2 BOTANICAL EXCURSION TO 
of 1776. In this journey, he ascended the Seneca or Theowee 
river, one of the principal sources of the Savannah, and 
crossing the mountains which divide its waters from those of 
the Tennessee, he continued his travels along the course of 
the latter to the borders of the present state of Tennessee. 
Finding that his researches could not be safely extended in 
that direction, after exploring some of the higher mountains 
in the neighbourhood, he retraced his steps to the Savannah 
river, proceeding thence through Georgia and Alabama to 
obile. 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 calls 
R. ferrugineum), Stuartia pentagyna (under the name of 5. 
montana), Azalea calendulacea (which he terms 4. flammea), 
Trautvetteria, which he took for a new species of Hydrastis, 
Magnolia auriculata, &c. 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 Gelsemiumt (although the latter is 
killed by a very slight frost in the open air in Pennsylvania), | 
are seen flourishing by the side of the birches, maples, and | 
firs of Canada. 
I should next mention the name of André Micnavx, who; 
at an early period, amidst difficulties and privations of which | 
few can now form an adequate conception, explored our 
country from Hudson's Bay to Florida, and westward to the 
Mississippi, more extensively than any subsequent botanist.

Florida, the Cherokee country, &c.;" by William Bartram. Phila- ` 
delphia, 1791. 
+ Dr. Torrey has directed my attention to an unaccountable mistake 
into which the learned Endlicher must have fallen, in describing the fruit 2 
of Gelsemium, particularly in the Supplement to his Genera Plantarum 
(p. 1396), where it is established as a new tribe of Apocynacee, and 8 ` 
fruit of two follicles, as well as comose seeds, attributed to it! So faras 
they extend, the characters given by Jussieu and Richard are correct.
