Can anyone help ID this wild flowering plant please?

Oxfordshire, upper Thames lock landing stage yesterday.

The nearest I can find is Annual Wall Rocket but this is shorter and the flowers don't have 4 conspicuous petals ...

@MereDintOfPandiculation you are good at this stuff 🙏

TIA

Bog yellowcress?

It looks a bit like a somewhat stunted oil seed rape plant to me!

Have no clue, but there's great place for tis.

It does!

Yes, I’d also say stunted oil seed rape too

is it field mustard?

Thanks for all the replies, if it's oilseed rape that would explain why my wild flower book doesn't list it ....

It might be common wintercress, barbarea vugaris - that's the closest I can get, but I can't help wondering whether it's a hybrid. There are so many in that family, it's hard to tell. It looks a bit like yellow rocket as well.

I've uploaded a screenshot to Plantnet which says 83% chance it's bog yellowcress as ohsheglows mentioned.

You do see oilseed rape dotted about in odd places though.

@ohsheglows , @Weeditandreap

Yes. It's Bog Yellowcress, rorippa palustris

Thank you
