Colour

I would expect the flower to be all one colour for subsp. nigra, whereas subsp. segetalis is two-toned as here.

Leaves

But the leaves are different and much thinner in ssp nigra as seen here.

Leaves

I find the leaves of segetalis vary quite a lot. Other characters are more useful.

Vetch

Go back when seed pods ripe - their differences should decide the issue.

Leaves

I agree with Cicuta on this one - the leaves in sat seg can be narrow, particularly on the upper parts of the plant. When you see a true sat nigra it has a much smaller, darker flower which is concolorous. I will put this down as sativa segetum as far as the atlas records are concerned.
