Agrimonia gryposepala Wallr. 



Mature fruit faintly striate, 2.5-2.8 mm in diameter, exclusive of the bristles; 



bristles in 3 or 4 rows, the longer ones 1.5-1.8 mm long; petals about 3 mm 



long, connivent, not acuminate or indurated at the tips; plants slender; root 



tuberous; lower surface of leaflets obscurely resinous-dotted. 2. A. rostellata. 



Lower surface of leaflets more or less densely pubescent, especially on the veins; 



rachis of inflorescence and petioles closely pubescent, usually with subappressed 



and spreading hairs, short glandular hairs lacking. 



Lower surface of leafllets velvety to the touch, the pubescence consisting of long, 



spreading hairs; resinous dots obscure or lacking; stipules of median leaves 



reniform, rather evenly but coarsely dentate; petals about 3 mm long 



3. A . pubescens. 



Lower surface of leaflets not velvety, the pubescence consisting of long hairs but 

 these more or less appressed; resinous dots copious and prominent; stipules 

 of median leaves ovate, long-acuminate with a few irregular teeth below; 

 petals about 3.5 mm long. (See excluded species no. 372, p. 1063.) . .A. striata. 

 Leaflets (exclusive of the small, intermediate ones) usually 11-15, lanceolate to nar- 

 rowly lance-oblong, copiously glandular beneath; fruit about 3 mm in diameter, 

 exclusive of the ring of bristles; the lower bristles widely spreading, the upper ones 



the longer; stems densely hirsute; plants of wet and moist habitats 



4. A. parviflora. 



1. Agrimonia gryposepala Wallr. Agrimony. Map 1168. More or less 

 frequent throughout the lake area. It is usually found in dry soil, but is 

 also sometimes found in moist soil, especially where the soil is of a 

 sandy nature. Since this species and the next two were formerly regarded 

 as an aggregate, all of the reports made prior to our present manuals must 

 be ignored because we do not know to which species they should be re- 

 ferred. From the specimens at hand it seems that this species is northern 

 in its distribution, while the other two are found throughout the state. 



N. B., s. N. S. and cent. Maine to Minn, and Calif., southw. to N. C, 

 Tenn., and Mo. 



2. Agrimonia rostellata Wallr. Map 1169. Found throughout the state, 

 although it is restricted to dry soil generally of thick woodland. 



Conn., cent. N. Y. to Nebr., southw. to Ga., Tenn., and Mo.
