BOTANICAL EXCURSION TO NORTH CAROLINA. 28 
this direction, after exploring some of the higher mountains 
in the neighborhood, he retraced his steps to the Savannah 
River, proceeding thence through Georgia and Alabama to 
Mobile. His well-known and very interesting volume of 
travels! contains numerous observations upon the botany of 
these regions, with occasional popular descriptions, and in a 
few cases Latin characters of some remarkable plants ; as, 
for example, the Rhododendron punctatum (which he ealls 
R. ferrugineum), Stuartia pentagyna (under the name of 
S. montana), Azalea calendulacea (which he terms A. flam- 
mea), Trautvetteria, which he took for a new species of 
Hydrastris, Magnolia auriculata, ete. He also notices the 
remarkable intermixture of the vegetation of the north and 
south, which occurs in this portion of the mountains where 
Halesia, Styrax, Stuartia, and Gelseminum (although the lat- 
ter “is killed by a very slight frost in the open air in Penn- 
sylvania”) are seen flourishing by the side of Birches, 
Maples, and Firs of Canada. 
I should next mention the name of André Michaux, who 
at an early period, amid difficulties and privations of which 
few can now form an adequate conception, explored our coun- 
try from Hudson’s Bay to Florida, and westward to the Mis- 
sissippl, more extensively than any subsequent botanist. A 
few of his plants have not yet been rediscovered, and a con- 
siderable number remain among the rarest and least known 
species of the United States; it may therefore be useful to 
give a particular account of his peregrinations, especially 
through the mountain region which he so diligently explored, 
and in which he made such important discoveries. or this 
purpose I am fortunately supplied with sufficient materials, 
having had the opportunity of consulting the original journals 
of Michaux, presented by his son to the American Philosoph- 
ical Society. I am indebted for this privilege to the kind- 
ness of John Vaughn, Esq., the secretary of the society, who 
directed my attention to these manuscripts, and permitted me
