Lewis. Missouri Silver-tree. In the collection of 
A. B. Lambert, Esq., are specimens from Dr. Pallas, 
under the name of E. latifolius , which approach very 
near to the present, species ; but the leaves are longer, 
and but slightly covered with that silvery substance 
on the upper surface, which in the present one is equal 
on both sides: besides, the flowers are generally aggre- 
gate : it is probable that both belong to the same spe- 
cies, different from E. latifolius of Linnasus, which 
I do not know.

On the banks of the Missouri. M. Lewis. I? . v.s. in 
Herb. Lewis, c. fr. This shrub resembles Elceagrus 
argentea so much, that they might easily be mistaken 
one for the other when without fruit ; but this species 
bears really a berry, different from the drupa of the 
other genus. The flowers are according to information 
from Mr. Nuttali four- cleft, and resemble those of 
Elceagrus very much.
