Hab. Frequent upon tlie Rocky Mountains between latitudes 52° and 06°, Drummond, — This entirely 

 agrees with our Europnean specimens of this plant, and we have, under the preceding species, mentioned how 

 difficult it is to distinguish the two.

ILvB. Behring's Straits. A. MenzieSj Esq. — This species differs considerably from any with which we 

 are acf^uainted. Its inflorescence a good deal resembles that of S, kypnoideny but its foliage is quite peculiar, 

 being extremely harsh and rigid, shining^ as if varnished, and at the same time sparingly clothed with 

 apparently viscid hairs. We had called this S. veiiiicosa in our own manuscript, but having received speci- 

 mens of the single-flowered state under the name of S. sileniflora^ we gladly adopt the name, though it does 

 not appear to be any where published. It has indeed been referred incorrectly, in the Botany of Captain 

 Beechey's Voyage, to S. ccespitosa.
