4 BOTANICAL EXCURSION TO 
of Mimosa Julibrissin, propagated from a tree which his 
father had brought from Europe. From this stock, probably, 
the latter has been disseminated throughout the Southern 
States, and is beginning to be naturalized in many places. 
I have no means of ascertaining what portions of the 
country Michaux had visited previously to April 1787, when 
he set out from Charleston on his first journey to the Alle- 
ghany Mountains, by way of Savannah, ascending the river 
of that name to its springs in the Cherokee country, and 
following very nearly the route taken by Bartram eleven 
years before.* He reached the sources of the Theowee River 
on the l4th of June, and was conducted by the Indians 
across thé mountains to the head of the Tugaloo (the other 
principal branch of the Savannah), and thence to the waters 
of the Tennessee. After suffering much inconvenience from 
unfavourable weather and the want of food, he returned to the 
Itídian village of Seneca by way of Cane Creek, and descend- 
ing along the Savannah to Augusta, arrived at Charleston on 
the Ist of July. His notes, in this, as well as subsequent 
journeys to the mountains, often contain remarks upon the 
more interesting plants he discovered; and in some cases 
their localities are so carefully specified, that they might still 
be sought with confidence. On the 16th of July, he embarked 
for Philidelphia, which he reached on the 27th; and after 
visiting Mr. Bartram, travelled to New York, arriving at the 
TR he had established in New Jersey, about the Ist of 
August. Returning by water to Charleston the same month, 
he remained in that vicinity until February, 1788, when he 
embarked for St. Augustine, and was busily occupied, during 
this spring, in exploring East Florida. His journal mentions : 
* In this journey he was accompanied by his son, who shortly after- 
wards returned to Europe. Before they reached Augusta, their horses 
were Gest a misfortune, as it appears from Michaux's remarks, of no 
uncommon occurrence in those days; and they were obliged to pursue 
ure. journey to that place on foot. On the way, he discovered “@ 
shrubby Rumex” which he terms Lapathum occidentale ; doubtless the — 
Polygonella parvifolia of his Flora, and also the Polygonum polygamum 
of Ventenat.
