Platanus: PLANE TREE or SYCA- 
MORE — Continued. 
ticularly valuable because of its handsome 
foliage. It is free from insect attacks 
and not as subject to disease as our native 
tree. 
Populus : POPLAR. 
As quick growing trees for damp 
places the Poplars are generally planted 
and some of them are very handsome. Al- 
though certain varieties are used for and 
serve a good ornamental purpose, they are 
as a group more generally planted as 
wind-breaks and to hold the banks of 
streams. Certain varieties are very good 
trees for Idaho, Montana, Eastern Oregon, 
Eastern Washington, and similar regions. 
P. alba. WHITE or SILVER POPLAR. 
Europe. This tree forms a round head; 
makes a rapid growth and is very good for 
quick results. The silvery velvet of the 
leaf linings is in sharp contrast to the dark, 
shining upper surfaces of the leaves. When 
the leaves are seen quivering in the breeze 
they give the tree a peculiar white appear- 
ance. 
P. var. Bolleana. BOLLES POPLAR. 
Very compact upright grower, resembling 
the Lombardy Poplar, with leaves glossy 
green above and white beneath. This and 
the Silver Poplar have two bad habits: their 
roots send up suckers, and their leaves ac- 
cumulate.and hold dust and coal soot until 
they become quite filthy. They should be 
planted to the back ground, where the 
suckers can be controlled without damage 
to the lawn and where distance lends en- 
chantment to the view of its foliage. 
P. Carolinensis. CAROLINA POPLAR. 
Native. Strictly a pyramidal tree of vig- 
orous and surprisingly rapid growth. For 
city use the varnish on the leaves protects 
them from dust and smoke. They should 
be planted, however, with the expectation 
of being replaced with the slower growing 
more desirable trees. The new growth 
should be well cut back for the first few 
seasons. 
P. nigra Italica. LOMBARDY POP- 
LAR. Europe. This tree is too well 
known to demand description. It makes 
a rapid upward growth, spire-like form. 
As a shade tree it is of little use, but is 
used with great success as an accent in 
planting where the brfBiching of other 
trees are horizontal. They add interest 
to the sky-line and are very fitting in their 
place. The twinkling of the green leaves 
gives an added interest. 
P. balsamifera. A large tree with a stout 
trunk, rapid luxuriant growth, large, shin-
