adopted for this species the name A . striata Michx. See under that 

 species, where the case is discussed in full. 



Agrimonia microcarpa Wallroth. The first name for this 

 species was A. pumila Muhl., printed in his Catalogue. The only 

 thing said about this species beside the name is: "Small, Miss.," 

 which means that the trivial name is small agrimony and that it 

 grows in Mississippi. Now the only small agrimony growing in 

 Mississippi is the present species and Mr. Bicknell evidently 

 identified Agrimonia pumila Muhl. correctly. It had never been 

 published under that name however, before Bicknell adopted it 

 in his paper. There is no question that the species that Bicknell 

 had in mind and that I now discuss is A. pumila Muhl. There is 

 even more doubt that A. microcarpa Wallr. belongs to this plant. 

 Wallroth cites three specimens: Pennsylvania (Moser), southern 

 Georgia (Beyrich), and Jalapa (Schiede). As there is no indication 

 of type, the first specimen should be regarded as such. I have 

 seen no specimen of it from Pennsylvania, the nearest being from 

 Maryland. In the former state it is represented by A. platycarpa 

 Wallr. It is not likely that Wallroth should have confused the 

 two species, as he is the author of both. Beyrich's plant undoubt- 

 edly belongs to A. microcarpa as here understood, but Schiede's 

 plant from Jalapa, Mexico, belongs to A. Pringlei. The latter 

 is glandular-granuliferous and must, therefore, be placed near 

 A. striata. No one before Bicknell seems to have noticed the 

 tuberous character of A. microcarpa and the other non-glandular 

 species. This is not found in A. Pringlei. 



Agrimonia platycarpa Wallr. This has not been recognized 

 since Wallroth's time. It is closely related to A. microcarpa. In 

 the latter the leaves are situated near the base of the stem, having 

 either 3 leaflets of nearly the same size, or else also an additional 

 much smaller pair below. In A. platycarpa the leaflets are 5 or 

 7 and the lower only slightly reduced. The fruit in A. platycarpa 

 is broader than in A. microcarpa, usually broader than long, 

 and with a more prominent flange or rim. Its range is more 

 northern than that of A. microcarpa. 



Agrimonia pubescens Wallr. This was first distinguished by 

 Torrey & Gray under the name Agrimonia Eupatoria mollis. It 

 was raised to specific rank by Britton,* following the Madison 



* Bull. Torrey Club 19: 221. 1894.
