This tree is in our garden in Bath- my discription is:
Tree- unknown. Deciduous. Flowering mid June.
Age- probably greater than 50 years. Much pruned over a long time. Height about 6m
Bark is fissured mid brown.
Leaf stalk angle about 90deg. Twig angle about 60deg.
Leaf Type- simple. Margin is entire. Light coloured main vein, lateral veins very fine. Olive green matt top surface. Underside is pale whitish green, matt. Again almost but not visibly hairy. Leaves are single and alternate.
Leaf length 9-12cm, width 1 to 1.5cm. Angle away from a flat leaf about the main vein 30-60deg making an open vee, i.e. looking down on the top the two halves come up from horizontal.
What maybe lenticels are round and green/brown compared to the newer light green twigs
The very pale green just un-opened/ opened flower is 1-1.2cm long, 5mm square section then tapered to a point. Flowers are 4 yellow, pointed triangular 5 to 6mm long from the common part, where the 4 petals are joined together on their edges, bending back as far as parallel to the flower stem. The depth of the common part is about 5mm, 3mm square.
The white stigma projects about 1mm above the common part, the 4 anthers only reaching the point where the petals separate and bend outwards. The anther yellow is just slightly darker than the colour of the petals.
The problem is apparent sudden loss of nutrient to branches, at the moment causing yellowing of leaves. Last year branches lost leaves early.
It would be just nice to know what it is. If the problem is just old age then we can see about replacing it.

Thank you- looks very likely. In our context it has an attractive foliage and has not spread. I can't recall it having popular fruit. Do you think old age is reasonable or is it a treatable problem? Pruning off parts doesn't seem to answer it.
I concur with Steve on the ID (I suspect E. angustifolia) (though Daphne has some similarities).
If I may but-in:
- can you describe its situation: soil, crowding, shading, other plants with similar problems nearby...
- tell us more about the yellowing: are you familiar with how the (evergreen) tree normally goes through a period of old leaves yellowing before they fall, and is this different to that?
