Eastern cottonwood (Populus deltoides)

Leaves
     
Queen Elizabeth Dr between Landsdowne Park and Fifth Ave., May 10, 2008.
The one on the right is a very young plant. The petiole is flattened vertically like trembling aspen and the
leaves flutter in the same way.




Buds

I am not 100% sure this is Eastern Cottonwood, but I think so.

Similar species
Other trees in the same group as eastern cottonwood found in this area are balsam poplar, trembling aspen
and large-toothed aspen. All are characterized by vertically-flattened petioled which cause the leaves
to flutter in a breeze. They can be differentiated as follows:
Balsam poplar leaves are very dark green on the upper surface.
Trembling aspen bark is almost white, as if the tree was bandaged.
Cottonwood bark is very furrowed and leaves shape something like European birch, with an elongated tip.
