Petrified wood polished plate. Please help with ID

[Ludwigia]

I recently purchased this along with a number of other fossils. The only drawback was that there was absolutely no information to be had on them, but I jumped at it since it was such a good deal. Now I'm hoping that somebody out there may have an idea what type of wood this is and where it might come from.

Sorry Roger, I’ve got nothing for you on ID.  

 

I did want to say that it is a very nice piece, and if you got a deal it had to be nearly impossible to pass up! 
 

I love the visible growth rings. The various “cracks” (for lack of a better word) and inward curve of growth rings is very interesting! Such as what I circled below. You see this sort of thing in cross sections of modern wood. Evidence that your particular piece was alive and that it suffered some sort of damage at an early age. It obviously lived through it and continued to grow, but kept the scar of it’s trauma for life. It’s a very cool added bonus to me when a fossil can tell a story.

Maybe willow, maybe from Oregon.

Thanks for the suggestion.

@paleoflor @Plantguy ? I know that you guys are more specialized in recognizing soft parts, but I thought I'd ask anyway if you might recognize the pattern. After looking at a lot of wood cross sections in the Net, I have the feeling that this comes rather from a Cenozoic site than an older one. Oregon would certainly be a candidate in that case.

In terms of the colouration and appearance of the tuff matrix, the specimen looks very similar to material from the early Permian of Brasil.

Thanks for your input, but I think those are mostly ferns, aren't they?

It is rockwood silicas. Don't know where it is from though.

Sorry, but I don't get the joke

You asked what the type of wood is.

Agatized petrified wood = rockwood silica(s)

 

 

Sorry, My sense of humor is somewhat off these days.

Mostly, perhaps, but not certainly not exclusively. Conifers and calamiteans also occur frequently. Your specimen would belong to the former group.

I googled rockwood silica just for fun and ended up in a mine in Minnesota.
