The distinction is really a semantic one.

Aspens (bigtooth - Populus grandidentata, and quaking - Populus
tremuloides) are of the poplar family.

In actual practice, most of the reading I have done suggests that the
hybrid poplar currently being promoted for biomass cultivation and
short-rotation forestry is a hybrid of some different cottonwood species
(also of the poplar family) and not aspen.

So, hybrid aspen is a form of hybrid poplar. Hybrid poplar is not
NECESSARILY hybrid aspen.
