in the form of their flowers and fruit, we have had no opportunity of judging ; 
having only heard of one American ash which has ripened seed in England, and 
never having seen the flowers of any of the sorts. Supposing all the alleged 
species of American ash to be but varieties, they will not be more numerous 
than the varieties which are, or might be, distinguished, of the common 
European ash ; and not half so many as there are of Quércus Cérris, Q. Ilex, 
and other species of oak, of which nobody takes any notice, because they 
cannot be readily propagated by grafting. 
Sorts of American Ash, of which Seeds may be procured from the London Seeds- 
men, more particularly Mr, Charlwood.

Spec. Char., §c. Leaflets 7, petiolate, oblong, acuminate, shining above, quite 
entire, glaucous beneath. Flowers calyculate. (Don’s Mill., adapted.) A 
tree, a native of North America, from Canada to Carolina, in woods. In- 
troduced in 1723, and flowering in May. 
Variety. 
¥ F. a. 2 latifolia has broader leaves than the species. The plant of this 
variety in the Horticultural Society’s Garden was, in 1835, after 
being 10 years planted, 11 ft. high. 
Description, Geography, Sc. In 
Michaux’s North American Sylva, F. 
americana is said to be one of the 
most interesting among the American 
kinds of ash for the qualities of its 
wood; and the most remarkable for 
the rapidity of its growth, and for the 
beauty of its foliage. It rises with a 
straight clean trunk, often undivided 
to the height of more than 40 ft. The 
leaves are 12in. or 14in. long; the 
leaflets 3in. or 4in. long; and they 
are borne on short petiolules. Early 
in spring, the leaflets are covered with 
a light down, which gradually disap- 
pears, till, at the approach of summer, <= 
they are perfectly smooth, of a light 
green colour above, and whitish be- 
neath. This difference in the colour 
of the surfaces of the leaflets is pecu- 
liar to this species; and hence it has 
been named F’. discolor. It is called ZZ 
the white ash from the colour of its 
bark, by which it is easily distinguished, 
in America, from the other sorts indi- 
genous there. In Britain, all sorts of American ash are readily known 
from Fraxinus excélsior, by their lighter bark, and by the paler green of
