Confirmed by Peter as [common water-starwort] 2nd July Callitriche stagnalis
Looks a lot like Duck Weed but the leaves are a bit more oblong and have clear veins ??
UPDATE July 3rd
Peter Nicholson has suggested it may be a 'starwort' here is an image of the [common water starwort] that is similar to the above. https://www.naturescape.co.uk/product/common-water-starwort/ Common water-starwort Callitriche stagnalis

A new discovery. Whilst showing Pete Nicholson around as he was looking for site to establish Triangular club rush he pointed out a mass of 'Newzealnd Pygmyweed'' by the damaged drain in the gully going north.

Just to confirm that the mass of green mat plants growing in the tidal ditch that we crossed via the log ditch were in fact common water-starwort, Callitriche stagnalis.
