I'm not sure about this umbellifer. A striking-looking plant though. Growing at the back of the beach. Edit - Wild Carrot - thank you Dave!
I think I've finally found some Bithynian Vetch - none whatsoever in flower yet though.
Absolutely masses of Small-flowered Buttercups are growing around the caravans at Sandy Bay.
I misidentified Slender Trefoil at the weekend. Could this be it?
