Variety. 
¥% F. a. 2 latifolia has broader 
leaves than the species. 
Hort. Soc. Garden, in 1835. 
Early in spring, the leaflets are 
covered with.a light down, which gra- 
dually disappears, till, at the approach 
of summer, they are perfectly smooth, 
of a light green colour above, and 
whitish beneath. This difference in 
the colour of the surfaces of the 
leaflets is peculiar to this species ; ™ 
and hence it has been named F. dis- 
color. It is also called the white ash 
from the colour of its bark, by which 
it is easily distinguished, in America, 
from the other sorts indigenous there. 43 
In Britain, all sorts of American ash & 
are readily known from Fraxinus 2 
excélsior, by their lighter bark, and by 
the paler green of their leaves. 1255+. americana,
