"According to Bicknell (Bui. Torr. Bot. Club, 23: 508-525, 1896), the name Aqrimonia nipatoria L 

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

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

 Britton (Bui. Torr. Bot. Club, 18 : 3titi, 1891) states that the true Afirimtmia eupatoria is not known at 

 all as an American plant. The native plant to which the name Aiirimonia eupatoria has been most 

 frequently applied by American authors is Aririmonia liiiviitn (Muhl.) Bicknell. 



fiThename " true unicorn-root " has long been api)licd to Aletris farinosa, b\it as "unicorn-root" 

 was the common name first given to ChamacHrium hileinii. (IMonias dioira). this should more prop- 

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