Mr. Douglas considers this a species of Chelone ; and it 

 doubtless approaches that genus in the structure of its 

 anthers, and very much agrees with the plant already 

 figured in this work under the name of C. nemorosa : 

 but we have already stated that species to be a very 

 doubtful Chelone ; and this we consider still more so. It 

 is distinguished from Chelone by the form of the palate of 

 the flower, and by its angular seeds, — circumstances which, 

 taken together, are doubtless of more value than the single 

 peculiarity of the anthers. 



A native of the Kettle Falls of the Columbia, where it 

 was found by Mr. Douglas. In its native country it is 

 half shrubby, and would be the same with us in warm 

 situations : it is, however, best considered as a perennial.
