 with Sternberg's iigm'e and description.

Ruj. Behring's Straits. Mr. Menzies, "Height of Land" upon the Eocky Mountains, on the West 

 sides, near the sources of the Columbia. Drummond.—Thai the present highly cuiious and interesting plant 

 is the Saxifraga pectinata of Pursh, we have no reason to doubt, since it not only agrees sufficiently well with 

 his description, but our specimens from Mr. Menzies are from the same station. A slight examination of 

 tlie flower and fruit, however, avUI satisfy any one that, notwithstanding the habit and foliage hear a consid- 

 erable resemblance to an extensive group of true Saxifrages, it can nevertheless not possibly rank with that 

 genus. 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 thein in an oblique direction from sinus to
