Hab. North America. Banks. Herb, {in De Cand.) Sandy banks formed by the floods in the rivers 

 among- the Rocky Mountains, betiveen lat. 52° and 56°. Dmmmond, — Numerous specimens of this pretty 

 Parnassia exist in Mr. Drummond's portion of the collection, and all so constant to their characters, that I 

 have little hesitation in considering- it a good species, and I think too it is the P. parvijiora of De CandoUe, 

 It is remarkable for its slenderncss, for the root-leaves being ovate, that of the stem still narrower, and so 

 small as, in most instances, to represent a true bractea. Whether the P. ovata jS. Belvisii of De Caudolle, 

 should be considered the same, as I rather suspect, or not, I have no materials for detorminiug. The flower 

 of our pjant is considerably smaller than that of P. palustris, so as well to merit the name of parvijiora.

Hab. About Quebec, Mrs. Pcrcival, and Lake Huron, Dr. Todd: which are perhaps the most northern 

 limits of this fine plant, as well as the most western, at least in that latitude. — The leaves are more coria- 

 ceous, and paler beneath than any other species with which I am acquainted : their shape is either broadly 

 ovate or elliptical ; but they may vary in form, and I suspect the P. grandifoUa of Beauvois and De Candolle 

 can hardly be considered diflferent. The P. asartfulia of Ventenat I have never seen, nor do the American 

 Botanists themselves appear to be acquainted with it. 



4. P. Kotzehiiei ; squamis setis tribus gracilibus, foliis radicalibus caulinoque (si adsit)

 was also found by Messrs. Lay and Collie in Capt. Beechey's Expediiion. Rocky Mountains, between kit, 

 52° and 5G°, Dnmmond. Bear Lake, and thence to the shores of the Arctic Sea. Dr. Richardson. — I am
