A* radiata. 
Bignonia radiata, Z,m. 
This beautiful new genus I have dedicated to the memory of 
Archibald, Duke of Argyle, a nobleman distinguished for his pa- 
triotic virtues and love of science, and more especially of botany. 
His fine garden at Whitton Park, in Middlesex, was justly cele- 
brated towards the middle of the last century. It contained a very 
extensive collection of plants, particularly of ornamental and use- 
ful American trees, many of which he himself first introduced to 
this country. There are many fine specimens of Argylia in the 
Lambertian Herbarium, from Don Jose Pavon, collected in the 
Peruvian expedition. Linnaeus, and all other botanists, with- 
out having seen the plant, have very improperly referred it to 
Bignonia , and to give their opinion, perhaps, the more weight, 
they have marked it as shrubby. The figure given by Father 
Fewillie is much too diminutive, and is calculated to convey but 
a very imperfect idea of this elegant plant.
