The most remarkable characters of this plant, and which separate it from 

 all other known genera of Bignoniacece, consist in its regular symmetrical 

 flowers, having an unusual number both of divisions and stamens. In the 

 form of its calyx and corolla it agrees, as we have already stated, with Spa- 

 thodea, and in the parallel cells of its anthers and exserted stamens, with Mil- 

 lingtonia. From the shortness of the ovarium, we suspect that a considerable 

 difference will be presented by the mature fruit from the rest of its coordi- 

 nates. The habit, as already noticed, is altogether that of f^erbenacece.
