1. I took this yesterday at Wilstone Reservoir near Tring. I think it is a better example of the Goldilocks Buttercup that people kindly identified for me the other day.
The remaining photos were taken from my stumblings along the Bucks/Herts border in the Chiltern Hills today:-
2. I think this one is Wood Speedwell.
3. This is obviously a Violet, but which one please?
4. I think this is another example of Wavy Bittercress (which Tiggrx and Bub-les ID'd for me yesterday) - a close-up of one of the photos shows that it has the correct number of stamens (6):
5. A buttercup (obviously!) but which one please?
6. Sorry, I haven't been able to work this last one out at all. If it's any help it was beside a woodland path (next to what I think is the Wood Speedwell), on presumably rather chalky soil as I was in the Chiltern Hills.
