The Sexes. Plants of the male are plentiful in England. The female is known to be extant in Lom- 
bardy, whence we have received dried specimens and seeds in November, 1836. (See Gard. Mag., 
vol. xii.) M.C. A. Fischer, inspector of the University Botanic Garden, Géttingen, found, in 
1827, a single plant of the female, after having many years before sought fruitlessly for it, among 
many thousands of plants around Gittingen. (See Gard. Mag., vol. vi. p. 419, 420.)

Spec. Char., §c. A very distinct kind, having the form of the cypress tree, 
from its branches being gathered together about the stem. (Willd.) Petiole 
compressed. Disk of leaf deltoid, wider than long, crenulated in the whole 
of the edge, even the base; glabrous upon both surfaces. (Ait. Hort. Kew., 
and Spreng.) Leaves in the bud involutely folded. A tree, growing to 
the height of from 100 ft. to 120 ft.,and sometimes to 150 ft. Introduced 
from Italy into Britain about 1758, and flowering in March and April.

Description, §c. 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. fastigiata and 
P. nigra is, that the former produces suckers, though not 
in any great abundance; while the latter rarely produces 
any. /. fastigiata, also, in the climate of London, pro- 
trudes its leaves eight or ten days sooner than P. nigra. 
The male catkins of P. fastigiata, wetted and laid upon 
paper, stain it of a deep green. 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 Oxford- 
shire, 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. The Lombardy poplar is but of 
short duration ; for, though a tree from one of the original 
cuttings brought home by Lord Rochford still exists in a vigorous state at 
Purser’s Cross, yet the trees at Blenheim, and other places, planted about 
the same time, or a few years afterwards, are in a state of decay. 
Geography, History, §c. The Lombardy poplar is considered, by Signor 
Manetti and others, as wild in Italy, particularly in Lombardy, on the banks 
of the Po; because it has been observed that, when that river overflows its
