I know what you are thinking: What is this? First a dandelion then a bloody buttercup! Oh right it isn't is it, it's Greater Buggerwort or something, yeah? No, its a Meadow Buttercup (Ranunculus acris) and I can't really do it justice but what you should do is go to Hatfield Forest near Stansted Airport in May or June and walk around the meadows there until your feet are bright yellow. And then think about signing the petition against further expansion of the airport
