Found with other ephemerals on Lyth Hill, Shropshire
No interactions present.
One of the key differences between this and S. marina is the colour of the stipules - the small structures found at the base of the leaf stalks. S. rubra has silvery stipules, S. marina brown ones. These look silver to me - so I reckon you're right!

Thanks Chris. That's not a feature I'd heard of before. A useful one with no seeds to hand.
