At Filsham today I stumbled across a pond with a nice muddy margin. I almost immediately groaned as I saw it was covered in (what i thought was) New Zealand Pygmyweed. A closer inspection showed it to be a water starwort and upon looking more closely at it, I realised it was Intermediate Water-starwort. This species looks to be the second commonest water-starwort after common, still it's a new one for me. The pond was also full of Fine-leaved Water-dropwort. I end the day on 3692 species.
