variety seems to be the more common and the North American specimens agree perfectly with those
from Siberia. Less general is the original form of such as is delineated in the above-mentioned work of
Jaccpin but the transitions between these two forms are as frequent as fl.) so that «. and (3. may be
esteemed the two extremes. Besides these, there occurs, though but rarely, another variety or rather
more vigorous state of the plant, where the incisions of the leaflets have no entire margin, but appear here
and there incised. Lastly, there exists another form, which, in regard to the leaves, holds an intermediate
rank between our var. (!. aud the P . multifida, but whose straight erect stem, peculiar pubescence, inflorescence,
&c. unite it with P . Penmyhanica.—If this species grows in a sterile dry soil, the leaves are not interruptedly
pinnated. Thus, this separation of the lesser leaflets, which, in reality, are the inferior serratures
of the larger leaflets, only takes place in consequence of a more vigorous growth. (Lehm.'t—[Dr. Torrey

allied to the foregoing, is certainly a good species. Besides the above marks, the incisions of the leaflets are
deeper narrower, not erect as in P. Pemsylvanica., but patent; the calyces are white, tomentose, and never,

the Hamburgh Botanic Garden, and both have proved constant in their form. (Lehm.)—[Dr. Richardson
having satisfactorily ascertained what is the true P. arguta of Pursh, I have taken the liberty of altering
the name which Dr. Lehmann had given to this plant, and adopting the MSS. one of Mr. Douglas. But
I must confess, the plant seems to me only a state of P. Pennsylvania with unusually deeply divided or
pectinated leaflets. H.]
