Only got photos of the leaves and seeds/nuts.

The leaves are a lighter green than in the photo.

Identification would be very helpful. Thanks guys.

Don’t know where the photos are. They are linked properly???????

All my tree books are next door, if I remember in the morning I’ll have a look for you!

platanus x hispanica

possibly a variety of Platanus

Got pic of the whole thing, planes have peeling bark which is pretty unmistakeable?

Variable shaped leaves look a bit like white mulberry, but the fruits are a bit of a mystery.

The other possibility that occurs to me, before I put on my tartan shirt pick up my axe and head off into the wild woods of N London, is Osage orange, Maclura pomifera, which is pretty rare and won’t normally fruit unless you have male and female trees in the vicinity. It has large thorns on the twigs.

Was there a baby robin in it?

Not one that springs to mind, but my Dad is a local Tree Warden & will let him have a nose over the pictures to see if he knows?

No thorns. It’s a single tree in a small rear garden in Richmond (London).

The photos of the actual tree came out pony and worthless.

IIRC the bark is grey/green and smooth.

I’ll get some more photos from site.

ETA: Thanks to all so far.
