« According to Bicknell (Bui. Torr. Bot. Club, 23:508-525, 1896), the name Agrimonia eupatoria L., 

 long used in local floras and text-books for the agrimony of the Eastern States, has been doing dutv 

 for a group of related species, of which at least five are now clearly recognized. Furthermore, Doctor 

 Britton (Bui. Torr. Bot. Club, 18:366, 1891) states that the true Agrimonia eupatoria is not known at 

 all as an American plant, The native plant to which the name Agrimonia eupatoria has been most 

 frequently applied by American authors is Agrimonia hirsuta (Muhl.) Bicknell. 



bThename " true unicorn-root " has long been applied to Aletris farinosa, but as "unicorn-root" 

 was the common name first given to Chamaelirium luteum (Helonias dioica), this should more prop- 

 erly be called the true unicorn-root and Aletris farinosa the false unicorn-root.
