Native. Septal, &c. This is a species which I do not 

 well know, and much fear that it is in fact made up from 

 several species or varieties, which, when their styles are 

 distinct, pass under other names. I cannot decidedly 

 assert the fact, but I have seen some grounds for supposing 

 that the elongated and united styles are simply a deviation 

 from the ordinary condition of the parts, which occurs oc- 

 casionally both in canina and tomentosa ; and if so, the 

 Rosa systyla of English authors may be no more a real 

 species than is the Bidens Coreopsis or the Linaria 

 Peloria.
