and rounded at the apex, the pairs separated by wider intervals, 
the lowest pair relatively much smaller, the interposed leaflets 
much less developed, the petiolar portion of the leafstalk longer. 
In its earlier stages the inflorescence is strikingly different from 
that of Azrsuta. In the latter the longer and stouter villous racemes 
are closely flowered and conspicuously bracteose; in s¢riafa the 
delicately slender rearly glabrous racemes are more viscid-glandu- 
lar and much less closely flowered, with minute inconspicuous 
bracts and rounded-truncate instead of pointed flower buds. 
In adopting the name s¢ria¢a for this species I have simply fol- 
lowed Dr. Gray who, having. seen Michaux’s material, cites the’ 
name as a synonym, not of A. Expatoria, but of A. Eupatoria vat. 
parviflora ot Hooker, the plant here taken up, giving to the ref- 
erence his mark of authentication. (T. & G. Fi. loc. cit.). 
3. AGRIMONIA PUMILA Muhl. 
The smallest of our species, 1°-2° high, erect or more slender | 
and assurgent, simple or with a few ascending branches from the 
lower part of the elongated terminal raceme. Stem clothed with 
loose often coarse pubescence and hirsute with spreading hairs — 
which become subappressed above and obsolete in the pubescent 
racemes. Leaves often crowded low on the stem, often trifoliate, 
small, 114’-3%4’ long, 114’-214’ wide, the upper ones much re- 
duced, Leaflets firm, 1-2 pairs, the lower pair always small, oval 
to obovate or the odd leaflet cuneate, sessile or subpetiolulate, ob- 
tuse or rounded at the apex or sometimes acute, crenate or den- 
tate or sometimes boldly crenate-dentate, commonly 1/-1 34’ long, 
dark-green above and loosely appressed-hairy to nearly smooth, 
the margins loosely appressed-ciliate, paler and softly pubescent 
below, pilose-pubescent or hairy along the veins, obscurely, if at 
all glandulose ; leafstalk villous ; subleaflets wanting or a minute 
pair, entire or few-dentate. Stipules small,the main pairs rounded 
and cordate-clasping, acutely dentate-lobed or incised, some- 
times dentate on the inner margin. Racemes loosely-flowered, 
often remotely-flowered below. Flowers small,the buds subglobose. 
Fruit small, 2” long, 1-114” wide, turbinate or subhemispheric, 
minutely glandulose, often canescent in the sinuses when young, 
the disk mostly obscurely margined and rising to the short and 
broad calycular process, the bristles loosely ascending and e 
Roots developing short tuberous thickenings. (Plate 283, fig. Be
