Th e Lombardy poplar is readily distinguished from all o th e r trees o f this
genus by its tall narrow form, and by th e to ta l absence of horizontal
branches. The tru n k is twisted, and deeply furrowed ; and th e wood, which
is small in quantity in proportion to th e height o f th e tree, is of little worth
or duration, being seldom of such dimensions as to admit o f its being sawn up
into boards o f a useful width. The leaves a re very similar to those of
P . nigra, and th e female catkins to those o f P . monilífera ; th e male catkins
resemble those o f P . nigra, and have red anthers, b u t are considei'ably more
slender. One difference between P . fastigiàta and P . nigra is, th a t th e former
produces suckers, though n o t in any great abundance, while th e latter
rarely produces any. P . fastigiàta, also, in th e climate of London, protrudes
its leaves eight or ten da;ys sooner than P . nigra. T h e ra te o f growth of
P . fastigiàta, when planted in a loaniy soil, near water, is very rapid. In the
village o f Great Tew, in Oxfordshire, a tree, planted by a man who, in 1835,
was still living in a cottage near it, was 125 ft. high, having been planted about
50 years.

Th e shoots o f this species, when young, a re extremely su c cu len t; and, as
they continue growing late in th e summer, they are frequently killed clown
several inches by th e autumnal frosts. After th e tre e has attained th e height
o f 20 or 30 feet, which, in th e climate of London, it does in five o r six years,
this is no longer th e c a se ; because th e shoots produced are shorter and less
succulent, and, o f course, b e tte r ripened. According to Michaux, the leaves

long on young plants,
ancl as much in
breadth ; while on
trees 30 o r 40 feet
high they are only
one fourth th e size.
As an ornamental
tree, it forms a very
stately o b je c t; but, from the brittleness o f th e branches, they are very liable
to be torn off by high winds. Th e wood is o f little use either in Ainerica or
England. Propagated by layers, as it strikes less freely from cuttings than
most o f the oth e r species.

roundish ovate, having a small sinus a t th e base, and being slightly auricled

and on the western rivers. Height 70 ft. to 80 ft. in America ; 8 ft. to 10 ft.

greenish yellow ; April ancl May.
We have never seen plants o f this species higher than 5 or 6 feet ; though
a sjiecimen tre e in th e Mile E n d Nursery, and ano th er a t Syon, must have
been planted more than 50 or 60 years ; ancl though it is said by Bosc to be a
lofty tree in th e neighbourhood o f Paris.
It is a very remarkable species, from the
particular character o f its leaves, which,
though as large as, o r larger than, those
of P. angulàta, and something resembling
them in outline and in position on th e
branches, yet have nearly cylindrical fo o tstalks,
and the ir disks hanging down on
each side from th e midrib in a flaccid
manner, not observable in any other spe
cies of the genus. Th e young branches
and the annual shoots are round, instead
of being angular, like those o f P . angulàta,
P. canadensis, and P . monilífera. The
leaves, while very young, are covered
with a thick white down, which gradually
disappears with age, till they a t last 1506. p. neterophyiia.
become perfectly smooth above, and
slightly downy beneath. P ropagated by marching on any o f th e varieties of
P. nigra. I f this species were grafted a t th e height o f 30 o r 40 feet on P.
raoniiiferaj it would form a very singular and beautiful drooping tree.
