obtusis, integerrimis. Bractee lineari-lanceolate, integre, pedicellis bre- 
viores. Calyx 5-phyllus, sepalis acuminatis, pubescentibus. Corolla pur- 
purea, ferè 2 uncias longa, ventricosa, limbo bilabiato, labio superiore 
bilobo, inferiore trilobo, palato aperto, pubescente. Anthere lanuginose. 
Semina angulata. 
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.
