Description
The plants are up to 10 cm high and green. The axis is less than 0.5 mm in diameter. The branchlets are divided two or three times, the secondary rays are much shorter than other rays, and this give the whorls a characteristic, condensed appearance, like heads. The dactyls are 2 or 3 –celled and the end-cells are usually mucronate. The species is monoecious. The gametangia are commonly numerous and most often they are at the second furcation of the branchlets. The oospore is black and has prominent ridges and a granulate membrane.
Habitat
Nitella wahlbergiana is mainly found in fresh water, often in Lobelia-lakes but also in mesotrophic lakes and rivers. A few records are from brackish water, especially near river-outlets, as with the Norwegian locality. The species is found down to 2 m depth.
The species is annual, and is normally found from July to October, both in Sweden and Finland.
