Help with tree ID required please

[The Woodman]

I would be very grateful for a steer on this tree species growing in a small collection of rarities.

About 7-8m tall and mature.



Big leaves, 6 inches long and big leaf scars on the twigs.



Buds are very, very small.





Stripped green twig bark smells like that of Prunus padus

This one's got me beat!

Any help gratefully received.

Is it a Black Jack Oak of the red oak family .Nativeof Southern USA.

[Hedera]

Quercus velutina - Black oak, like Black Jack Oak from USA, has larger more varied leaves. Sometimes split mid=rib.

trying Red Maple now...

Deffo an American - but can't decide which.
Other times of the year will give us all more clues.

It has a bad break-out wound, - let's hope someone can get some acorns germinating off it soon.

There are over 50 species of Oak recorded as native to America, and over 600 species world-wide.
I am surprised if this tree is in among a collection of rare species that it wasn't labled.
It has a Red-Oak or White Oak look about it to me; the leaves of which can be very variable. But I'm really only guessing, as I am by no means familiar with more than a very few of the many possibilities.

Sargent's "Trees of North America" is available on Biodiversity Heritage Library. Although old this is still a very useful work. The first 10 or so entries ought to include what you are looking for. Off the top of my head I'd suggest looking at Pin Oak, but this is not a hugely informed opnion.

Information about Chinese oaks can be found in the Flora of China site of the Missouri Botanical Gardens.

At least the Oak family seems to crop up.Must be a list on the plantaion somewhere I should think.

Thanks to you all for those suggestions. Perhaps the trees were labelled in former times, there are no signs of them now unfortunately.

I didn't see any acorns when rooting about in the leaf litter. The size, form and smell didn't suggest an oak to me but I agree with the black/black jack/red/white etc route. I've looked at all the suggested species leaves on Google Images and think that the black/black jack have the best resemblance but know that's not the end of it!.

I'm going to go back when the tree is in leaf and have another look

The timber showing in the old wound is rock hard and there's no rot at all.

I found an informative short video and other links here....

Thanks again, another door opened into a room full of species I've never encountered!
