Qucrcus palustris. 
POPULUS firanclidenlafa penduliformis (Syn., P.Gneca ! 
penduta). II'replug Poplar. A decidedly pendu¬ 
lous form, with long, slender branches, and bright 
green, dentate leaves. J he growth is strong, the 
tree hardy and reliable. 
P. nigra Italica (Syn., P. dilalala). Lombardy 
Poplar, livery one is acquainted with this old relic 
, of a generation of past gardeners. If is the most 
■ fastigiate of erect-growing trees, and for producing 
, marked effects in grouping it has no equal. 
;P* “Volga” (?). Russian Poplar. A new and very 
much eulogized tree, of whose antecedents we have 
but little information. It is claimed to be extremely 
hardy and a rapid-growing shade tree. 
PRUNUS. Plum, Cherry, etc. 
Although grown largely for their useful crops of 
Iru", this Valuable genus supplies our collections with 
species of the most ornamental character. The newer 
introductions from Japan are exceptionally showy and 
have proved entirely hardy with us. 
P. avium II. pi. Common Double-Flowering Cherry 
A beautiful .form of the ordinary black-fruited 
( berry, with perfectly double, pure whit; blossoms, 
! produced ill clusters and in great profusion. Grows 
large, and is very conspicuous when in bloom. 
1. Mnhaleb. Mahaleb Cherry, Perfumed Cherry. A 
small tree, native of Europe, with rounded head 
pale, smooth bark, and ovate, smooth leaves. The 
corymbs of flowers are pure white, exceedingly 
fragrant, ami so numerous as to cover the entire 
surface of the nranches. 
P. Patitts European Bird Cherry. A small tree, with 
spreading branches, native of Europe and northern 
Asm. It is one of our finest ornamental trees, es- 
PRUNUS. continued 
pecially when covered with long, drooping clusters 
of white, highly fragrant flowers. Generally 
branched from the ground, resembling a round, 
dense mass of foliage. 
P. pendula. Japanese IVecping Cherry. A truly 
beautiful small or medium-sized tree, with lono- 
very slender branches and a multitude of pretty pink 
flowers. It is quite hardy and forms a conspicuous 
object in a collection, resembling a living green 
fountain. 
P. pseudo-cerasus. Japanese Double-Flowering 
Cherry. These magnificent trees, of which we cul¬ 
tivate two distinct colors, can not be adequately 
described, except by comparing them to charming 
double roses. One form has white flowers and the 
other bright pink bloom. Both are hardy and re¬ 
liable. 
P. serotina. IVild Black Cherry. A well-known na¬ 
tive species, forming quite a large tree, with elon¬ 
gated racemes of conspicuous white, delightfully 
fragrant flowers, preceding globular, dark purple 
fruit. 
QUERCUS. Oak 
The most valuable genus of trees in the entire list, 
not only for their estimable lumber, but for their value 
as forest trees, for parks and lawns of every descrip¬ 
tion. In congenial soils and with proper cultivation, 
they are not of slow growth, and their spreading 
heads and healthy foliage entitle them to prominence. 
Q. alba. White Oak. One of the largest and most 
desirable of our native deciduous trees. Although 
common in our forests, it is certainly unsurpassed 
for lawns where it can develop its proportions. 
Leaves smooth, bright green above, glaucous 
beneath. 
Q. coccinea. Scarlet Oak. A large tree, native of the 
United States, with deeply lobed leaves of shining 
green, changing in autumn to brilliant scarlet, it 
is one of our most beautiful shade trees, and worthy 
of extensive distribution. 
Q. macrocarpa. Bur Oak. A native western tree, 
striking in character and of medium size. The 
branches are usually covered with corky bark, and 
the large leaves are distinctly marked, being very 
deeply lobed, pale beneath. 
Q. palustris. Pin Oak. Perhaps the most popular spe¬ 
cies for ornamental planting. Generally of medium 
size, with drooping branches and bright green, 
shining leaves. For either lawn or avenue planting 
it is an exceedingly handsome tree. 
Q. phellos. Willow Oak. As its name suggests, this 
beautiful native tree resembles the willow family in 
the shape of its leaves, which are narrow and with¬ 
out any lobes. It grows rapidly and forms a large 
or medium-sized tree. Grows in low grounds. 
Q. prinus. Swamp Chestnut Oak. A fine large native 
tree, found mostly in moist soil but well adapted to 
t,r y* light ground. Leaves resemble the chestnut in 
character. Growth moderately rapid, of pleasing 
appearance. 
Q. robur. British Oak. A large umbrageous species 
that has proved generally reliable with us. The 
foliage is not unlike our White Oak’s but smaller. 
Iree a rapid grower when fully established, and 
valuable for lawn planting. 
var. atropurpurea. Purple-Leaved Oak. An at¬ 
tractive form, with rich dark purple foliage, retain- 
ing its color well through the summer. It presents 
a rounded, compact head, with an occasional 
clipping of the stronger shoots.
