In distinguishing the characters of Convolvulus and 

 Ipomcea, Linnaeus had combined differences taken from the 

 stigma with others from the corolla. But the differences 

 of the one not being uniformly conjoined with those of 

 the other, and in the corolla having no definable limit, he 

 had been repeatedly led to refer to Convolvulus plants 

 With the stigma allotted to Ipomoea, as in the present in- 

 stance. Many similar transpositions having accumulated, 

 from the attempts of succeeding botanists to conform in 

 their arrangement of species to the characters so constituted, 



the two aencra had become nearly useless in relation to
