Cacalia atriplicifolia, Cynthia Virginica, Aster acuminatus, 
Solidago bicolor, S. spithamea, (Curtis in Torr. and Gr. Fl. 
ined., a very distinct dwarf species), S. Curtisii, Torr. and Gr, 
l. c. not yet in flower, and S. glomerata, in the same state as- 
at the Grandfather Mountain; also Saxifraga leucanthemi- 
folia, Sedum telephioides, Heuchera villosa, Polypodium vul- 
gare, the dwarf var. of Hedyotis purpurea previously noticed, 
Scirpus cespitosus, and Agrostis rupestris ! which are confined 
to the rocky precipice already mentioned. The only tree is 
Abies Fraseri, a few dwarf specimens of which extend into 
the open ground of the summit; and the following are all 
the shrubs which we observed, viz.; Diervilla trifida, Men- 
ziesia globularis, Vaccinium erythrocarpum, Rhododendron 
Catawbiense, forming very dense clumps, Leiophyllum serpyl- 
lifolium, Sorbus Americana 2-4 feet high, Crategus punctata 
only a foot in height, Pyrus arbutifolia var. melanocarpa, 
Ribes rotundifolium ; and a low and much branched species 
of Alder, which Mr. Curtis proposes to call Alnus Mitchel- 
liana in honour of Professor Mitchell; but we fear it may 
Prove only a variety of what we deem the A. crispa, 
(Ait.) from the mountains of New York, New Hampshire, 
and Newfoundland, although it has more rounded leaves, 
With the lower surface nearly glabrous, except the primary 
veins ; while in the former (to which the names of A. crispa 
and A. undulata are not very appropriate.) the foliage is often, 
but not always, somewhat velvety-pubescent beneath. To 
our list must be added an apparently undescribed species of 
Vaccinium, first noticed by Mr. Constable.* We made a
