from it. I think there can be no doubt, however, that the two 
species are distinct and that a comparative study of growing 
Plants would disclose more pronounced differences than dried 
specimens have revealed, The uniformly small size and simple 
or nearly simple habit of pumila and its slender and elongated 
loosely-flowered raceme are usually sufficient to distinguish it. 
The pubescence seems to be generally coarser and more hirsute 
than in mollis, and the much smaller, mostly trifoliate leaves more 
crowded on the lower part of the stem and apparently of thicker 
texture. I have not seen satisfactory material in mature fruit. 
The range of the plant is clearly more restricted northward than 
that of mollis, and more extended southward as far asat pres- 
ent known. 
I adopt Muhlenberg’s name pumila for this species with some 
hesitation and only to avoid the alternative of conferring a new 
name. Muhlenberg characterized his plant by the one word “little” 
and gave its habitat as Mississippi. Applying the rule of exclu- 
Sion it would appear that only this species could have been in- 
tended. If it should be found that A. mollis extends into Missis- 
Sippi the name would have only a dubious claim to availability. 
4. AGRIMONIA MOLLIS (T. & G.) Britton. 
Not aromatic and obscurely if at all glandulose, mostly slender 
and 2°-3° high (1° to over 6°), the branches ascending or some- 
times spreading, either few and simple or forming a loose panicle 
which exceptionally attains a spread of as much as 2°-3°. Stem 
below loosely tomentose-pubescent and weakly villose with spread- 
Ing or subspreading hairs, becoming finely hoary-tomentose or 
Subappressed pubescent above and in the racemes. Leaves rather 
dark green, 3/-12’ long, 2/-7’ wide, a common size being 5’ or 6 
by 3’ or 4’. Leaflets commonly 2 or 3 loosely separated pairs 
(1-4 pairs), mostly obovate-oblong, varying from obovate to ellip- 
tic, subsessile, rounded or somewhat acute at apex, dentate-serrate 
to crenate, the odd leaflet mostly obovate, often on a foliolate 
Stalk, reaching an extreme size of 414’ X 2’, the largest lateral leaf- 
lets becoming 3/ X I 14’; upper surface sparsely hirtellous-pubescent 
and roughish to glabrate, the margins finely subappressed-ciliate, 
lower surface paler and minutely downy to velvety-pubescent ; 
leafstalk finely pubescent and somewhat tomentose-villose. Stip- 
ules varying from small, lanceolate and entire on the lower leaves 
and in dwarf plants to cordate-clasping with cut-serrate or incised
