Hab. Plains of Canada, as far north as the Saskatchawan. Mr. Goldie; Br, Richardson; Mr. Blair; 

 (in Bot. Man^.) Douglas; Dnimmond; Dr. Todd. — This most beautiful species is now cultivated in the 

 gardens of this country.

Hab. Borders of Canada, about Lake Ontario. Michaux. Islands in Lake Erie, rare. Douglas; 1823.^ 

 This plant I have never seen. Nuttall doubts if it be distinct from P. pauciflora ; but then it must be 

 incorrectly described by Michaux, who says that the keel is not crested, and that the flowers are solitary and 

 scattered. De Candolle has only seen a specimen without inflorescence.

Hab. Bay of Eschscholtz. Chamisso. Kotzebue's Sound, in the same Bay. Laj/ and Collie in Capt. 

 Beechey^s Collection. — This is probably the only species of Dianthus that is realiy a native of North 

 America, and which shows the affinity of the vegetation of the North -West Coast with that of Siberia in the 

 same latitude, where the present species was originally discovered. D, Armeria^ enumerated in the Floras 

 of the United States, is allowed by all to be introduced, and the D. carolinianus of Walter is a very dubious 

 plant, ^vith which no one seems to have been acquainted but Walter himself. Neither Capt. Beechey's 

 specimens of D. repms^ nor those communicated to me by Chamisso, nor the individuals in Willdenow's 

 own Herbarium, according to the last mentioned author, possess a creeping root: on the contrary, one 

 which descends deep into the earth, and bears on its summit many stems.
