—This exactly corresponds with specimens I possess from the “ Bluffs” of the Missouri, gathered by Mr.
Bradbury. The peduncles sometimes arise from the root, more frequently from a short stem: the flowers
are yellow in some specimens, in others white, perhaps the consequence of drying.

Hab. Plains of the Columbia River. M. Lewis. Banks of streams, among stones, at the “ Great Falls”
of the same River. Douglas.—If I am correct in referring Mr. Douglas’ specimens to the present species, it
is a smaller plant than the preceding, quite glabrous, with shorter segments to the leaves. The root is
fusiform, and the whole plant has a good deal the odour of Fennel, but is more aromatic. The Umbelliferous
plant, described by Dr. Torrey in the “ Plants of the Rocky Mountains,” (p. 207,). is very nearly allied
to the present, but smaller, and with less compound leaves. Is is hardly possible to determine accurately
the Genera of either in the absence of fruit.
3. F. ? Palmella; glabra subacaulis, foliis bipinnatifidis sublonge petiolatis glaucis, segmentis
linearibus obtusiusculis inferioribus non raro iterum pinnatifidis, pedunculo foliis
subbreviores, involucro nullo, involucello unilaterali dimidiato palmato disco florifero.
Hab. About Carlton House, on the Saskatchawan. Drummond.—I possess the same species from the
Missouri, gathered by Mr. Bradbury. The root is large, thick, subfusiform. The whole plant not more
than a span high, glaucous. Petioles long and slender. The involucels are very remarkable, truly palmate,
gradually tapering into a broad petiole or ray, and bearing the small umbellulse of white flowers on the
disk. The immature fruit appears to be that of a Ferula.

Hab. Canada. Linncms.—This plant, whatever it may be, seems wholly unknown to recent Botanists.
—Two other Umbelliferous plants, allied to the above, and probably referable to Ferula, are in the collection
of Mr. Douglas, from the Columbia, but in too imperfect a state to enable me to refer them satisfactorily to
this or any other Genus.
