteum, and at one time known 

 as Helonias dioica. After Troth.
