 Michaux. It has probably not been seen since Michaux's time, 

 unless perhaps by Schweinitz, until it was detected last year 

 (1841) by Dr. C. L. Hunter on the ridge of land which divides 

 the forks of the Catawba in Lincoln County, and is but a few 

 miles from Mecklenburg, where Michaux discovered it- I have 

 the past season found it near my residence, (Hillsborough, N. C.) 

 growing on rocky wooded hills.
