The branches are curly.
In the lower part of this picture, you can see two twigs that go straight up.
The bark is kind of orange/tan with angled lines on the trunk and lower, larger branches.
The smaller branches have smooth, greenish bark.
The leaves reminds me of blades of grass. I think leaves of this shape are called lance-shaped or lanceolate. To me, the leaves look compound, because they grow from what looks like a green stem, rather than a woody twig. However, apparently corkscrew willows have simple leaves.
The flowers are catkins.
