Question
I have been puzzling over this aspen. The size of the leaves seems closer to P. tremuloides, but the size and number of the teeth seem closer to P. grandidentata. It is growing in a wooded area in the center of Connecticut. What do you think?
Answer
Dear hlbleaf, I can't be certain from the images you've provided, but you may have collected Populus X smithii (the hybrid of P. grandidentata and P. tremuloides). The hybrid typically shows more teeth per margin than yours is displaying, but the leaf blade shape and other features suggest this identification. Best wishes.
