[rambo3]

they are bushes abt 2-3 metres high with thorns abt 2-3 centimetres long.they cover all hills of cumbria and lake district in northern england at this time of year spring.they are definitely not dandelions.my wife who is a botany and plant expert is mystified what they are as we are presently travelling in this part of the world.

Here is a link that might help. It doesn't sound like a helliobore but it might be. When I travel and see unusual plants I often press a sample to check on later, or ask locals what it is. Even if they only provide a regional common name it helps when I research it. I am fascinated by the unusual species I find when traveling, with hundreds of thousands of plants in the world there is no shortage of interesting ones. http://www.cumbria-wildlife.org.uk/helleborines.html
