upright hedge parsley,cow parsley,hemlock ?
No interactions present.
It is useful to be able to see them all together, but not possible to use the ispot system to name them effectively like this!
I think the left hand one is cow parsley, Anthriscus sylvestris, the centre one is Rough Chervil and the one on the right might well be hemlock, though I'm less confident with that one (though usually have no trouble identifying it in the wild - just looks a bit odd to me).
Rough chervil (Chaerophyllum temulum) is hairier than Cow parsley, and the secondary pinnae are flatter and have stalks (cow parsley secondary pinnae don't have stalks as far as I've noticed - but there may be exceptions).
Upright hedge parsley isn't as far on as the others round here yet.
Hope that helps a bit.
the right one had red streaked (hemlock like)stems.
I shall have to look at hemlock more carefully next time I see it. It's usually a gut feel - that's hemlock, without really knowing why, other than it's more finely divided. Still looks a bit odd, but the spots fit. Maybe someone else will be surer.

That one looks right. Perhaps the leaves just haven't opened out fully yet?
