Sorbus bristoliensis, I reckons

 

 

 

Warmish

 

The info behind the leaf is not a clue

Second ones torminalis.

Quercus acuta?

 

 

Here you go boys and girls, try this one......

[Giles Hill]

Total guess - willow oak?

Well done that man! It is indeed Quercus phellos.

Sorbus bristoliensis, I reckons

 

In Hampstead, North London?

 

I think there's only about 300 of the bristoliensis.

 

I'm plumbing for Sorbus latifolia - The Service Tree of Fontainebleau

 

Hybrid of S. aria & S. torminalis

 

The only thing that's puzzling me is the height

 

As is evident in the first shot, it is searching for light through very dense canopy.

I don't think it is Sorbus latifolia. Your book and my one describe the leaves as being as broad as they are long, I've just google imaged this, which I think shows what is more typical for the leaf shape:

 

European Mountain-ash - Sorbus latifolia

 

I read somewhere that sorbus is one for having lots and lots of local forms so it might be something odder.

Interesting point Giles, you may be right.

 

there were many variations in leaf broadness over the canopy, much like the last shot on your link.

 

Will chase this some more me thinks.

 

Ftr, I tend not to trust books entirely

Interesting points there- i know what you mean about books- in two different books the colour and shape of s.latifolia leaves appears different, and looking at the pic in the book in your post he image is slightly different again. I would say that the broadness of the lower part of the s.latifolia seems a little more pronounced than on the leaf you have photo'ed, which seems to turn in more at the bottom- more oval as opposed to wider toward the base. Also, are the indents forming the lobes pronounced enough to be s.latifolia. Books!:confused1:Maybe it is a local variant?

Me neither.

 

The image below wasn't my idea of S intermedia, but I thought it looked like your photo and was quite confident when I made the suggestion.
