Messrs. Lay and Collie in Beechey’s Voyage.—It is observed in the Linnsean 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. Don farther observes, that Pursh, who 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 large and yellow. Dr. Adams found it upon the Caucasian
Alps; and both in Baffin’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 latitude
far south of the sources of the Columbia. We find a remarkable difference between our Arctic Seashore
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-partite calyx; and
appearing to correspond in almost very particular with the European state of the plant, as far as can be
judged by the figure of Sternberg; still we have only considered the two as varieties.

Hab. Behring’s Straits. Mr. Menzies. " Height of Land” upon the Rocky Mountains, on the West
sides, near the sources of the Columbia. Dmmmond.—That the present highly curious and interesting plant
is the Saxifraga pectinata of Pursh, we have no reason to doubt, since itnot only agrees sufficiently well with
his description, but our specimens from Mr. Menzies are from the same station. A slight examination of
the flower and fruit, however, will satisfy any one that, notwithstanding the habit and foliage bear a considerable
resemblance to an extensive group of true Saxifrages, it can nevertheless not possibly rank with that
g'enus. Even the foliage has some remarkable peculiarities: the texture is extremely rigid, opaque and
coriaceous, but not thick, plane on both sides, except that the slender nerve, which is pellucid when the leaf is
held up between the eye and the light, is slightly channelled on the upper side; nor does the nerve pass
through the centre of the segments at their bases, but traverses them in an oblique direction from sinus to
