Is this a Clematis or?

Looks like a Clematis to me, narrowing it down is more difficult as there are quite a few with white four petaled flowers with 'fluffy' centres (technical term  )
Is it scented, and is it flowering now? More info might narrow the list down 

The photos were taken today, no smell though.

I think it is Old man's beard aka (Clematis vitalba) a 'wild growing type that has hundreds of small star shaped blooms from July to September, seen generally in hedgerows and trees along the roadside.' https://www.taylorsclematis.co.uk/clematis-vitalba-oldmans-beard.html

Isn't it the same as the 'photos I posted ?   and the answer was Myrtle.    Mrs Bouquet

Myrtle has 5 petals, cressrt's plant has only 4 

Slap wrists Mrs B.    Look carefully in future.        Whatever it is, it's very pretty.      Mrs Bouquet
