as far as Yancey County. Several new species were 

 detected by this gentleman and j^ublislied in vol. xlv 

 of Silliman's Journal. Since the above date he has 

 made several visits to the same region. 



Mr. RuGEL, a German collector of plants, spent 

 some time in our mountains in 1842. His discov- 

 eries were published by Shuttleworth and others. 



Mr. Dow, a young Botanist, traversed the whole 

 length of our mountain range in 1844, but I have 

 never learned if his observations and discoveries 

 have been made public. 



The writer of this, during a residence near the 

 mountains in 1835-36, had occasional opportunities 

 of visiting the high ranges in Burke and Yancey, as 

 also the counties of Lincoln, Mecklenburg, and Cald- 

 well. In 1839 he spent the summer in traversing 

 the mountains from Ashe to Georgia. A visit of a 

 few weeks was again made to Ashe and Yancey in 

 1845 ; and another in 1854 to Buncombe and Hen- 

 derson. Besides these, a residence of some 3-ears in 

 various portions of the middle and lower sections of 

 the State, comprising in all about twenty years, has 

 given him opportunities of becoming acquainted with 

 the vegetable productions of the State, of Avhich he 

 has assiduousl}'- availed himself, and the results have 

 been published in various journals in tliis country 

 and England. The accompanying list of species con- 

 tains all that is known of the plants of North Caro- 

 lina, — a longer list than has yet been published of 

 any State in the Union.
