Tree with striking four-lobed, blunt-ended leaves.
No interactions present.
Hilliers Manual of Trees & Shrubs makes no mention of leaf size, but does mention the narrow waisting, and states that they are more glaucous beneath than L. tulipifera; with smaller,greener less yellow flowers.
The Collins guide (2007) has pictures of the leaves of both trees, and says the leaves are up to 20cm long. Unfortunately, I didn't note any observations regarding the undersides of the leaves.
the young leaves are copper coloured which is supposed to be a characteristic of chinense. the leaves also seem to be blunter than tulipifera
Cassells 'Trees of Britain and Northern Europe' has excellent illustrations of both species,and states that it is very hard to distinguish between the two.Also that it is rare in cultivation, and that any leaf differences are not a constant feature.I have rarely seen L. chinense outside of botanical collections,so I would say it is much more likely to be L. tulipifera, which can also have large leaves is much more commonly planted.

It would be better, if we had a flower. but I vote for L. chinense because
1. deep incision of the leaves
2. smooth bark
3. blueish backside of leaves
... although it is true, that Liriodendron chinense outside a botanical Garden is more than rare.

The tree was observed on farmland beside a brook, close to the farmhouse. The tree was not in a garden, but looks ornamental.
