A friend sent me these pictures and asked if could identify it. I am drawing a complete blank. Anyone care to have a go?

What about Laburnum (anagyroides)?

Flowers will clear it up John. You'll have to be patient!

That was my first thought until I saw the bark and the size and shape of the trunk. What I recall of Laburnum trunks is smooth, olive green with lenticels. These big shaggy slabs of bark have thrown me. Also seems terribly old for a Laburnum, usually they peter out after 40 or 50 years. Perhaps I have just not seen enough Laburnums......think I see a few lenticels.........

I have Laburnum anagyroides in my garden and yes, the bark is smooth and green.
-
Friend & I are leaning to L. alpinum as there's one leaf where you can see the glabrous underside.......maybe. Must be an oldster.

It was the bark on the trunk that threw me away from Laburnum - even though the foliage is very similar - if more leathery looking. :-\ :-\

You're quite right Maggi, the foliage texture is more reminiscent of oak rather than Laburnum.

My oldest Laburnum is around 30 + years and is a triple trunk so the diameter of the trunks is about 20- 25 cms
Here are some pix of the trunks of it
Laburnum x watereri ( - and it's a rather good flowering form!)

That's the other thing Maggi, older Laburnum trees here are usually multi-trunked too. I doi imagine I can see vestiges of lenticels on the smoother section of the bark in this cropped photo or maybe I should clean my specs.

How is the bark higher up in the crown?
I vaguely remember seeing a very old Laburnum in Oslo with somewhat similar bark to yours many years ago.

Trond - My problem is the owners asked the gardener what kind of tree it was, the gardener asked a friend and the friend asked me. So with the long weekend it's impossible to find out anything as the everyone's away and I only have a vague idea where the property is. I'd say it is either L. alpina or x watereri.
The leaf texture is puzzling, so stiff.
I've gone through the entire genera of legumes and it can only be Laburnum.

A random thought ... what about Laburnocytisus adamii ?

Hey Maggi that's a good fit!

I'd keel over if it were. Hardiness is questionable here and the size would make it one of the biggest on this continent I'd think.
