from the former.” But if this species be the Robertsonia 
micranthifolia of Haworth’s Succulent Plants, as is most 
probable, and consequently the Aulaxis micranthifolia of this 
author’s subsequent enumeration of Saxifragaceous Plants, it 
must have been introduced into the English gardens by 
Fraser, so early as 1810.* We know not how such a com- 
mon plant could have escaped the notice of Michaux. Under 
the name of Lettuce, its leaves are eaten by the inhabitants 
asa salad. At this place we also saw an umbelliferous plant, 
not yet in flower, which we believe to be Conioselinum . Cana- 
dense, Torr. & Gray (Selinum Canadense, Michaux), which 
is very rare in the extreme Northern States and Canada, to 
Which we had supposed it exclusively confined. We found 
plenty of Cimicifuga Americana (Michaux), but were obliged 
to content ourselves with specimens not yet in bloom, 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 growing plentifully between the 
precipice mentioned above and the summit of the mountain, 
With its flower-buds just beginning to appear. Mr. Curtis 
remarks that Mr. Nuttall could not have met with this 
exclusively mountain plant near Wilmington; and also that 
the C. Lyoni of Pursh, and the C. latifolia of Muhlenberg 
and Elliott, are doubtless founded on one and the same 
species. Both, indeed, are said to have been collected by 
Lyon, and the leaves vary from oyato-lanceolate, or oval
