was gilva = yellow. Now sunk in mammosa - but lacks the basal dimples. Saw another, high up, closer to the parking.
The 1st is a bud, the 2nd, an open flower and the 3rd a bud with the stamens protruding through the petals. I noticed quite a few like this on Black hill, and haven't noticed them before.( Not that that is saying anything as I may not have noticed them)
