        Flats, 26 October 2004 | More | |||||
| This was present in the newly-renovated Jubilee Pond in 2004, probably accidentally introduced together with other water-plants brought from further north in Epping Forest. After the pond was re-lined following leakage, much of the vegetation and plant-species that had been establishing were lost, and this species was not noted during 2016. | |||||
