Are the flowers daisy-like? I can't tell from the photo. If it is daisy-like, in clusters/panicles, could it be Smooth Hawksbeard (Crepis capillaris)? The leaves are lanceolate with clasping bases. Also there would be many 'petals'. Does this sound likely? Dandelion types are v. difficult!

No the flower isn't daisy like. On the one small one I picked (which withered extremely quickly) it looks like there are four petals with an undulating edge although that could actually be more petals. I've been on loads of websites and am really stumped.

Does the above suggested Nipplewort sound right? Nipplewort would have narrow upper leaves(as you described)and broader basal leaves. It definately sounds possible!

It probably is nipplewort. The picture in my flower book doesn't look as delicate as the one I saw but other images on the web are definitely similar. Thanks everyone.
