before the corolla has forced upon the calyx. Towards the 
apex of the ovary it presents on either face a bulging along 
the central line (a. Pl. 39.—Fig. 7.) which is transparent. 
This structure which exists in a species of Bignonia allied 
to, or the same as B. suberosa, Roxb. shews perhaps that 
the structure of Eccremocarpus is the typical structure of 
the family. If the placental septum, however, be really 
compound, as the transparent line would indicate, I should 
consider the structure as analogous to that of some Cyrtan- 
dracez, the ovula being limited to the outermost part of the 
lamelliform placenta. The opaque part of the septum appears 
a direct continuation of the placentz. It is a representation 
of cruciferous fruit with the exception of being dicarpellar. 
I very much doubt the propriety of making this a distinct 
genus, it has the fruit of Spathodea, which is itself scarcely 
distinct, and other species of Bignonia are extremely like 
this.
