When considering this flower from the perspective of not overlapping tepals it looks like T. megcalyptra but it is passed its best. But considering the leaf, this leaf is too narrow for for megcalyptra and more like that of T. alpina also present in this area. In most other features both species are similar. Would I be correct in assuming the leaf was about 15 mm wide rather than 25mm wide?

You would be yes.

All considered I think I will call this T. alpina particularly when considering the leaf dimensions and appearance.
