Sun Spurge...

.. Euphorbia helioscopa, has umbels that are usually 5-fayed, with a clearly visible rosette of umbel bracts which are obovate - egg-shaped.

Petty Spurge, E. peplus, is usually only 3-rayed (ie three stems above the rosette of bracts) and those bracts are more triangular than oval.

I can't tell from your photos which this is likely to be, but I hope that the ID pointer above is of use, next time!

Oh, and of course petty spurge is "a smaller version" of sun spurge, but don't you find that descriptions like that are useless unless you have two healthy, typical specimens, one of each, side by side? *laughs*

That's really helpful,

That's really helpful, thanks, Rachy - I've learned something there and I'll have a good look next time I'm at the churchyard.

"5-fayed"?

Glad that you are more intelligent that my fingers are, Steve, you realised that I meant 5-rayed there.....

You're welcome, anyway.
