Other common names: _White elm_.

Comparisons: The _English elm_ (_Ulmus campestris_) is also a tall,
dignified tree commonly seen under cultivation in America, but may
be told from the American species by the difference in their general
contour. The branches of the English species spread out but do not
arch like those of the American elm, and the bark of the English elm
is darker and coarser, Fig. 38. Little tufts of dead twigs along the
main branches and trunk of the tree are characteristic of the
English elm and will frequently help to distinguish it from the
American elm.

The _Camperdown elm_ may be recognized readily by its dwarf size and
its low drooping umbrella-shaped crown.


LOMBARDY OR ITALIAN POPLAR (_Populus nigra, var. italica_)

Distinguishing characters: Its *tall, slender, spire-like form* and
rigidly *erect branches*, which commence low on the trunk, make this
tree very distinct at all seasons of the year. See Fig. 39.

Leaf: Triangular in shape, similar to that of the Carolina poplar but
smaller, see Fig. 40.

Range: Asia, Europe, and North America.

Soil and location: The poplar is easily grown in poor soil, in any
location, and is very hardy.
