Agrimonia Bicknellii (Kearney) Rydb. This was well de- 

 scribed by Mr. Bicknell* as a variety of A. mollis, but without a 

 varietal name. This was supplied a year later by Mr. Kearney. 

 It is true that the characters separating A. pubescens (= A. 

 mollis) and this species are not absolute and that intermediate 

 forms are not lacking. A. pubescens is at home in the central 

 states west of the Alleghenies, but extends east thereof into Vir- 

 ginia and Georgia. The home of A. Bicknellii is the Atlantic 

 coast, but it is found as far west as Pennsylvania and Tennessee. 

 In the Mississippi valley only A. pubescens is found and on the 

 Atlantic border only typical A. Bicknellii. The intermediate 

 forms are found in the Alleghenian region, where the ranges of 

 the two overlap. These two species are the nearest American 

 representatives of the European A. Eupatoria, but have much 

 smaller fruit. Especially is A. Bicknellii sometimes hard to 

 distinguish from A. Eupatoria without the fruit. Two western 

 specimens in the United States National Herbarium I have de- 

 termined doubtfully as A. Bickfiellii, viz. one collected at Fort 

 Snelling, Minnesota, by Mearns, and the other at Naperville, 

 Illinois, by Umbach. They may belong to A. Eupatoria L. 



Agrimonia Eupatoria L. Britton and Bicknell believed that 

 this species was not found at all in America. No specimen has been 

 seen from the East, where the species is most likely to be found 

 introduced. There are, however, two specimens, one in the 

 National Herbarium and one in the herbarium of the Missouri 

 Botanical Garden, which without any doubt belong to the species. 

 Holzinger's specimen, especially, has the fruit so well developed 

 that there is no question of the identity. The specimens are: 



Minnesota: Winona, 1889, Holzinger. 



Wisconsin: Mirror Lake, 1903, Eggert. 



Agrimonia striata Michx. This species has been badly mis- 

 understood. Probably the real cause of this is that in Michaux's 

 herbarium there are two specimens on the sheet of A. striata. 

 The left-hand specimen represents the plant, here treated under 

 that name, and the right-hand specimen is one of A. rostellata.
