Hab. On the North-West coast of America. Merit, (ex Pursh.)—With this species I am unaquainted.
Though given as a native of Kamtschatka, it is not noticed by Chamisso among the Rosacea of that country
described in the Linnaea, nor does it exist in Capt. Beechey’s Collection.

accessoriis imisque nanis indivisis, caule unifloro subdiphyllo, petalorum venis omnibus dis-

Hab. Island of Unalaschka. Chamisso.—No specific character appears to have been any where given of
this plant. But Chamisso says it differs principally from S. Rossii, to which it is too nearly allied, by its
hairiness.
4. S. glacialis; tota villo denso flavicante vestita, foliis pinnatis, pinnis ovato-oblongis
summis imisque minimis, mediis majoribus subunidentatis, flore magno unico terminali,

allied to S. Pechii, (Bot. Mag. t. 2863,) which has not hitherto been found beyond the limits of the United
States; but this latter plant is of humbler growth, with a less leafy stem, and the terminal pinna of its
radical leaf is truncate at the base.
