Mesterházy Attila, Csiky János, Pál Róbert, Tari László & Pinke Gyula
Najas gracillima, an introduced species to Europe, naturally occurs in East-Asia and North-America. It was firstly discovered in Hungary in 2012 during our weed survey of rice fields in the vicinity of Szarvas, Gyomaendrőd and Mezőtúr. Although, it occurred in relatively high abundances in the rice fields along the Körös river its invasion is not expected into new habitats in the near future due to its special habitat preference and gregariousness.
