E. farctus subsp. farctus x E. pycnanthus and x E. repens are widespread in the Mediterranean region; subsp. boreali-atlanticus * E. pycnanthus (2/2 = 35) and subsp. boreali-atlanticus x E. repens (2/2 = 35, 49) occur commonly on the west coast of Europe.

E. farctus subsp. boreali-atlanticus x Leymus arenarius occurs occasionally on maritime sands in the Baltic region. It is morphologically intermediate between the parents and is sterile. E. repens x Leymus arenarius has also been recorded from maritime sands in arctic Russia.
