Linnjeus, who never faw the flowers of this plant, hefitated 

 whether he fhould unite it with Podophyllum or Sangui- 

 naria. Michaux, Barton, and Wm.Bartram, were pro- 

 bably the firfl: Botanifts who examined it whilft in flower ; and 

 they all agreed in confidering it as a genus diftinct from, though 

 nearly allied to, both thefe genera. Dr. Barton impofed on it 

 the name of Jeffersonia, adopted by Michau x in his Flora 

 of North-America, and by Persoon in his Synopfis. And as this 

 feparation appears to us to be required by the Itruflure of the 

 feed-vefiel, we can do no other than follow thefe authors;
