SHORT ON WESTERN BOTANY. 103 



but a few proofs out of many which might be cited. In 

 speaking of the seduin piisillum, Michaux mentions it as being 

 found in North Carolina, at a place called " The Flat-Rock." 

 Pursh, the author of another and later work on American 

 Botany which we sliali presently mention, in describing (he 

 same plant after Michaux, but without his precise accuracy, 

 says, that it is met with "on flat rocks in Nortli Carolina" 

 and elsewhere. Now, although this little latitude in the 

 most of instances might safely I)e indulged in, as similar 

 plants are for the most part found in similar localities in the 

 same countries, yet in the present instance it has proved 

 unfavourable to Pursh ; for Mr Nuttall, of whom we shall 

 hereafter speak more particularly, writing to us some years 

 ago, on the subject of this particular plant, and its peculiar 

 and restricted locality, thus expresses himself. " On this 

 singular rock of granite of nearly five acres area, I had for the 

 first time, during my numerous peregrinations in the United 

 States, the satisfaction of meeting with this extremely rare plant, 

 and upon the same rock whei-e so long before the unfortu- 

 nate Andre Michaux had found it ; from that time to the 

 present no one except Michaux and myself had ever collected 

 or met with it — it has never yet been any where found, but 

 on the « Flat-Rock,' near Camden, in North Carolina." 

 The Bellts integrifoUo, or American daisy, first described by 

 Michaux in the work now noticed, the existence of which 

 Was even questioned by some American Botanists, has since 

 been found abundantly in Kentucky and Arkansas. And it 

 has been our good fortune to detect the original Cimila gla- 

 bella of this author, in the neighbourhood of Lexington, 

 though long confounded with a totally distinct species grow- 

 ing around the falls of Niagara. 



Besides the Flora Boreali- Americana and the volume on 

 American Oaks by the elder Michaux, we are indebted to the 

 younger for a splendid work on the forest trees of our country, 

 the Si/ha Americana, forming with the Oaks, three large vol- 

 unies, with beautiful and highly accurate coloured engravings. 

 Of this work, which should be in the library of every intelli-
