What is this and how do you tell?

Uk tree, what is this and what are the tells please?

[doc henderson]

any bark or leaf pics?  we (and I use the term loosely) would need a fresh cut end grain pic enlarged or magnified.  I am not the one you seek however to analyze that pic.  there are others on the forum that can help with that.

The main thing is a better pic, from that one I'm rather sure it is round.. It is an oak from the ring porous growth and obvious rays. You have a possible metal streak in the lower right. Quercus Robur is the most common woodland tree there I believe.

the rays I thought were saw marks.?

[Ron Wenrich]

You need to blow the picture up.  There are saw marks, but there are also rays.  Looks like some sort of white oak.  Quercus robur fits.

How do you tell?  The rays put it in the oak category.  The brown heart is typical for white oak. The pores in the wood look to be plugged (occluded).

Agree, see rays but a clean cut (sharp chisel or knife) and clear photo showing the cell structure, along with a photo of the bark. Will help.

Yes, like the guys mentioned there are rays, radially. And saw marks laterally. The end needs to be clear, cut smooth with a knife and magnified a bit.

Most of us here are mostly familiar with NA tree species, of which there are 2 or 3 wood technology and wood ID books written about them used in forestry colleges. They have clear magnified end grain photos and descriptions written up and ID keys to narrow down the possibilities. Along with a tree anatomy section as well as wood properties by species. A sharp knife and a 10x hand lens are essential to see the wood grain well when you are unsure, along with a handy reference or lots of experience. You first have to know what a wood ray looks like, what ring porous is, what tylosis is, what a growth ring is. What is sapwood? heartwood? Late wood? Early wood? Vessels? What?? ;)
