I'e got this delicate little tree in the garden. At 25 years approx
it has stretched up to about 6m tall, and is about 150mm diameter at
the bole. It has tri-lobed divided leaves with pointed tips, and a
smooth, non-waxy surface.

My first thought was a form of Acer negundo, second thought was 'but
they have pinnate leaves' - then I looked at this.

It is a bit early for acers to be in flower though.

Acer platanoides (Norway Maple) is in flower at the moment. According to
Mitchell Acer negundo flowers in early March, in hanging bunches, which
would explain why the plant appears to be bearing immature keys. The
leaves of Acer negundo are ternate or 5- to 7-pinnate. I wouldn't expect
consistently ternate leaves on an individual tree, but that could be
ignorance on my part.

Googling for Acer negundo trifoliate finds a couple of other ternate-
leaved species - Acer buergeranum and Acer henryi.

I've checked my photographs of Staphylea, and S. colchica looks a fair
match for the leaves, but the flowers don't seem a match. A couple of
more species are S. trifolia (American Bladdernut) and Ptelea trifoliata
(Hoptree).
