Close-ups of the leaves of what appears to be Scouler's willow as seen along the Springwater Trail between Gresham, OR and Boring, OR...........July 8, 2011. Note the rusty colored hairs on the veins on the otherwise glaucous undrside of the mature leaves which evidently helps identify this species from the similar (in appearance?) Hooker's willow (Salix hookeriana) and Sitka willow (Salix sitchensis).

A close-up of the staminate catkin of Scouler's willow which begins blooming before the leaves emerge, as seen in the photo at right. This tree-like or large shrubby willow is one of the first willows to bloom in the spring. Photographed along the Springwater Trail adjacent to Powell Butte several miles west of Gresham, Oregon..........March 19, 2012. Note that this species has 2 stamens per flower while the similar pacific willow (Salix lasiandra) has 3-6 stamens per flower.
