Racemes and lower surface of the leaves closely or softly pubescent. 
Roots tuberous ; stems pubescent ; leaflets not glandular-dotted beneath. 
Small or simple, with elongated terminal raceme, leaflets 3-5. 
3. A. pumila, 
Larger, branched, leaflets 5-11. 4. A. mollis. 
Roots not tuberous ; stems hirsute ; leaflets glandular-dotted beneath. 
Leaflets 5-9, oblong or rhomboid; fruit large, the bristles connivent, 
5. A. Brittoniana., 
Leaflets 9-23, lanceolate ; fruit small, the bristles radiate. 
6. A. parviflora, 
Leaflets incised with few salient teeth. 7. A. incisa. 
1. AGRIMONIA HIRSUTA (Muhl.). 
Commonly 3°-4° tall (2°-6°), simple, to loosely wide 
branched above, minutely glandulose and somewhat viscid on 
_ the branches, aromatic. Stem usually zig-zag from leaf to 
leaf, villous-hirsute with slender spreading hairs. Leaves bright 
green, large, 4’-12’ long, 3/—8’ wide, the villous leaf-stalks usually 
with short petiolar portion. Leaflets large, rather thin, commonly 
three pairs (2-4 pairs), elliptic, broadly oblong or obovate-oblong, 
_ acute, sessile or subsessile, often with rounded or subcordate base, 
the odd leaflet short-stalked or subsessile with narrowed base, 
Coarsely serrate with acute or somewhat rounded mucronulate teeth, 
the margins ciliate-fringed, upper surface glabrous or with short, 
scattered, appressed hairs, lower surface minutely, often sparsely, 
Pulverulent-glandulose and with scattered hairs on the larger 
nerves, rarely subpubescent. A frequent size of the leaflets is 
abo ut 2144/%X 1 1’,an extremesize 5’ X 3’. Interposed leaflets nor- 
mally three pairs in the distal interspace, fewer or smaller in the 
lower interspaces, the middle pair much the largest, ovate or ob- 
Ovate from a broad base, acutely lobed, often subopposite, in weak 
plants sometimes much reduced, rarely to a small entire pair. 
Stipules normally very large, sometimes over an inch broad, the 
Pairs cordate-amplexicaule, often overlapping around the stem, 
Openly cut-serrate or dentate-lobed in the rounded outer margin 
which is abruptly contracted into the ovate-acuminate incurved 
terminal lobe. In reduced plants the stipules are smaller and nar- 
Tower, the lowermost sometimes entire. Branches openly com- 
pound, widely spreading or loosely ascending, bearing spread- 
ing racemes. Racemes commonly under a foot in length (4’— 
16’), often inclined in fruit, minutely pulverulent-glandular and 
thinly spreading-villose, somewhat closely many-flowered or 
the lower flowers distant on slender ascending pedicels 2/5” 
long, the uppermost sometimes subverticillate clustered. Bracts 
relatively large, the narrow lobes ciliate-fringed, often exceed-— 
ing the flowers at anthesis; bracteoles lanceolate-attenuate, nar-
