General Environment
This is a freshwater species.

Description
Nitella flexilis differ from Nitella opaca by being monoecious. It is not possible to separate the two species in sterile condition.

Habitat
Nitella flexilis is found in many types of habitats; Lobelia lakes, Potamogeton-lakes, high mountain lakes, small ponds, ditches, rivers and also slightly brackish water, but it seems to prefer soft oligotrophic waters. N. flexilis is also found in cold areas. Kashimura (1969) found that the species developed best at low temperatures, with the best growth of the gametangia at 5-10oC. The species has fertile plants from May to September and ripe, black oospores from July onwards. N. flexilis var. fryeri is markedly protandrous. It has been found in Norway. In some lakes, probably with unfavourable conditions (temperature) one can find only sterile specimens which must be named Nitella opaca vel flexilis.
