Autumnal starwort
Callitriche hermaphroditica (syn.C. autumnalis)
This submerged perennial has thin branching stems which can grow up to 50cm (20") long. The leaves are small, narrow and light green in colour, 3cm long and 1mm wide.
It is an excellent oxygenator and therefore makes a good hiding place for freshwater fleas, shrimps and newborn fish fry all of which need good supplies of oxygen.
It does not develop surface rosettes, unlike most starworts and grows mainly near the bottom of the pond.
