Yellow-juiced poppy

Up early, and off to work. Seven hours was spent surveying arable ditches, covering just over 8km in total, much of it on rough, ankle-turning ground. The ditch sides were steep and slippery, making sampling treacherous and most of the time we were surrounded by monotonous fields of maize. I found a few rather local arable weeds including this yellow-juiced poppy, which looks very like the rather more common long-headed poppy, but when you break the stem it exudes chrome-yellow juice. 

A delicious meal of pot-roast venison followed by blackcurrant and apple cobbler was very welcome, although it's production was a bit haphazard as I was trying to identify specimens!
