Orangish brown colored stems and distinctly grooved. After the foliage falls they are rough due to the pulvinus remaining. See image of leaves above to see the grooved twigs. Bark deeply fissured, brown and dark brown.
Misidentification: not sure, if you will have a problem with this one, look at the leaves, the angle they are held from the stem (P. abies is green and held about 45 degrees to the stem).
Quite a few around, none look that great, they really need a colder winter and warmer summer. Best over the hill or even better in Oregon.
