描述
The leaves are just emerging on this plant and the glaucous coating on the underside hasn't developed yet.
However, we can see that the catkins emerged well in advance of the leaves since they are sessile & done flowering . Green-leaved (not glaucous-backed) willows in AB with this general leaf shape would have the catkins on leafy branchlets.
S. pseudomonticola also has juvenile leaves reddish and leaf margins serrulate to crenate. Leafy stipules can also be seen developing here. Floral bracts are dark, leaf base rounded, leaf shape widely elliptic.
A female plant is right beside:
