Species. 1. WV. Tabacum. Cultivated. No where de- 
cidedly indigenous. Introduced into North America ap- 
parently by the aborigines. Near the confluence of Pid- 
* geon river with the Tennessee, and in some other parts 
of the state of Tennessee, I am assured by the earliest 
settlers, that Tobacco came up spontaneous around the 
: _ ruins of the ancient aboriginal stations. The genuine ha- 
— ~~ bitat of the Wicotiana Tabacum, though so confidently re- 
ferred to America, still appears to be involved in obscu- 
_ rity; in Europe it was first made known about the year 
_ 1560 by Nicot, a French ambassador, who had received 
seeds of it from Florida during his residence at Lisbon, 
nd it was in honour of him that the genus acquired its 
name; about the same time also the Spaniards received it 
_ from Tobaco, a province of Yucatan, hence its common 
5; name. ‘The learned Savary, however, asserts that the 
Persians have cultivated Tobacco (now) more than 400 
—-s-years, and that they received it from Egypt. 2. rustica, 
-... According to the observations of the late Dr. B. S. Bar- 
ton, cultivated and introduced by the indigenes. Still na- 
-_turalized near the borders of some of the smaller lakes in 
the western parts of the state ef New York. Cultivated
