Populus fremontii S. Watson var. thornberi Sargent
Populus fremontii subsp. fremontii is seen most commonly alongside larger rivers and creeks and in canyons in the Gila National Forest. The limbs tend to be weak and break off easily, such that there broken limbs scattered around the bases of larger trees. The trees with "their feet in water" can grow to enormous size. Sometimes a fallen horizontral trunk will sprout new branches. The bark is gray and deeply furrowed. The leaves are coarsely serrate and broad. The trees are dioecious-- male and female catkins form on different plants. The female (pistillate) flowers are green and turn into the characteristic cottony seeds. The male (staminate) flowers have a more yellow appearance.
