ID : Goosefoot or Dock Species.

Graham,

Black Mustard Brassica nigra did cross my mind but the fruit capsules don't fit. Black Mustard has smaller capsules which are tight to the axis and with shorter beaks.

I'm still sticking to Charlock.

Hello,

I must have missed you Phil. I was back there today with a friend this morning and had another look with the books to hand. There were both Charlock and Black Mustard present. Panic over. I have some images that I will try to post later if I get a chance.

It was good to return though as I saw the Annual Mercury this time.

Regards,
Andrew.

It is Charlock - Sinapis arvensis. And as aeshna5 has pointed out, I don't think it would have been possible to arrive at an ID from the original two leaves and a flower-bud.

I think the 'leaf' that Andrew first picked was a terminal leaflet giving no indication of leaves being pinnate.
So yes problem solved and many thanks to Phil for the extra material.
I think it is a lesson to us all: as much detail as possible can make all the difference.

I now have to embarrass my friend with the news!

Hello,

I have uploaded the images and I still think there are two plants involved here. Black Mustard yet to flower and Charlock in flower. The first three images show what I believe is the Black Mustard and the last two show the Charlock which had no basal leaves.

Regards,
Andrew.

Andrew,

You are probably right when you say Brassica nigra is present as well. Just the right habitat and I certainly couldn't tell Charlock and Black Mustard apart when the plants are young.

Regards,
Phil
