exalbuminous seeds, besides which the two latter have an unilocular 
ovarium, with an unilocular, or spuriously 2-4-locular fruit. The 
above characters, although not always very easy to ascertain, appear, 
nevertheless, to be decided and constant, they are, moreover, accom- 
panied usually by differences in habit and other minor characters ;

amongst Scrophularinew, I have only observed in a slight de- 
in some Calceolarie ; and these have the regularly bilocular 
ovarium and fruit of the latter order. Any er details, however, 
respecting the character and affinities of Gesnerez are rendered use- 
by the elaborate exposition by Martius, in his Nova Genera et 
Bignoniacee are frequently arborescent, which is very rarely the 
case amongst Scrophularinee ; the same thing may be said of their 
pinnate leaves, long capsules, and winged seeds, but as each of these
