DECIDUOUS ORNAMENTAL TREES.

part of this state, a fine tree, with smooth, unequally-toothed 
wide cordate leaves ; and the Carolina poplar, (P. angulata ,) 
an enormous tree, of the swamps of the south and west, 
considerably resembling the Cotton tree, but without the 
resinous buds of that species. 
Among the European kinds, the most ornamental, as we 
have already remarked, is the Silver aspen, White poplar, or 
Abele tree, (P. alba,) which grows to a great size on a deep 
loamy soil, in a very short time. The leaves are divided into 
lobes, and toothed on the margin, smooth and very deep 
green above, and densely covered with a soft, close, white 
down beneath. There are some varieties of this species 
known abroad, with leaves more or less downy, etc. Sir J. E. 
Smith remarks in his English Flora, that the wood though 
but little used, is much firmer than that of any other British 
poplar ; making as handsome floors as the best Norway fir, 
with the additional advantage that they will not readily take 
fire, like any resinous wood. 
The English aspen, (P. tremula ,) considerably resembles 
our native aspen ; but the buds are somewhat gummy. The 
Athenian poplar, (P. Grceca ,) is a tree about 40 feet high, 
with smaller, more rounded, and equally serrated foliage. 
The common Black European poplar, (P. nigra,) is also 
a large, rapidly growing tree, with pale-green leaves slightly 
notched : the buds expand later than most other poplars, and 
the young leaves are at first somewhat reddish in colour. 
The Necklace-bearing poplar, (P. monilifera,) so called from 
the circumstance of the catkins being arranged somewhat 
like beads in a necklace, is supposed to have been derived 
from Canada, but there are some doubts respecting its origin : 
in the south it is generally called the Virginia poplar. 
The Lombardy poplar, (P. dilatata ,) a native of the banks
