56 ESSA YS. 



subsequent " Enumeration of Saxif ragaceous Plants," it must 

 have been introduced into the English gardens by Fraser as 

 early as 1810. * We know not how such a common plant could 

 have escaped the notice of Michaux. Under the name of 

 Lettuce the leaves are eaten by the inhabitants as a salad. 

 At this same place we also saw an Umbelliferous plant not 

 yet in flower, which we believe to be Conioselinum Cana- 

 dense, Torr. & Gr. (Selinum Canadense, Michx.), a very rare 

 plant in the extreme northern States and Canada, to which 

 we had supposed it exclusively confined. We found plenty 

 of Cimicifuga Americana, Michx., but were obliged to con- 

 tent ourselves with specimens not yet in flower, and with 

 vestiges of the last year's fruit. It should be collected in 

 September. 



We were also too early in the season for Chelone Lyoni, 

 Pursh, which we found in abundance between the precipice 

 mentioned above and the summit of the mountain, with the 

 flower-buds just beginning to appear. Mr. Curtis remarks 

 that Mr. Nuttall could not have met with this exclusively 

 mountain flower near Wilmington ; and also, that the C 

 Lyoni of Pursh and the C. latifolia of Muhlenberg and 

 Elliott, are doubtless founded upon one and the same species. 

 Both, indeed, are said to have been collected by Lyon, and the 

 leaves vary from ovate-lanceolate or oval with an acute base, 

 to ovate with a rounded but scarcely cordate base. Pursh's 

 character is drawn from a cultivated specimen. Here we 

 again met with the Aconitum previously observed in similar 

 situations on the Negro Mountain, and which, being then only 

 in bud, we took for the A. uncinatum, a species collected in 

 this region by Michaux, and recently by Mr. Curtis and other 

 botanists. We were greatly surprised, therefore, to find that 



1 The only important discrepancy respects Haworth's character, " Co- 

 rolla irregularis, petalis 2 inferioribus elongatis divaricantibus graciliori- 

 bus," and " Flores albi, rubro minute punctati " ; while the petals in our 

 plant are very nearly equal and similar, and pure white, except the yellow 

 spot at the base. Aulaxis nuda, Haworth, I. c. (of unknown origin), ap- 

 pears to be the more ordinary and nearly glabrous form of this species. 

 Mr. Don's description of S. erosa, probably drawn from the cultivated 

 plant, also differs from our plant in several minor points.
