Hab. Newfoundland, (Dr. Morrison,) and throu-lioiit Canada, as for as the Slave Lake, iu lit. 62^.^ 

 What I here call F. Virginiana is the same as I have received from Dr. Torrey under that nara^; but I 

 must observe that I do not see how it is to be distinguished from the F. elatior of Ehrh. and Smith. It 

 does not appear to me that any dependence can be placed on the direction of the hairs of the p.-tiol.s uud 

 peduncles. 1 find them often variable on the same plant. If Smith's F. Vinjlniunu (iu Uees' Cyd.) be tlio 

 true species, with the hairs of the petioles and peduncles erect, there aie only two or tbioe specimens in th« 

 whole Collection which have that character, and those were found iu the most northern latitudes. The others 

 accord in almost every particuhir with the F. elatior of Smith. 



3. F. Canadensis; "major; foliolis amplo-ovalibus, lutcralibus nianifciite pctiolutis: 

 pedicellis longis, recurvo-pendulis : receptaculis seminuni globosis, fnvoso-scr()I)iculatis, 

 villosis." Mich. Am. v. \. p. 299. Rich, in Franld. UtJouru. ed. 2. App, p. 20. De Cavd.

Hab. Woods and hilly places, from Hudson's Bay to the United States. Michaux. Woody country 

 between lat. 32° and 64^, north. Dr. Richardson (in Frankl. Ut Journ.)— This beinjf the only Fragaria 

 described as a native of Canadii, it was natural that Dr. Richardson sbould refer Iiis specimens to it In 

 this he has done con-ectly; but the species is probably not different from the F. Virgimn7Ui. Smith 

 does not notice Michaux's plant. Torrey unites it, without hesitation, to F. Virfjiniana. To me it appears 

 that the two may reasonably be considered as one species ; and may not this be the origin of our F. elatior? 

 which Miller declares to be a native of America. 



4. F. Chilensis; floribus (magnis) patentibus, foliolis late olwvatis obtusis.simis grosse 

 serratis coriaceis rugosis subtus sericeo-villosissiniis, pedunculis calycibusque sericeis. — EkrL

Hab. North-West coast of America, throughout Cahfomia, and from Puget Sound to " Point Bodugo," 

 common along the shores. Douglas^ Dr. Scouler.—l have the same species gathered by Mr. Ma<rae in 

 Chili, and Mr. Douglas has seen it also in Juan Fernandez. — Tliis very distinct species of Frngnria srems 

 to occupy a great extent of coast on the Pacific. In the really vnlA stite, the flowers are very large, and the 

 under-side of the leaves, as well as calyx and peduncles, are clothed \\\Xh copious long hllhy hairs. Wliether 

 my var. /3. which exists in Dr. Scouler's collection, be a cultivated speooDeu at Fort Vancouver, or wht'tbcr 

 its appearance arises from luxuriance of soil, I know not ; but it is four times the size of the usual state of the 

 wild plant, less silky, and with numerous flowers upon the tall panicles. In drying, the whole turns almost 

 black, owing to its succulent nature, when recent.

* For the determination of the individuals of this g-enus, and the characters and descriptions of the new species, 

 I am indebted to my valued friend Professor Lelimann of Hnnihurgh, the leanu'il autboT of " Monographiit Generii 

 Potentillarum." These new species have already ap])('ared Jn the " Stirpium ab J. G- C Lehmann, primum dt'scrij*-
