uniformly perfect, as, indeed, they are figured by De Lessert, 
although De Candolle has otherwise described them. It isa 
slender, delicate plant, from eight to twelve, or rarely ex- 
ceeding eighteen inches in height, with pure white flowers. 
During this ascent, we collected Galium latifolium, (Michz.), 
just coming into flower; and we subsequently found this 
species so widely diffused throughout the mountains of North 
Carolina, that we were much surprised at its remaining so 
little known since the time of Michaux. On a moist rocky 
bank by the road-side, we gathered some specimens of a 
Scutellaria, which did not again occur to us. It proves to be 
a species méntioned by Mr. Bentham under S. serrata, and 
subsequently described by Dr. Riddell with the name of 
. saxatilis,* which apparently is not of uncommon occur- 
rence westward of the Alleghany Mountains. It is a slender 
plant, from six to twenty inches high, and the stems often 
produce slender subterranean runners, from their base. We 
here also collected Asarum Virginicum, (Linn.) in similar si- 
tuations. In the higher mountains the northern A. Cana- . 
dense takes the place of the former species, while A. arifolium, 
laxe corymbosis, filamentis clavatis, antheris ellipticis muticis, carpellis 
(5-10) stipitatis stellatim patentibus clavato-lunulatis compressis leviter
