Sorry if I'm reinventing the wheel but a person posted this on another site
and I can't see that they've had an answer. Any idea what this is? There
are close-ups available, it looks like a mallow of some sort.

Probably Malva moschata alba (white musk mallow) - there's a white form
of Malva alcea, but that's so rare I've never seen it. (The easiest
distinguishing characters for Malva alcea and Malva moschata are not
shown in the photographs.)

The overall look is exactly right for moschata - I have a lot of it
growing in my garden.
