Apium inundatum x nodiflorum (A. x moorei)
(Map updated: March 2008)
 

This is thought to be the hybrid between Apium inundatum and Apium nodiflorum. It is a rare plant, much less common than its supposed parents. Most records are from Lough Neagh and Lough Erne. It resembles Apium inundatum in size but the submerged leaves are not finely divided.

All names: Apium inundatum x nodiflorum (A. x moorei) (Syme) Druce; Apium x moorei (Syme) Druce; Apium inundatum x nodiflorum
