Glandular

Sorry for the naive question cicuta58, but what is it that you mean by "glandular" in this case?

Petals

And another question please to cicuta58, sorry to be a pain. This has 4 notched petals I thought Common Mouse Ear had 5 but I might be under a misapprehension. Regards Chris.

Answers, I hope.

Glands are sticky blobs which should be on short stalks on the sepals in Sea Mouse-ear. They can unstalked in other species and not necessarily sticky. Common Mouse-ear isn't restricted to 5 petals nor Sea to 4 (plants often don't read the books!). However, on enlarging photo 1, there are clearly only 4 styles and probably glands on the bud behind, which fits C. diffusum. I am wondering if photo 3 was a different plant and both species are represented? Common would be perennial and Sea annual, but that is hard to tell. Photo 3 looks darker green. I will signal agreement with Sea Mouse-ear! Very interesting!

Additional info

Many thanks cicuta58. I have now uploaded the other 2 photos that were taken of the plant in the hope that these might help. All were taken with the same camera. The plant was growing on one of the stones in the castle ruins, separated from any other plants, which might indicate that it is only one species (unless there is some coincidence at play or the 2 species like growing together at the same spot).
