In distinguishing the characters of Convoryuius and 
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 Convoxvurus plants 
with the stigma allotted to Iromaa, 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 thé characters so constituted, 
the two genera had become nearly useless in relation to 
each other. But Jacquin, in his late reform of their cha- 
racters, has relied singly upon the difference of the stigmas; 
and no dislocation seems to be thence inferred in the natural 
connexion of the species that could have been avoided by 
more complex combinations, as the species are now found
