The fruit stalks are upright. The capsule fruit is four-lobed.

The basic chromosome number is x = 7, there is tetraploidy , i.e. 2n = 28.

In Central Europe and on the British Isles on the coasts of the North Sea and the Baltic Sea, it populates open sandy areas in the outer dike area, but also goes into gappy salt marshes.
