 — This exactly corresponds with specimens I possess from the " Bluffs" of the Missoui'i, gathered by jMt. 

 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 consef|ueiice 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 Umbellifer- 

 ous plant, described by Dr. Toney in the " Plants of the Rocky Mountains," (p. 207,) is very nearly aUied 

 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, seg- 

 mentis 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. 



4. F.f Canadensis; " foliorum segmentis ramosis lucidis linearibus." — Linn. Sp. PL p, 

 174. De Cand. Prodr. v. 4. p. 174. 



Hab. Canada. Linnceus. — 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
