174 MR. D. OLIVER, JUN., ON THE 
proportion of the spur of the corolla ; the comparative proportions 
of the calyx-lobes, &c. The sections of A. De Candolle employed 
in the ‘ Prodromus,' of questionable utility in their general ap- 
plication, are almost useless in the apportionment of the Indian 
species. 
Finally, I may be allowed to express my conviction, that in the 
investigation of the development and general morphology of the 
* Bladder-worts, there is a wide field for extended observation ; 
and I believe that a monograph of the genus, thoroughly worked 
out in respect to these, would be, although a work of much labour 
and difficulty, a most valuable contribution to science.

racters), a pair of very small laterally disposed laminse, which І call bracteole ; 
these, in certain species, almost equal the bract in length and proportions, ex- 
cepting that in the case of those having bracts volute at the base, the bracteoles 
are, I think, not to the same extent free below their attachment. In none of 
the Indian Utricularia, however, do the bracts and bracteoles assume anything 
like the development of those of the singular section * Orchidioides’ (A. DC.), 
a South American group of the genus, in which they are relatively very long, 
attaining a length of from } to $ in.
