Tricky Milkwort

Observation - Tricky Milkwort. Description: My first idea was that this would be Heath milkwort (Polygala serpyllifolia), but on closer inspection it lacks opposite leaves, however, neither do the leaves reflect P. vulgaris. I am actually wondering if this might be Polygala calcarea - Chalk Milk

My first idea was that this would be Heath milkwort (Polygala serpyllifolia), but on closer inspection it lacks opposite leaves, however, neither do the leaves reflect P. vulgaris.

I am actually wondering if this might be Polygala calcarea - Chalk Milkwort... but can't be sure.
