of the Po, where it is sometimes called the Cypress poplar, 
from its resemblance to that tree, is too well known among 
us to need any description. Only one sex, the female, has 
hitherto been introduced into this country ; and it has con- 
sequently produced no seeds here, but has been entirely pro- 
pagated by suckers from the root. 
The Horse-chesunut Tree. JEsculus. 
Nat. Ord. iEsculacese. Lin. Syst. Heptandria, Monogynia. 
A large, showy, much admired, ornamental tree, bearing 
large leaves composed of seven leaflets, and, in the month 
of May, beautiful clusters of white flowers, delicately mottled 
with red and yellow. It is a native of Middle Asia, but 
flourishes well in the temperate climates of both hemispheres. 
It was introduced into England, probably from Turkey, 
about the year 1575 : in that country the nuts are often 
ground into a coarse flour, which is mixed with other food 
and given to horses that are broken- winded ; and from this 
use the English name of the tree was derived. 
A starch has been extracted in considerable quantity from 
the nuts. The wood is considered valueless in the United 
States. 
The Horse-chestnut is by no means a picturesque tree, be-

and close in its surface, to produce, an agreeable eflect in 
light and shade. But it is nevertheless one of the most beau- 
tiful exotic trees which will bear the open air in this climate. 
The leaves, each made of clusters of six or seven leaflets,
