of certain Genera in the Flora Peruviana, 241 



Ob8. a Nicotiana calycis laciniis foliaceis tantum difFert. Salpiglosis so- 

 lummodo distin^uitur corolla irregulari subbilabiata et calycis nori limbo fo- 

 liaceo. Sectiones Nicotianae potiiis qukm divefsa genera viduntur. 



A careful examination of the various species of Nieremhergia 

 and Petunia, which have fallen under my notice, has led me to 

 the conclusion that they constitute but one genus, which is 

 scarcely of itself to be distinguished from Nicotiana, except by 

 the foliaceous segments of its calyx. The tube of the corolla is 

 found to be more or less dilated in different species, but this 

 character cannot be regarded as of more than specific import- 

 ance. The Nicotiana minima of Molina is identical with Nie- 

 remhergia repens. Salpiglossis agrees with Nicotiana in the 

 structure of its calyx, and is only distinguished from it and 

 Nieremhergia by its somewhat irregular corolla.
