The separate position of Helosciadium is supported also by morphological characters and fruit anatomy (Ronse et al. 2010). Five taxonomic units of the genus Helosciadium are reported until now for the Euro-Mediterranean area (Hand 2011): H. bermejoi (Llorens 1982: 28) Popper & M.F.Watson in Ronse et al. (2010: 12), H. crassipes Koch (1824: 126), H. inundatum (Linnaeus 1753: 253) Koch (1824: 126), H. nodiflorum (Linnaeus 1753: 251) Koch (1824: 126), and H. repens (Jacquin 1775: 34) Koch (1824: 126). However, Apium nodiflorum (L.) Lagasca y Segura (1821: 101) subsp. mairei Molina Abril & Sardinero (1996: 278) was described as a subspecies endemic to Morocco and Algeria. For this unit, we propose here a new combination under Helosciadium.Helosciadium nodiflorum (L.) W.D.J.Koch subsp. mairei (Molina Abril & Sard.Rosc.)
