I have found it impossible to mark by any certain characters the 

 limits which separate the genus Convolvulus from the Ipomaa. A"e 

 transition from the globose, undivided stigma, to the "eeplv clo>c 

 style, is so gradual in different species, as to render it difncuii i 

 determine the termination of one genus, and the commencement o 

 the other. If we confine the Convolvulus to those plants which n.i^^e 

 oblong, thickened stigmas, all of our species must be trausferre 



^I have for the present transferred to the Ipomcea all the 8peci« 

 with sti'^mas undivided, although sometimes furrowed, and retain 

 in Convolvulus those with two Sistinct stigmas. This arra"f^:".^J;: 

 -which is by no means satisfactory, has caused the removal oi i • * 

 Difolia and macrorhiza to Convolvulus; and of C. Car^iinus to if 



vncea*
