The most remarkable characters of this plant, and which separate it from 
all other known genera of Bignoniaceæ, 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 Verbenacew. 
From the position which the Bignoniaceæ occupy in the series of natural
