Flower I.D.s please

[Fieldfare95]

Hi, today I have been helping my granddad on his allotment. On the site a big(unused) plot was turned into a nature reserve and today I have found some plants that I can't id. I took some(rubbish) pictures on my phone:

The flowers on this plant are yellow and the stem and leaves were very thin(not the ones you can see):


Not sure what this is:


Some sort of spurge?:


And I think this is a fringed water lily:

You're right about Fringed Water-lily.

Pink flower is Hairy/Great Willowherb

Spurge is Petty Spurge.

Not sure about 1 but probably a Brassica sp.

Thanks very much
As for number 1, I now think it is hedge mustard.

I agree that it isn't Hedge Mustard - but it's not Black Mustard either - the fruits are wrong.

No, both Black Mustard and Hirschfeldia have the fruits held close to the stem, in Fieldfare's pic they stick out from the stem.

Thanks for all the replies
As for the mustard, I'm really not sure. But I really need to get a better field guide-the one I've got doesn't include all the species.

Got it The mustard is Treacle Mustard - Erysimum cheiranthoides

The flowers are the right colour and the lanceolate leaves correspond with this species

As you found the plant on an allotment, and going by the shape of the fruits, my best guess is that your plant is Charlock, Sinapis arvensis, also known as (so my book says) Kilk, Wild Mustard, and Brassocks. But I have never heard it called anything other than Charlock.
