I want to know the answer to the following question:
What species do aspen, cottonwood, and poplar trees belong to?
All the background I'm provided with is that "Examples of this kind of wood are alder, basswood,[citation needed] birch, buckeye, maple, willow,and the Populus species such as aspen, cottonwood and poplar.". Is that enough to answer the question?
Answer: yes
