Callitriche brutia - Pedunculate Water-starwort
Pedunculate Water-starwort is found in shallow, muddy pools, on poached ground and in trackways subject to winter flooding. When growing in water the long-stalked fruits are clear, but short-stalked forms occur at the edges of pools where drying out has taken place. The first Cornish records were for moors, both on Land's End and Bodmin Moor, but recent work has shown the species to be more widespread, occurring on the Lizard as well as in several sites on Bodmin Moor. It has also been found in a pond near Pennatillie (SW96D) and in disused china clay pits, as at Hawk's Tor (SX17M), and is recorded on the Isles of Scilly.
