and A. pubescens, and which may ultimately be found in 
northeastern Missouri. 
Muhlenberg, in 1813, indicated A. pumila as a good species 
but unfortunately did not describe it, and also deseribed A. 
Eupatoria, var. hirsuta, which eighty-three years later was 
raised to specific rank. Torrey and Gray, in 1840, described 
A, Eupatoria, var. mollis, which fifty-two years afterward 
was described as a species. Wallroth, in 1842, monographed 
the genus, giving six of our species, one, A. microcarpa, hav- 
ing been described as A. pumila by Muhlenberg. Most of 
Wallroth’s names are valid and are the ones that will be 
accepted in American botany. 
Britton, in 1892, half a century since any work was done 
on the genus, described A. mollis, based on the A. Eupatoria, 
var. mollis of Torrey and Gray. Bicknell, in 1896, raised 
Muhlenberg’s 4. Eupatoria, var. hirsuta to specific rank, 
giving at the same time a description of this and a new spe- 
cies, 4. Drittoniana. He was apparently unaware that Wall- 
roth had already described the former species as A. gryp- 
osepala, and that the latter was described by Michaux in 
1803 as A. striata. Kearney, in 1897, described a variety, 
A, mollis, var. Bicknellii, which afterwards was found to be 
the same as A. mollis, described by Wallroth in 1842 as 
A, pubescens. 
Prior to 1893, when Britton’s ‘Manual’ began to influence 
the names in this genus, but three specific names were in 
use for species of Agrimonia in the eastern states, A. Eu- 
patoria, A. parviflora, and A. striata, the latter not being 
mentioned in any manual or flora of recent date, and the 
name applied also to both A. rostellata and A. pubescens. 
Muhlenberg, in his ‘Catalogue,’ recognized and indicated 
several species and varieties in this genus, but these were 
not accepted until after 1891, and his names are nomina 
nuda. Torrey and Gray, in 1840, described several species, 
among which was A. Hupatoria, var. mollis, afterwards 
raised to specific rank by Britton in 1892. Wallroth’s mono- 
graph of this genus, in 1842, was not recognized by any of
