828 ARBORETUM ET FRUTICETUM BRITANNICUM. 
Persia, and apparently indigenous in Italy. Height 100 ft. to 150ft. In- 
trod. 1758. Flowers red; March and April. Decaying leaves yellow. 
The Lombardy poplar is readily distinguished from all other trees of this 
genus by its tall narrow form, and by the total absence of horizontal 
branches. The trunk is twisted, and deeply furrowed ; and the wood, which 
is small in quantity in proportion to the height of the tree, is of little worth 
or duration, being seldom of such dimensions as to admit of its being sawn up 
into boards of a useful width. The leaves are very similar to those of 
P. nigra, and the female catkins to those of P. monilifera; the male catkins 
resemble those of P. nigra, and have red anthers, but are considerably more 
slender. One difference between P. fastigidta and P. nigra is, that the for- 
mer produces suckers, though not in any great abundance, while the latter 
rarely produces any. P. fastigiata, also, in the climate of London, protrudes 
its leaves eight or ten days sooner than P. nigra. The rate of growth of 
P. fastigiata, when planted in a loamy soil, near water, is very rapid. In the 
village of Great Tew, in Oxfordshire, a tree, planted by a man who, in 1833, 
was still living in a cottage near it, was 125 ft. high, having been planted about 
50 years. ;

The shoots of this species, when young, are extremely succulent; and, as 
they continue growing late in the summer, they are frequently killed down 
several inches by the autumnal frosts. After the tree has attained the height 
of 20 or 30 feet, which, in the climate of London, it does in five or six years, 
this is no longer the case; because the shoots produced are shorter and less 
succulent, and, of course, better ripened. According to Michaux, the leaves
