Can anyone ID this tree? It is a many-branched tree about 25-30ft tall, spreading branches, light airy foliage effect. Note the little 'fruits' developing in the leaf axils. These have 3 stigma branches and are these size of one of those silver balls that you sometimes get on cakes! The bark has prominent horizontal lenticels.

The teeth along the edge of the leaf are not the same as Wych Elm.

If I knew then I would not be asking! The bark is not like the one I described which has prominent horizontal lenticels similar to cherry. It's in an arboretum so is probably something special!
