Always tricky to tell S. anglicum from S. album when not in full flower. S. album ususally has a large number of flowers in the inflorescence, whereas S. anglicum often has only one per stem. It's a bit difficult to see in this specimen, but I think you're probably right.

Definitely - I mused on this one for a while but went with anglicum due to the more mat-forming habit evident in several specimens there, plus I seem to remember looking at the inflorescence at the time. The 'probably but I can't be sure' tag seemed appropriate!
