(Map updated: March 2008)
 

Water milfoils are submerged aquatic species with feathery leaves, although the flower spikes are held above the water. The flowers are small and unremarkable.

All occur in still or slow-moving water (lakes, ponds, flooded quarries, drainage ditches, slow streams etc). Myriophyllum verticillatum is very rare except around Lough Erne in Co Fermanagh.

All names: Myriophyllum verticillatum L.; Myriophyllum pectinatum DC.
