Resum

In this new note, the series started previously (MOLINA ABRIL, 1992a) based on the studies of the helophytic flora and vegetation in the Central System (MOLINA ABRIL, 1992b) is continued. Chorological and phytosociological comments are provided for nineteen taxa collected in the central Iberian Peninsula. Likewise, the following distribution maps are aported: Apium repens and Catabrosa aquática in the Iberian Peninsula, Littorella uniflora in Spain, and Alisma plantago-aquatica and Alisma lanceolatum in the Spanish Central System; their patterns of distribution are commented and related with autoecological and synecological aspects. Taxonomic differential characters between Alisma plantago-aquatica /Alisma lanceolatum and Apium repens /A. nodiflorum are discussed.
