6c Chara hispida var. major (Hartm.) R.D.Wood
This, the largest of the C. hispida aggregate and the largest European species of
Chara, is apparently rare in the Essex, and is only known to have persisted in the
lake at Hatfield Forest, where it has been noted at intervals since c.1820. It re-
appeared in 1985 growing amongst considerable quantities of discarded, green nylon
fishing line, that had accummulated in the decoy cut-off since it was enlarged, and
since a pristine Chalky Boulder Clay bottom was exposed for it to colonise. As this
robust species often occurs in large bodies of water elsewhere, we may be overlooking
it in some of our larger fishing lakes and reservoirs on the Chalky Boulder Clay.
