CHAP, CIII. SALICA CEX. PO PULUS. 1657 
40 ft., with a trunk 12in. or 15 in. in diameter; found 
by Michaux on the banks of the river Hudson, a little 
above Albany; and by Pursh about Lake Ontario. 
Judging from the plants in the collection of Messrs. 
Loddiges, and Michaux’s figure, we have no doubt 
whatever of its being, like P. canadénsis, merely a variety 
of P. nigra. It is, however, tolerably distinct ; and, being 
a small, neat, deep-green-leaved tree, well deserves a 
place in collections. 
Statistics. In England, in Devonshire, at Endsleigh Cottage, 16 years 
planted, it is 50 ft. high, the diameter of the trunk 14in., and of the head 
12 ft. ; in Buckinghamshire, at Temple House, 40 years planted, it is 60 ft. 
high, the diameter of thetrunk 2 ft., and of the head 30 ft. Price of plants 
the same as in P. canadénsis.

Derivation. The epithet necklace-bearing alludes to the shape of the female catkins, which in their 
capsules, and the manner in which these are attached to the rachis, resemble strings of beads. 
Swiss poplar, and black Italian poplar, allude to the tree being very abundant in Switzerland and 
the north of Italy. 
The Sexes. Both sexes are frequent in British collections, but the male is most abundant. Both are 
in the London Horticultural Society’s Garden. The female is figured and described by Watson 
(see Dend. Brit., t. 102.), who has figured some parts of the male flower in the same plate. Bosc 
remarks that only the male is cultivated in French gardens.

Spec. Char., §c. Shoot more or less angular. Branch round. Petiole 
slender, compressed in the upper part; in some leaves, shorter than the 
disk, in others longer. Disk deltoid, glanded at the base, which is sub- 
cordate in some leaves, and very obtusely wedge-shaped in others; tip 
acute; edge serrated all round, except in the central part of the base, and 
at the acute tip, the teeth have incurved points; glabrous, except in the 
edge, which, at least when the leaf is growing, is ciliate; edge ultimately, 
and perhaps early, gristly. Male flowers about 30.in a catkin, upon pe- 
dicels. ractea glabrous. Stamens 16, a little longer than the corolla. 
Female flowers about 40 in a catkin. Stigmas 4, dilated, jagged. (Pursh, 
Wats., Michx., Spreng., and obs.) It is rather doubtful to what country 
this poplar is indigenous: Canada is given as its native country in the 
Hortus Kewensis ; but, in the Nouveau Du Hamel, it is stated to be a native 
of Virginia. Michaux, jun., states that neither he nor his father ever found 
it wild in America; and Pursh adds that he has only seen it in that 
country in gardens. According to the Hortus Kewensis, it was introduced 
into Britain by Dr. John Hope, in 1772. It is a tree, according to Pursh, 
- from 60 ft. to 70 ft. high in America; but in Britain it grows to the height 
of 100 ft. or 120 ft., or upwards ; flowering in March, and ripening its seeds 
about the middle of May. 
Varieties. 
¥.P. m, 2 Lindleyina Booth; the new waved-leaved Poplar, Hort. ; has 
rather larger leaves than the species, and they are somewhat more 
undulated. The plant in the London Horticultural Society’s Gar- 
den is 13 ft. high. 
¥ P. m. 3 foliis variegatis Hort.— The tree in the Horticultural Society’s 
Garden is between 30 ft. and 40 ft. high; but its variegation is by 
no means conspicuous, except in early spring. 
Description, §c. P. monilifera is the most rapid-growing of all the poplars ; 
and its timber is equal, if not superior, in quality to that of any other species.
