Alpine flower identification — Italy/France
This is not Jasione montana, but Phyteuma orbiculare, another member of the family Campanulaceae. Except for the different flowers,
Jasione has no leaves on the upper part of the stem. This plant has. And these leaves are toothed and have a heart-shaped base, unlike Jasione.
And finally: Phyteuma is resticted to calcarious soils, whereas Jasione prefers non-calcarious soils.
