I spotted this bindweed with lobed flowers.
I don't remember seeing one like this before but the last image is of a separate plant I saw 30 mins later.
No interactions present.
Thanks for the revised ID.
I can't find much info about this on line and I'm surprised to see no other examples here.
The BSBI has only 11 records in total; 2 in County Cork, 1 in County Waterford, 1 in Surrey, 1 in Outer London, 1 in Birmingham, 1 in the Black Country and 1 south of Manchester, and 3 in Teeside not resolved to tetrad.
Google images finds another one (but rather less lobed) from Leicestershire, and an Irish specimens which is very deeply lobed.
I expect that it is underrecorded to some degree. Stace says "deeply 5-lobed", so the Leicestershire specimen doesn't qualify; yours depends on where the line is drawn. You'll have to see what the county recorder thinks.
