Does anyone know what this plant is? It was growing on an piece of waste ground, here in Yorkshire, and was about 25cm high. The flowers are about 2.5-3cm across. Thanks.
-
These are really bad photos, if you need better I'll try again later when the other camera is home!
-
Niger?
-
Jolly close but I googled it to www.aphotoflora.com, and it's not right. Sepals are pointed and narrow on mine, and the leaf bases are clasping.
-
David Fenwick's site!
-
any tighter shots?
-
Here are some more shots.

I do hope that it is not Senecio inaequidens which finally reached the UK and Ireland. This is an Southafrican escaped weed, the seeds were introduced to Germany together with wool.
It is a specialist for very dry conditions and covers the margins of the
' Autobahn ' for endless kilometers here. Unfortunately quite hardy.

Oh, Gerd, you are right! :o

I hope you will not send your American squirrels to the continent in return.

Funnily enough, I have a trap set for one underneath my hazelnut bush just now, so beware!
-
Didn't catch the squirrel >:(
Since you did so well on the composite, how about this crucifer? I've spent ages looking through books and the net. It's about 25cm across, and I think the flowers were yellow. Note the leaves are hairy.
-
If the flowers are white not yellow then it looks like what we call "Flick Weed" (because when mature any touch sends the seeds flicking off for great distances). If so, it's an absolute bane of our existence here, seeding prolifically and becoming an absolute pain in the proverbial.
But, judging by my recent comments on things I'm likely to be wrong, which in this case would be a good thing!! ;D I do know that there are other not-as-invasive species of the plant, including a double flowered form that doesn't set seed and has lovely pink flowers..... but it produces offsets on teh surface of the leaves which concerns me as well. I can't bring myself to even try it given how bad the flick weed is. Hopefully someone else comes up with something better and less seedy for you identification-wise.
-
Sorry, don't know what it is. Does not grow along the Autobahn.
Gerd
-
OK, as far as I can work out our flick weed here looks just like (and I am assuming IS) Cardamine hirsuta......

Also known as Hairy Bittercress apparently.
The leaves on yours look a little different, but close enough and similar enough seedpod etc that I'd have to be putting it very closely into the same family. Does that help you in identification?
-
Thanks Paul, I'm unfortunately well acquainted with Hairy Bittercress - we call it poppers. This plant was altogether bigger.

Anne
is it an Erucastrum gallicum - sometimes called hairy rocket? http://www.colinherb.com/Cruciferae/Erucastrum/Gallicum/Erucastrum_gallicum.htm (http://www.colinherb.com/Cruciferae/Erucastrum/Gallicum/Erucastrum_gallicum.htm)

Hmm, no, the leaves are different.
-
Funny thing,is, the leaves of the mystery crucifer are very like a ragwort of some sort, aren't they?
How clever nature is at confusing us... almost as cunning as those ******taxonomists! ;D
-
Could be Wintercress (Barbarea vulgaris), but then again it has glossy leaves?
-
Perhaps Eastern Rocket (Sisymbrium orientale)?
edit: as a suggestion for the composite ?
-
Anne,
Ah well, I was right..... I got it wrong. Not having a good run for helping at the moment. That's 3 recent strikes, so I'm out!! ;D
-
You are suffering under the disadvantage of being several thousand miles away from the British flora, Paul!
Anthony I think this one is Barbarea verna, maybe?
-
Looks like Wavy Bitter-cress (Cardamine flexuosa)
-
That's 3 recent strikes, so I'm out!!
Okay, the cake's on you, then!
-
I thought you said the flowers were yellow Anne?
-
Well, I think I saw yellow flowers on another plant of it. Google's pics of Cardamine flexuosa don't have the right leaves either :-\
-
Ann I am most likely being a complete IDIOT but it lokks very much like water cress, I have it in my pond and if it gets to thick I throw it on spare ground and it grows just like that.
Derek
-
I see what you mean, Derek, but I think the leaves are too hairy for water cress.
-
I've got to go back next week so I'll bring back a hostage if I can find it again.
-
Anne,
Please look at my posting to Ashley (Townsendia).
