 Messrs. Lay and Collie in Beechey's Voyage.—li is observed in the Liuiia^au Transactions * that this 

 most remarkable plant was first discovered, according to Mr. Don, at Cape Newnham, on the North- 

 West coast of America, by Mr. Nelson, during Captain Cook's third voyage; and his specimens still 

 exist in the Banksian Collection. Mr. Bon farther observes, that Pursh, ^vlio named the plant setigera after 

 those individuals, is wrong in stating the flower to be small and white, which is indeed quite at variance 

 with the true character, for the blossoms are hirge and yellow. Dr. Adams found it upon the Caucasian 

 Alps; and both in BaflBn's Bay and in Melville Island this species is tolerably abundant ; and so familiar was 

 its appearance to the sailors of those expeditions, that they gave it the very appropriate name of Spider 

 Plant. Upon the Rocky Mountains it has probably an extensive range, as Dr. James met with it in a lati- 

 tude far south of the soiu-ces of the Columbia. We find a remarkable difference between our Arctic Sea- 

 shore and Island specimens, and those from the Rocky Mountains of the interior; the former having almost 

 universally a single-flowered stem, an ovary partly inferior and broad calycine segments; while the latter 

 have several flowers on the stem, a free ovary, and narrow sepals or at least a deeply 5-partlte calyx ; and 

 appearing to correspond in almost very particular with the Europaean state of the plant, as far as can be 

 judged by the figure of Sternberg ; still we have only considered the two as varieties.
