Yannick MourguesHi.
Who could identify the tree with this section ? Is-it possible ?
I think it could be Salix.
Do you agree ?

Re:Tree section
Yes Stip, this site is wonderful. Under "Species list" you find lots of European genera and species.

But for me Fraxinus is excluded, see under Fraxinus excelsior.

Salix is well possible, but a closer photo would be helpful

Re:Tree section
Hello,

isn't that what I believed to be called "ring-pored"?

best regards,

Yes, in my memory Fraxinus was more diffuse pored

Re:Tree section
Here you can compare. Salix may show a slightly more dense aggregation of the pores in the spring region but never has the big pores of Fraxinus and Quercus.

Re:Tree section
Hello Zotto,

yes, you are right, the pores are too diffusely scattered to be called truly ring-pored. I was misled be the seemingly big diameter of the pores, but may be that it due to that we don't know the scale of the foto.

best regards,
Andreas
