I was fortunate in meeting with numerous fine specimens of 
this splendid shrub, among many other new bignoniaceous 
plants, in an extensive Mexican collection lately received from 
Don Jose Pavon, and now deposited in the Lambertian Herba- 
rium. It forms a genus totally different from any hitherto pub- 
lished. It is distinguised from B’tgnonia by the confluent lobes 
of its anther, by its seeds being furnished with a villous pappus, 
and, lastly, by its habit. It differs from Tecoma, besides the 
characters above enumerated, in having a parallel, and not a 
transverse dissepiment, and from Spathodea (with some plants 
referred to which, it agrees in habit) it is readily distinguish- 
ed by the structure of its capsule, in having seeds furnished 
with a villous pappus, and, lastly, by the lobes of the anthers 
being confluent. The name, which I have given it, alludes to 
its brilliant flowers, and is derived from areas, venustus, and uv6os, 
fos.

The campanulate, trilobed calyx, the figure of the corolla, 
the parallel lobes of the anthers, and the structure and form of 
the capsule, are the marks which characterise this genus. The 
species referable to this genus are the two following, viz. 
1. I). dentatum, foliis elliptico-oblongis dentatis subtus pubes- 
centibus.
